7202 ACCBM Bearing Structural Features & Performance Benefits
Precision Engineering: Manufactured to P6 tolerance class (equivalent to ABEC-3), this bearing ensures minimal runout and vibration for smooth operation in precision machinery.
High-Speed Performance: The machined brass cage (CC designation) provides excellent dimensional stability and strength at high rotational speeds, contributing to the bearing's 40,000 rpm limiting speed.
Load Capacity: With a 25° contact angle and optimized raceway geometry, the bearing delivers superior performance under combined radial and axial loads, featuring a dynamic load rating of 2,295 lbf and static load rating of 1,170 lbf.
Material Quality: Constructed from chrome steel for both rings and balls, ensuring high hardness, wear resistance, and long service life in demanding applications.
7202 ACCBM Bearing Typical Application Areas
- Machine tool spindles requiring high precision and rotational accuracy
- High-speed motors and generators where reliable performance at elevated speeds is critical
- Precision gearboxes and transmission systems needing stable axial positioning
- Industrial pumps and compressors operating under combined loading conditions
