Shaft Collars Buying Guide

An essential requirement in any complex industrial mechanism is the requirement to hold various parts together. Be it any industry like power transmission, medicine, automobiles, or a need as simple as holding up a flag pole, shaft collars are ubiquitous in their usage. Shaft collars have various forms and sizes depending on the industry they are used in or the holding capacity they possess.

Why use shaft collars?

There are various uses of shaft collars. The main uses of shaft collars are divided into three broad categories: positioning, limiting, and spacing. As a positioner, shaft collars are used to locate and fasten various components on a shaft. As a limiting device, shaft collars restrict redundant movements of components on a shaft in a reciprocating application. As a spacing device, shaft collars can keep various components at a safe distance from each other, thereby reducing the scope for clashes and collisions.

How to select the ideal shaft collar?

There are various types of shaft collars, depending on how they clamp on to the shaft. The simplest but effective shaft collar is the set-screw collar, which has high holding power. However, the screw used to tighten the collar often causes a small dent on the shaft's surface. The one-piece collar has a high radial clamping capacity but cannot be assembled or disassembled without major disassembly of all the shaft components. The two-piece shaft collar has both high holding power and can be assembled anywhere on the shaft without major disassembly. All these features need to be considered thoroughly for choosing the appropriate shaft collar.

Choosing the right shaft collar material

Shaft collars come in five materials. These are mild steel, type 303 and 316 stainless steel, aluminum, and acetal. They also come in multiple finishes like black oxide or yellow zinc dichromate. In specific industries, the material of the shaft collar needs to be carefully considered. For example, in power transmission, the shaft collar material may be required to have insulating properties, for which an acetal shaft collar is an appropriate choice. The finish of the collar is also essential to consider, as finishes like black oxide prevent rusting.
