Lovejoy 350 Series Shaft Locking Device, Split Ring, 24 mm Shaft Diameter x 28mm Outer Diameter of Shaft Locking Device, 62.3 ft-lb Maximum Transmissible Torque

This Lovejoy SLD 350 Series internal shaft locking device is a locking element for connecting a hub to a shaft in power transmission applications. It has an internal and external tapered ring, and when axial force is exerted, pressure is generated on the shaft and hub bore for a frictional connection. It is a split ring for applications requiring larger tolerances and/or higher torques. There are no moving parts, so there is no wear, and the device can be reused. No stops are needed, so a boss or hub can be locked at any point along a shaft. This locking element is suitable for the connection of gear wheels, chain sprockets, levers, cams, belt pulleys, brake drums, flywheels, couplings, and clutches, among others.Shaft collars are ring-shaped devices primarily used to secure components onto shafts. They also serve as locators, mechanical stops, and spacers between other components. The two basic types of shaft collars are clamping (or split) collars, which come in one- or two-piece designs, and setscrew collars. In both types, one or more screws hold the collars in place on the shaft. In setscrew collars, screws are tightened through the collar until they press directly against the shaft, and in clamping collars, screws are tightened to uniformly compress the collar around the shaft without impinging or marring it. Whereas setscrew collars and one-piece clamping collars must be installed by sliding the collar over the end of the shaft, two-piece clamping collars separate into two halves and can be installed between components on the shaft. Shaft collars are made from a wide range of materials including zinc-plated steel, aluminum, nylon, and neoprene. Found in nearly every type of machinery and industry, shaft collars are used in applications including gearbox assemblies, motor bases, machine tools, drive shafts, agricultural implements, medical equipment, and paper and steel mill equipment.Lovejoy manufactures flexible couplings, universal joints, variable speed drives, and other transmission and mechanical power products. The company, founded in 1900, is headquartered in Downers Grove, IL.
