Shaft collars are integral to the proper functioning of virtually every mechanical device or assembly. Simple shaft collars consist of a metal or plastic collar and set screws that apply pressure around a shaft. They serve as an attachment point between a shaft and a component and as mechanical stops. Because they are used in a wide range of applications and industries, manufacturers have developed a variety of shaft collar designs and configurations, including the two-piece shaft collar.
Two-piece shaft collars are easy to install on shafts with inaccessible ends because they can be completely disassembled and reassembled around the shaft. This functionality allows them to be tightened more than single-piece collars creating greater compressive holding force for enhanced load-bearing capabilities.
Two-piece shaft collars feature a split design that allows for easy installation and disassembly in applications where the shaft end is inaccessible. Unlike more traditional one-piece collars, two-piece shaft collars can be applied at any point along the shaft, eliminating the need to remove other components for installation, removal, or repair. The clamping power of a two-piece assembly is much greater than other collar assemblies, applying its full seating torque to the shaft which results in a more uniform distribution of force around the shaft. These attributes make two-piece shaft collars suitable for applications that require enhanced holding force and elevated shock-load resistance.
The convenience, versatility, and load-bearing strength of two-piece shaft collars make them ideal for use in a wide variety of applications, including:
Two-piece shaft collars offer many benefits over other collar designs. Advantages include:
Hinge shaft collars are a variant of the two-piece shaft collar, with a hinge on one side of the collar connecting the two pieces. Rather than fastening the collar on both sides, you can install it around the shaft by opening and closing it at the hinge. The hinge design offers the same easy disassembly and reassembly capabilities as two-piece shaft collars, but with no loose parts or fasteners.
This allows them to be installed much more quickly, making them ideal for quick installations in time-sensitive applications and harsh conditions.
