KG250AR0 Bearing Product Overview & Core Advantages
The KG250AR0 is a thin-section angular contact ball bearing designed for applications requiring high precision and space optimization. Featuring a single-row construction with a 30° contact angle, this bearing excels at handling combined loads—simultaneously supporting substantial radial forces and unidirectional axial thrust. Its Reali-Slim Open design provides maximum load capacity within minimal cross-sections, making it ideal for compact, weight-sensitive assemblies. Manufactured to ABEC-1 precision tolerances with premium chrome steel components, it delivers reliable performance in demanding operational environments.

KG250AR0 Bearing Structural Features & Performance Benefits
Optimized Thin-Section Design: The bearing's minimal cross-section (1" width) with large bore diameter (25") provides exceptional space efficiency while maintaining structural integrity.
High Load Capacity: Engineered with a 30° contact angle and premium chrome steel construction, it delivers outstanding radial dynamic load rating of 15,239 lbf and axial static load capacity of 40,920 lbf.
Precision Performance: Manufactured to ABEC-1 tolerance class with tight dimensional controls (bore/OD tolerance: -0.0018" to 0") ensures consistent operation in precision applications.
Enhanced Stability: The brass cage provides superior guidance and stability at moderate speeds, while the optimized shoulder diameters ensure proper seating and alignment.
Broad Temperature Compatibility: Operating range of -30°C to 110°C accommodates various industrial environments when properly lubricated.
