Abstract
A bearing assembly has an inner ring with an inner diameter configured to receive a shaft. The inner ring has axial slots and at least two radial holes. A collar configured to surround the inner ring is provided. The collar has two radial holes. Each of the collar radial holes is alignable with the at least two inner ring radial holes. Each of the collar radial holes is configured to threadably receive set screws extendable from the collar through the at least two radial holes of the inner ring to engage the shaft. The collar has a radial slot and is adjustable to compress the radial slot to tighten the collar around the inner ring and the inner ring around the shaft. In the alternative, the bearing assembly may be provided with two collars—one for a set screw only configuration and another for a concentric clamping only configuration.
