RW2-5zz Bearing Structural Features & Performance Benefits
Optimized Load Capacity: With a radial dynamic load rating of 107 lbf and static load rating of 32 lbf, this bearing delivers reliable performance in demanding applications. The deep groove raceway design efficiently distributes radial loads across six precision balls.
Precision Engineering: Manufactured to ABEC1 tolerance class with MC3 radial internal clearance (0.00008" to 0.0005"), ensuring consistent performance and smooth operation. The stainless steel cage maintains ball alignment and reduces friction.
Material Excellence: Constructed from chrome steel rings and balls with 300 series stainless steel shields, providing excellent durability and corrosion resistance. The bearing operates effectively across a wide temperature range from -86 to 230 °F.
Speed Performance: Capable of operating at limiting speeds up to 60,000 rpm, making it suitable for high-speed applications while maintaining stability and reliability.
