KF040XP0M Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry enables the bearing to support substantial combined radial and axial loads from any direction, making it ideal for applications with complex loading conditions.
Thin Section Construction: With a compact cross-section (0.75" width) relative to its bore diameter (4"), this bearing provides significant space and weight savings while maintaining high rigidity and structural integrity.
Premium Material Composition: Constructed from chrome steel rings and balls with a brass cage, the bearing offers excellent durability, corrosion resistance, and stable performance across the operating temperature range of -30°C to 110°C.
High Load Capacity: The bearing delivers exceptional load ratings with radial dynamic load capacity of 4665 lbf and axial dynamic load capacity of 6830 lbf, ensuring reliable performance under demanding conditions.
KF040XP0M Bearing Typical Application Areas
The KF040XP0M thin section bearing is ideally suited for:
- Robotics and automation systems requiring compact, high-precision components
- Aerospace and defense equipment where weight reduction is critical
- Medical imaging devices and precision instrumentation
