The Dodge® 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 deg 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.
