Frequently Asked Questions (FAQs)

1. What size are shaft collar screws?

Shaft collar screws come in three sizes: 5/8", 3/4", and 1". These steel set screw shaft collars can be customized with different bores and plating options. They are used to ensure that the shaft remains securely in place within the bearing.

2. What is the purpose of a shaft collar?

The purpose of a shaft collar is to hold various components in place, such as motor components, gear assemblies, sprockets, bearings, and other parts. It helps locate and space these components properly and limit their movement, ensuring the smooth operation of the machinery.

3. Which screw is used to fasten pulleys collars on shaft?

Solid shaft collars are generally fastened with one setscrew. The setscrew has a knurled end that bites into the shaft, providing a secure hold. These solid shaft collars are commonly used due to their design and cost-effectiveness.

4. What are the different types of shaft collars?

There are various types of shaft collars, including set screw, one-piece split, two-piece split, balanced, and hinged collars. One-piece split, two-piece split, balanced, and hinged collars are all clamp-type collars and offer different features and applications.

5. What is the difference between a set screw and a clamp shaft?

Set screw shaft collars use a setscrew to hold the collar in place, which can potentially mar the shaft. On the other hand, clamp-style collars use compressive forces to lock the collar onto the shaft. Clamp-style collars are easily adjustable, removable, and work well on any shaft without marring.

6. How do you install a shaft collar?

To install a shaft collar: 1. Use the collars as they are received. 2. Clean the bore of the collar. 3. Apply a thin coat of light oil to the shaft. 4. Place the collar in the desired location on the shaft and tighten it until slight resistance is felt. 5. For two-piece collars, maintain the gap between the two halves during installation.

7. How do you secure a pulley to a shaft?

To secure a pulley to a shaft, tighten the mounting screws, which will draw the tapered surfaces of the bushing and pulley hub together. This creates a wedging action between the bushing, pulley, and drive shaft, ensuring a secure attachment.
