A hollow cylinder retention device includes a hollow cylinder and a pair of bearers disposed at opposite ends of the hollow cylinder. Mounted on each of the bearers is a bushing including an actuator for applying a clamping force to a clamping portion of the bearers to securely clamp the hollow cylinder onto a rotatable cylinder shaft. The bushings are arranged on the respective bearings to apply a clamping pressure at a location that is spaced from the bearer points where the hollow cylinder is mounted on the bearers to avoid damage to the bushings and bearers. The hollow cylinder, bearers and bushings are connected to form an integral unit that is easily and quickly mounted and removed from a rotatable shaft.
