NSK Bearings 6308DDU 6308-2RS 40X90X23MM Double Rubber Seal Bearings Deep Groove

Deep-groove geometry for high speeds and supporting both radial and axial loads
Single-row bearing for supporting radial loads
Shields on both sides of the bearing to keep lubricant in and contaminants out
Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision
Pressed steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise
