Grip Tight Adapter Mount Bearings

View in Online Catalog

The Grip Tight mounted ball bearing is the maintenance-friendly solution for all of your ball bearing application needs, capable of performing critical functions in many operations. Grip Tight mounted ball bearings offer a unique method of shaft attachment via a thin wall tapered adapter sleeve and locknut design. Because of this system, bearing assemblies may be installed and removed from a shaft easily. 360 degrees of concentric grip on the shaft for the entire length-through-bore of the bearing means Grip Tight provides a tight press fit with no shaft damage, even on commercial grade shafting.

Easy-on / Easy-of
During mounting, the collar/inner ring system locks the tapered adapter sleeve under the bearing and onto the shaft. To dismount, the built in bearing puller pulls the bearing off the adapter and pushes the adapter in the opposite direction (out from under the bearing).
