Axial-angular Contact Roller Bearings AXS Series combine axial load support with an angular contact arrangement to accommodate axial and radial forces within the same bearing application. This makes the series suitable for equipment where a conventional radial bearing or axial bearing alone may not provide the required combination of stiffness and load handling.
The AXS range includes multiple sizes and configurations, allowing equipment manufacturers to select a bearing according to shaft diameter, housing dimensions, contact angle, centring tolerance, and basic load ratings. The available models range from AXS0816 and AXS1220 for compact assemblies to AXS160180 and AXS175200 for larger industrial equipment.
For OEM applications, bearing selection depends on more than the outside and inside dimensions. Operating load, mounting tolerance, rotational requirements, space limitations, and the relationship between axial and radial forces all affect the final bearing specification. BMT can work from customer drawings and application requirements when a standard model does not fully match the equipment.

The angular contact arrangement allows the bearing to work under combined loading conditions rather than being limited to a single load direction. This is particularly relevant to mechanisms in which axial force is generated by the working process while radial force comes from shaft rotation, transmission, or other mechanical components. Selecting the appropriate AXS model requires checking the actual load direction and comparing the required capacity with the axial and radial basic load ratings shown in the technical table.
The AXS Series includes models with 45° and 60° contact angles. The contact angle is an important parameter when evaluating how a bearing responds to axial and radial loading. Because the available models are not identical in contact angle, dimensions, and load ratings, equipment designers can use the model data to select a configuration that better fits the mechanical arrangement rather than treating the entire series as one standard specification.
The series provides a broad size range, from the AXS0816 with an 8 mm bore to the AXS175200 with a 175 mm bore. This allows the product family to cover compact precision mechanisms as well as larger industrial assemblies. Shaft diameter, housing size, installation tolerance, and available mounting space should be checked together before selecting the final model.
In machine tools and other precision machinery, bearing selection directly affects shaft support and positioning stability. The AXS Series provides options with defined contact angles, dimensional tolerances, and axial load ratings for equipment where the bearing must accommodate combined forces within a controlled mechanical structure.
Automation equipment, gearboxes, reducers, and high-speed transmission systems can generate changing combinations of axial and radial loads. The AXS range gives equipment manufacturers several dimensional and load-capacity options for integrating the bearing into rotating assemblies where space, shaft size, and load direction must be considered together.
BMT bearing products are used in industrial applications including electric motors and pumps, while the AXS Series is suited to mechanisms that require axial and radial load support. Final selection should be based on the specific shaft, housing, operating load, rotational conditions, and installation requirements of the equipment.
BMT Bearings began bearing manufacturing in 2004 and has developed from its original Yuyao operation into a manufacturer and exporter of ball and roller bearings. In 2005, the company developed non-standard bearings as part of its early product development work. Over the following years, BMT expanded its production and export operations, with annual bearing production reaching more than 20 million pieces in 2007, 30 million in 2008, 50 million in 2012, and 100 million pieces in 2024.
BMT's manufacturing system includes approximately 100 automatic grinding production lines and automatic assembly lines, with annual production capacity of around 100 million sets. Measuring and testing equipment is used to control bearing dimensions and product quality throughout production. For industrial buyers, this production setup provides the manufacturing capacity needed for repeat orders, OEM supply, and ongoing model production.
BMT has been assessed and registered under ISO9001 and IATF 16949:2016 quality management systems. These systems support standardized production and inspection procedures from material storage through machining, assembly, and finished-product inspection. The company also applies EMQ quality standards on selected bearing production lines for applications where running smoothness and noise performance are important.
Not every machine can use an off-the-shelf bearing without modification. Shaft dimensions, housing tolerances, internal arrangement, load direction, or equipment structure may require a non-standard design. BMT's experience in non-standard bearing development allows the engineering team to evaluate customer drawings and application requirements when a catalog model is not sufficient.
For OEM projects, customers can provide bearing drawings, equipment dimensions, working conditions, or required performance parameters for evaluation. BMT can discuss dimensions, material requirements, lubrication, sealing, tolerance, and precision requirements according to the application. This approach is intended to match the bearing specification with the actual machine rather than selecting a model based only on bore and outside diameter.
