Notes about MB....SSQ Series :
An advanced lubrication system delivers up to 300% longer service life. This patented design ensures consistent lubrication in the load zone, even without load reversal, and enables relubrication while the bearing is still under load. These bearings extend operational life in challenging applications and are available in both inch and metric sizes.

Other salient points to be noted :
• All dimensions apply before MoS2 coating and Fracture.
