Notes about B....L 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 72 and above are double fractured (suffix-9L).
• Bore dimensions apply after MoS2 coating. All other dimensions are before coating.
• Ultimate static and impact loads should not exceed 150% of catalog ratings.
