SB065AR0 Bearing Product Overview & Core Advantages
The SB065AR0 is a high-performance thin section angular contact ball bearing engineered for precision applications requiring exceptional rigidity and load capacity. Manufactured with stainless steel rings and balls and a brass cage, this single-row bearing is specifically designed to handle combined radial and axial loads simultaneously. Its inch-series dimensions (6.5" bore) and ABEC-1 precision make it ideal for compact, weight-sensitive assemblies where high reliability and corrosion resistance are critical. The 30° contact angle optimizes its axial load carrying capability while maintaining smooth operation.

SB065AR0 Bearing Structural Features & Performance Benefits
Thin Section Design: The Reali-Slim construction provides significant space and weight savings while maintaining structural integrity, making it perfect for compact bearing arrangements where envelope size is constrained.
High Load Capacity: With a radial dynamic load rating of 1132 lbf and axial static load rating of 2840 lbf, this bearing delivers exceptional performance under combined loading conditions. The 30° contact angle efficiently distributes both radial and axial forces.
Precision Engineering: Manufactured to ABEC-1 tolerance standards with tight dimensional controls (bore tolerance: -0.0010" to 0"), ensuring consistent performance and easy installation in precision applications.
Corrosion Resistance: The comprehensive stainless steel construction (rings and balls) provides excellent corrosion resistance, suitable for harsh environments and cleanroom applications.
Temperature Performance: Operating temperature range of -30°C to 110°C allows for use in various environmental conditions while maintaining dimensional stability.
