Notes about MB Series :
These bearings are built to handle substantial radial loads even when misalignment occurs. They can also support a moderate amount of thrust load. Featuring a non-separable design with a single split outer ring, they are offered in both open and sealed configurations, and are available in both inch and metric dimensions.

Other salient points to be noted :
• Outer rings of bearings size 160 and above are double fractured (suffix-9L).
• All dimensions apply before MoS2 coating and Fracture.
