Angular Contact Ball Bearings are designed to accommodate combined radial and axial loads while maintaining accurate and stable rotation. Their raceways are positioned at an angle to the bearing axis, creating a contact angle that determines how the bearing responds to axial loading, rotational speed and operating conditions.
BMT supplies Angular Contact Ball Bearings for OEM equipment manufacturers, bearing distributors, maintenance suppliers and industrial machinery companies. Our range covers compact miniature sizes, standard metric series, double-row configurations and matched bearing arrangements for applications requiring controlled axial positioning and reliable radial support.
Different contact angles, seal configurations and bearing arrangements allow buyers to select a suitable solution according to load direction, speed, available installation space and equipment design.
BMT's Bearings range includes several commonly used bearing series, covering different dimensions and application requirements.
| Bearing Series | Main Characteristics | Typical Selection |
|---|---|---|
| 30/5–30/8 | Compact miniature angular contact bearings | Small mechanisms, precision assemblies and compact equipment |
| 3000 Series | Standard angular contact bearing dimensions | General industrial equipment and rotating assemblies |
| 3200 Series | Double-row angular contact configuration | Combined radial and axial loads where a compact arrangement is required |
| 3300 Series | Wider double-row configuration with higher load capacity | Machinery and equipment requiring greater load support |
| 3800 Series | Compact section angular contact bearings | Space-limited mechanisms and industrial assemblies |
| 7200B Series | Single-row configuration with defined contact angles | Motors, pumps, machine tools and precision rotating equipment |
| 7300B Series | Larger single-row angular contact bearings | Higher-load machinery and industrial transmission systems |
| 7400 ACM / BM | Different contact-angle options | Applications requiring different axial-load and speed characteristics |
| QJ Series | Four-point contact configuration | Bidirectional axial load applications and compact bearing arrangements |
| VLU / VSU Series | Large-size bearing configurations | Heavy industrial equipment and large rotating structures |
The contact angle is one of the important factors when selecting an Angular Contact Ball Bearing. A smaller angle generally favors higher-speed operation, while a larger angle provides greater capacity for axial loading.
BMT offers configurations with different contact-angle specifications, including 25°, 40° and other application-specific designs in the available series.
For OEM applications, bearing selection should consider the actual combination of radial load, axial load, rotational speed, preload, lubrication, operating temperature and mounting arrangement rather than contact angle alone.

For standard purchasing, buyers can specify the bearing model and required quantity. For OEM projects, BMT can evaluate requirements based on a drawing, existing bearing number or equipment specifications.
Depending on the series, available options may include:
This makes the range suitable for both regular bearing procurement and application-specific OEM projects.

BMT's product range is suited to buyers who need more than a single standard bearing size. The combination of standard bearing series, multiple configurations and OEM support allows distributors and equipment manufacturers to consolidate different bearing requirements with one supplier.
For recurring orders, BMT can work with approved specifications and production requirements. For new equipment projects, the buyer can provide drawings or operating conditions so that the bearing configuration can be evaluated before quotation.

They are commonly used where radial and axial loads occur together, including machine tools, motors, pumps, automotive systems, agricultural machinery and industrial transmission equipment.
Single-row bearings are commonly selected for applications where controlled axial loading and high-speed rotation are important. Double-row configurations can provide support for combined loads within a compact bearing arrangement.
Yes. Depending on the model, BMT offers open, 2RS rubber-sealed and 2Z metal-shielded configurations.
Yes. OEM projects can be evaluated according to bearing drawings, dimensions, equipment requirements, internal clearance, cage configuration and lubrication requirements.
Start with the shaft diameter, housing dimensions, radial and axial loads, operating speed, temperature, lubrication and mounting arrangement. For OEM projects, providing the equipment operating conditions allows a more accurate selection.
