7338 BCBM Bearing Structural Features & Performance Benefits
Optimized Internal Geometry: The 40° contact angle provides excellent axial load carrying capacity while maintaining effective radial load performance. The calculated distance from side face to load point (164mm) ensures optimal moment load distribution.
Premium Material Construction: Manufactured from chrome steel for rings and balls with a brass cage, delivering superior strength, wear resistance, and dimensional stability under varying operating conditions.
High-Speed Capability: With a limiting speed of 2,200 rpm, this bearing is engineered for efficient high-speed operation, supported by the brass cage's excellent mechanical properties.
Exceptional Load Capacity: Rated for dynamic load capacity of 99,450 lbf and static load capacity of 135,000 lbf, making it suitable for heavy-duty applications requiring reliable performance under significant loads.
Precision Engineering: Manufactured to P6 tolerance class (equivalent to ABEC-3) with tight dimensional controls on bore, outside diameter, and width for consistent, high-precision performance.
