Frequently Asked Questions (FAQs)

1. What is a shaft collar clamp used for?

A shaft collar clamp, also known as a shaft collar, is used to locate, space, and secure components on a shaft. It fastens axially or radially to a shaft and serves various purposes such as spacing, limiting stroke, retaining sprocket hubs, bearings, and protecting the shaft.

2. What are the different types of shaft collars?

There are several types of shaft collars available, including set screw, one-piece split, two-piece split, balanced, and hinged collars. The one-piece split, two-piece split, balanced, and hinged collars fall under the clamp-type collar category. Each type of collar has its own advantages and uses.

3. Which type of shaft collar is more secure?

Threaded shaft collars offer the greatest axially holding power and are suitable for use with shock loads. They are commonly available in one and two-piece clamp styles. Threaded bore collars are popular due to their secure holding capability and versatility.

4. Where are shaft collars used?

Shaft collars are used in a wide range of machinery applications. They can be found in various industries and are often used to hold bearings and sprockets on shafts, position components in motor and gearbox assemblies, and act as mechanical stops.

5. How does a shaft collar work?

A shaft collar is a ring-shaped device made of metal or plastic that clamps around a shaft. It is commonly used in power transmission applications to hold motor components, gear assemblies, sprockets, bearings, and other parts in place. The collar ensures that the components are securely positioned and can sometimes facilitate their movement.

6. How do you hold a shaft in place?

To hold a shaft in place, a shaft collar is fitted over the shaft component, and a set screw is tightened to secure the collar in place. This type of collar is cost-effective but relies on the frictional force applied by the set screw to maintain its position on the shaft.
