Spherical Roller Bearings are roller bearing products provided by BMT Bearings for heavy-duty industrial equipment. They feature a double-row spherical roller structure, which can withstand high radial loads and accommodate shaft deflection and a certain degree of mounting misalignment. As a professional manufacturer in China, BMT Bearings has established a production system covering material inspection, machining, assembly, and performance testing. The product range includes series 213, 222, 223, 230, 231, 232, 239, 240, and others, serving industrial applications such as mining equipment, construction machinery, metallurgical systems, and paper-making machinery.
Spherical Roller Bearings are rolling bearings equipped with two rows of spherical rollers. Since the outer raceway has a spherical shape, the bearings provide self-aligning capability and can automatically compensate for angular errors caused by shaft or housing misalignment. These bearings are suitable for industrial equipment subject to heavy loads, shock loads, and possible shaft deflection or misalignment. The double-row spherical roller structure provides a stable load transmission path inside the bearing while accommodating shaft deflection and mounting errors that may occur during operation.
The double-row spherical rollers share the operating load, making the bearings suitable for high radial loads. This structure is designed for heavy-duty equipment such as mining machinery, metallurgical equipment, and construction machinery.
The spherical outer raceway design provides good self-aligning capability and can effectively compensate for angular misalignment caused by shaft bending or mounting errors, helping maintain a more even load distribution.
The products can accommodate a certain degree of shaft misalignment and deflection. When equipment is subject to shaft bending, mounting errors, or load variations, the bearing's self-aligning capability should be carefully evaluated.
They are suitable for industrial applications such as mining equipment, construction machinery, metallurgical systems, and paper-making machinery.
BMT spherical roller bearings are suitable for industrial fields such as mining equipment, construction machinery, metallurgical systems, and paper-making machinery. During actual bearing selection, equipment load, shaft conditions, and mounting requirements should be considered together.
Mining machinery typically operates under heavy mechanical loads and may also be affected by shock loads and shaft misalignment during operation. Spherical Roller Bearings are suitable for heavy radial load conditions and can be used for rotating support and bearing applications in related mining equipment.
Construction machinery frequently experiences load variations and changes in the forces acting on mechanical components during operation. BMT spherical roller bearings can accommodate shaft deflection and a certain degree of misalignment, making them suitable for heavy-duty rotating components in construction machinery.
Transmission and rotating components in metallurgical equipment typically need to withstand high working loads. BMT provides products in multiple sizes and load ratings, allowing procurement personnel to confirm the appropriate model based on shaft diameter, mounting dimensions, and actual operating loads.
Paper-making equipment usually contains rotating components that need to operate continuously. These bearings can be used for bearing replacement and OEM applications in paper-making machinery. The specific model should be confirmed according to the original bearing number, mounting dimensions, and operating load.
We have established a clear four-step quality inspection process to ensure that products are inspected throughout every stage, from raw materials to finished bearings:
Incoming materials are inspected to verify that they meet production requirements before entering the machining process.
Bearing rings, rollers, and other components are inspected for dimensional accuracy and machining quality to ensure that critical parts meet drawing specifications.
The assembled bearings are inspected to verify component fit, assembly condition, and overall assembly quality.
Finished bearings undergo dimensional measurement, vibration testing, noise testing, and performance testing to confirm that they meet the required specifications for shipment.
Designed for the high radial loads and continuous shock loads encountered in equipment such as mining crushers, vibrating screens, and heavy-duty gear reducers, the products use high-purity bearing steel and optimized raceway geometry. The double-row rollers provide excellent load distribution capability and help reduce stress concentration.
With 100 sets of automated grinding and assembly production lines, BMT strictly controls the shape tolerance and surface roughness of the spherical outer raceway. The bearings maintain smooth operation when subjected to mounting angle deviations or shaft bending, helping prevent premature spalling.
To meet the operating stability requirements of heavy-duty conveying and transmission equipment, every bearing undergoes 100% noise (dBA) and vibration (V1~V3) level inspection before shipment, ensuring that the matching between rollers and raceways meets high-precision mechanical standards.
With a modern industrial park covering 30,000 square meters and ISO9001:2000 / IATF 16949:2016 system certifications, BMT can customize clearance, sealing configurations, and lubrication grooves/holes (W33 structure) according to customer requirements.
What equipment are Spherical Roller Bearings suitable for?
