FRW156 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its precision construction. The single row of 10 precision balls, manufactured from Chrome Steel, ensures smooth operation and low noise. The stainless steel cage provides excellent guidance and durability at high rotational speeds, directly contributing to the high limiting speed. The MC3 radial internal clearance is optimized for a wide range of operating conditions and fits. The extended inner ring with a flange enhances rigidity and simplifies assembly, making the bearing exceptionally reliable in demanding applications.
