12 best clamp on shaft collars

Clamp-on shaft collars are mechanical devices used in various industrial and mechanical applications, particularly within the field of power transmission products. These collars are designed to secure and position components on a shaft, typically to prevent axial movement or to maintain a specific spacing between components. Here are some key points about clamp-on shaft collars:

Design and Function: Clamp-on shaft collars consist of a split circular ring with a threaded bore and one or more screws or clamping mechanisms. They are designed to be easily installed and adjusted without the need for disassembling other components of the machinery.
Materials: These collars are typically constructed from various materials, including steel, stainless steel, aluminum, and plastic. The choice of material depends on the specific application and environmental factors.
Applications: Clamp-on shaft collars are used in a wide range of industrial applications, including:
- Power Transmission: They are commonly used to secure pulleys, sprockets, and gears to shafts, ensuring efficient power transmission.
- Positioning: In robotics and automation, clamp-on shaft collars are used to precisely position components like sensors, encoders, and rollers on shafts.
- Guide Rails: In conveyor systems and linear motion setups, they help maintain the alignment and spacing of guide rails and support components.
- Safety Stops: They can be used as safety stops to prevent over-travel of machine parts.
Adjustability: One of the key advantages of clamp-on shaft collars is their adjustability. They can be easily repositioned along the shaft and securely tightened to accommodate changes in the assembly or to fine-tune the positioning of components.
Variety: Clamp-on shaft collars come in various sizes and styles to accommodate different shaft diameters and application requirements.Some may have one or two clamping screws, while others have more, providing extra holding power and security.
Installation: To install a clamp-on shaft collar, you typically slide it onto the shaft, position it as needed, and then tighten the screws or clamping mechanism. This securely locks the collar in place.
Maintenance: Regular inspection and maintenance are important to ensure that clamp-on shaft collars remain securely fastened and do not loosen over time due to vibration or other factors.

In summary, clamp-on shaft collars are essential components in power transmission systems and various industrial applications. They provide a convenient and adjustable means of securing and positioning components on shafts, contributing to the efficient and reliable operation of machinery and equipment.

Question:	Needing to clamp down thin wall tubing over heavier wall. thin wall is 2 1/8" o.d. should i buy the 2" to gain some clamping force? or

Question:	Do you have a 3” bore size
Answer:	Largest we have is 2.5 inches, sorry.
