Structural Features & Performance Advantages
Deep Groove Geometry: The optimized raceway design enables efficient handling of radial loads up to 96 lbf dynamic capacity, while also accommodating moderate axial loads in both directions.
Stainless Steel Construction: All components manufactured from 300 series stainless steel provide excellent corrosion resistance and dimensional stability across the operating temperature range of -86 to 230°F.
Precision Engineering: With ABEC1 tolerance class and MC3 radial clearance (0.00008" to 0.0005"), this bearing ensures smooth, quiet operation and minimal vibration.
Shielded Protection: Double metal shields effectively protect against contamination while maintaining low friction operation, contributing to the limiting speed of 54,000 rpm.
Extended Inner Ring: The extended inner ring design facilitates easier mounting and provides additional support for adjacent components.
