Shaft Collars（Side Hole Machining：2-Hole）

Shaft collars are essential components in mechanical and power transmission systems, widely used across various industries for securing and positioning components on a shaft. These versatile devices come in several types, including set screw collars, one-piece and two-piece clamp collars, and hinged collars, each designed to offer specific benefits for different applications. Made from durable materials such as steel, stainless steel, aluminum, and plastic, shaft collars provide reliable performance in holding bearings, sprockets, and other components in place. Their applications range from serving as mechanical stops in motor and gearbox assemblies to acting as load-bearing faces in complex machinery setups. With their ability to offer precise positioning and robust holding power, shaft collars are indispensable for engineers and designers looking to ensure the smooth operation and maintenance of their machinery

FAQ Shaft Collars

Question: What is a shaft collar?: Answer: A shaft collar, sometimes called a shaft clamp, shaft stop, or shaft collar clamp, is a simple yet crucial component used to locate and secure objects onto a rotating shaft. It's a machined ring-shaped fastener with a smooth or threaded bore. A setscrew tightens against the shaft, creating a frictional force that holds the collar in place.
Question: What are the different types of shaft collars?: Answer: Here are some common types of shaft collars.
• Set screw collars: These are the most basic and economical type. They have one or two setscrews that tighten against the shaft for a secure hold.
• One-piece collars: These collars are pre-assembled, making them quick and easy to install. They offer a lower profile than set screw collars.
• Clamp collars: These collars use a lever mechanism to clamp onto the shaft, providing a strong hold without needing tools. Ideal for frequent adjustments.
• Take-up collars: These collars have a split design that allows for easy adjustment of the shaft position. Useful for applications requiring precise alignment.
• Threaded collars: These collars have internal threads that screw directly onto a threaded shaft, offering a very secure connection.
Question: How to choose the right shaft collar?: Answer: When selecting a shaft collar, consider these factors:
• Shaft diameter: Choose a collar with a bore size that closely matches your shaft diameter.
• Application requirements: Consider the needed holding force, adjustability needs, and ease of installation.
• Material: Select a material compatible with your shaft material and application environment. Common materials include steel, stainless steel, and aluminum.
• Number of setscrews: One or two setscrews provide different holding strengths and ease of adjustment.
Question: What is the difference between set screw and clamp shaft collars?: Answer: • Set Screw Collars: These use screws to secure the collar to the shaft. They are suitable for applications with low torque but may damage the shaft surface if over-tightened.
• Clamp Collars: These provide a more secure grip without marring the shaft. They are ideal for high-torque applications and allow for easy adjustments.
Question: What Surface Treatments Are Available for Shaft Collars?: Answer: To enhance performance and durability, shaft collars can feature:
• Black oxide coating for corrosion resistance
• Zinc plating for extended lifespan
• Electroless nickel plating for improved wear resistance
