KG090AR0 Bearing Structural Features & Performance Benefits
Optimized Thin Section Design: The KG090AR0 features a 1" width with large bore diameter (9") and outside diameter (11"), providing maximum space utilization while maintaining structural integrity. The single-row construction with 30° contact angle ensures efficient handling of combined loads.
High Load Capacity: With a radial dynamic load rating of 9,073 lbf and axial static load rating of 21,640 lbf, this bearing delivers exceptional performance under demanding operating conditions. The static load moment rating of 54,720 lbf ensures stability in moment-loaded applications.
Precision Engineering: Manufactured to ABEC-1 tolerance class with tight dimensional control (bore tolerance: -0.0012" to 0", OD tolerance: -0.0012" to 0"). The brass cage provides superior guidance and durability, while the radial internal clearance of 0.0000-0.0005" ensures optimal running performance.
Material Excellence: Constructed from chrome steel rings and balls for superior hardness and wear resistance, ensuring long service life in precision applications.
