| zz | Double shielded (both sides) | Effective contaminant exclusion while maintaining low friction |
FRW3zz Bearing Structural Features & Performance Benefits
Extended Inner Ring Design: The extended inner ring (0.2273" width) facilitates easier installation and provides superior axial location capability, making it ideal for applications requiring precise positioning.
Optimized Load Capacity: With a dynamic radial load rating of 249 lbf and static rating of 88 lbf, this bearing delivers reliable performance in various load conditions. The deep groove raceway design enables handling of combined radial and moderate axial loads.
High-Speed Capability: Featuring a stainless steel cage and precision-ground chrome steel components, the bearing achieves a limiting speed of 110,000 rpm, suitable for high-speed applications.
Controlled Internal Clearance: The MC3 radial internal clearance (0.00008" to 0.0005") ensures optimal performance across a wide temperature range (-86 to 230 °F), accommodating thermal expansion while maintaining smooth operation.
