7088 BM Bearing Product Overview & Core Advantages
The 7088 BM is a single row angular contact ball bearing engineered for applications demanding high precision and robust performance under significant combined loads. Its 40° contact angle is optimized to efficiently handle substantial axial loads in one direction alongside radial loads, making it a high-rigidity solution for critical machinery. Manufactured to a P6 (ABEC-3) tolerance class, this bearing offers exceptional running accuracy and reliability. The open design, combined with a brass cage, facilitates high-speed operation and is supplied pre-lubricated for immediate installation and long-term performance.

7088 BM Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle and precisely calculated raceway geometry are fundamental to its high axial load rating and high rigidity, ensuring minimal deflection under load.
Superior Load Capacity: With a dynamic load rating of 128,700 lbf and a static load rating of 265,500 lbf, this bearing is built to withstand demanding combined loads in challenging industrial environments.
High-Speed Capability: The use of a brass cage (M) ensures dimensional stability and low friction at high rotational speeds, contributing to a reliable limiting speed of 950 rpm.
Precision Engineering: Conforming to the P6 tolerance class, this bearing guarantees precise shaft running and reduced vibration, which is critical for the accuracy of the overall system.
7088 BM Bearing Typical Application Areas
The 7088 BM is ideally suited for heavy-duty machinery and precision equipment where high axial and radial loads are present. Key industries and applications include:
- Heavy-Duty Pumps and Compressors
- Large Industrial Gearboxes
- Machine Tool Spindles
- Mining and Construction Equipment