For industrial equipment manufacturers, consistency between batches is as important as the performance of an individual bearing. BMT uses automated processing, assembly systems, measuring equipment, and inspection procedures to control production quality. Finished bearings are inspected before delivery according to the applicable product requirements.
BMT exports bearing products to international markets and has experience supplying OEM customers and industrial distributors. The company's manufacturing base, quality management systems, and long-term bearing production experience support customers looking for a stable source for recurring bearing requirements.
BMT combines more than 20 years of bearing manufacturing experience with automated grinding and assembly capacity, non-standard bearing development, and established quality management systems. For customers evaluating Axial-angular Contact Roller Bearings AXS Series, the important consideration is not simply the bearing model itself, but whether the model, load rating, contact angle, dimensions, and tolerances match the machine.
BMT can supply the standard AXS models listed above and discuss customized requirements based on customer drawings and operating conditions. For OEMs, distributors, and industrial equipment manufacturers, this provides a practical way to evaluate bearing specifications before moving to production supply.
The AXS Series is designed for applications where the bearing needs to accommodate combined axial and radial loads while maintaining bearing stiffness and rotational accuracy. Typical applications include machine tools, industrial automation equipment, transmission systems, gearboxes, reducers, pumps, electric motors, and other industrial machinery. The correct model should be selected according to shaft size, housing dimensions, load direction, operating conditions, and required accuracy.
The AXS Series includes models with 45° and 60° contact angles. Contact angle affects how the bearing accommodates axial and radial loads, so the appropriate configuration depends on the load relationship and mechanical structure of the equipment. BMT can help customers compare the available models based on actual application requirements rather than selecting a bearing only by its dimensions.
Start with the shaft diameter and available housing space, then check the bearing height, contact angle, shaft and housing tolerances, and basic axial and radial load ratings. Operating speed, load direction, installation conditions, lubrication, and required precision should also be considered. BMT can review customer drawings or application data to help identify a suitable model from the AXS Series.
Yes. BMT has experience in non-standard bearing development dating back to 2005. For applications where standard dimensions or configurations do not meet equipment requirements, customers can provide drawings, dimensions, operating conditions, or other technical requirements for evaluation. BMT can then discuss the required bearing structure and manufacturing specifications for the project.
The current AXS Series specification covers models from AXS0816 through AXS175200. Bore diameters range from 8 mm to 175 mm, allowing the series to cover both compact mechanisms and larger industrial assemblies. Each model has its own dimensions, contact angle, centring tolerance, and axial and radial basic load ratings, which should be checked in the technical table before ordering.
Yes. BMT supplies bearings for OEM applications and supports customers with product requirements based on equipment drawings and operating conditions. OEM projects can involve standard models or customized bearing specifications depending on shaft dimensions, housing tolerances, load requirements, lubrication, sealing, and precision requirements.
BMT uses automated grinding and assembly processes together with dimensional measurement and product testing procedures. The company operates approximately 100 automatic grinding production lines and automatic assembly lines, with annual bearing production capacity of around 100 million sets. BMT has ISO9001 and IATF 16949:2016 quality management systems for standardized production and inspection.
The AXS Series includes models intended for applications where rotational accuracy and bearing stiffness are important. Actual suitability depends on the selected model, load, speed, installation accuracy, lubrication, and operating environment. For precision equipment, BMT recommends confirming the complete bearing specification with the machine requirements before production.
BMT applies EMQ quality standards on selected production lines. EMQ-level manufacturing is particularly relevant to applications where smooth running characteristics and controlled noise performance are important. The applicable quality level should be confirmed according to the specific bearing model and customer requirements.
For an accurate quotation and model evaluation, customers should provide the required bearing model when known, or provide shaft diameter, housing dimensions, axial and radial loads, operating speed, working temperature, lubrication conditions, installation requirements, and expected application. A drawing or existing bearing reference can also help BMT evaluate the requirement more efficiently.
Yes. BMT has an established bearing manufacturing and export operation, with annual bearing production reaching approximately 100 million pieces in 2024.
