SHAFT COLLARS
A shaft collar, also known as a clamping collar, is a component used in the industrial sector to clamp and secure elements on a shaft. These collars are placed around the shaft providing a secure and reliable hold.
Applications
INDUSTRY
- Industrial automation: Essential in robotic systems, automated conveyor systems and assembly equipment. Used to clamp components and tools on robot axes, ensuring precise positioning and reliable torque transmission.
- Packing: Used to clamp packaging machine components, such as rollers, knives and discs, on the corresponding shafts. This ensures precise alignment and smooth operation of the machines.
- Food industry: Ideal for mixing equipment, agitators and conveyors. Used to fasten propellers, paddles and other components on shafts, ensuring efficient and safe movement of materials and/or products.
- Pharmaceutical industry: Used in filling machines, laboratory equipment and diagnostic systems. Perfect for clamping components on shafts, ensuring safe and precise clamping in critical environments.
USES
- Component fastening: Clamp and secure components on a shaft, such as pulleys, sprockets, gears, couplings and drive shafts. Provide a firm hold, preventing slippage or unwanted rotation of components during operation.
- Position adjustment: Used to adjust the position of components on a shaft. By sliding the collar along the shaft, the relative position of the component can be altered to achieve the proper alignment, correct spacing or adjustment needed on a machine or equipment.
- Slip prevention: prevent slippage of components on a shaft, especially in applications where there are significant forces or torsional loads. Provide a secure hold that keeps components in place, preventing unwanted movement and ensuring reliable equipment performance.
- Torque transmission: In power transmission systems, shaft collars are used to transmit torque from the shaft to the components mounted on it. Provide a solid and secure connection that allows efficient transfer of power and motion between the shaft and the connected components.
- Accurate alignment: Help maintain proper and consistent alignment, which is essential to ensure smooth and efficient operation of machinery and equipment.

Example No.000301
In this application we see an assembly that corresponds
to a component clamping mechanism.
The product passes through the belt to the inspection
point where it is held by moving the crank, which is
mounted on a linear shaft and secured by means of a
shaft collar.
Types
Standard
With Clamping Lever
For Bearing Mounting
With Urethane
With Side Holes
D-cut
Two Flats
Threaded
With Keyway
- Standard: Cylindrical, and ring-shaped device designed to slide onto a shaft and secure various components in place. Standard shaft collars are typically made from materials like steel, stainless steel, aluminum, or plastic, and they come in various sizes to accommodate different shaft diameters.
- With Clamping Lever: Also known as a lever handle shaft collar or quick-release shaft collar, is a specialized type of shaft collar that incorporates a lever mechanism for easy and tool-free installation, adjustment, and removal.
- For Bearing Mounting: These collars are used to secure and properly position bearings, ensuring they are firmly held in place on the shaft and preventing axial movement during operation.
- With Urethane: Engineered to provide specific advantages, such as vibration dampening, shock absorption, and enhanced grip on the shaft.
- With Side Holes: Specialized type of shaft collar that features drilled holes on its sides. These holes are designed to allow for additional mounting, attachment, or positioning options beyond the standard bore used for shaft attachment.
- D-Cut: Has a flat side, resembling the shape of the letter “D,” and a curved side. This design allows the collar to be mounted onto a shaft with a flat or keyed surface, providing anti-rotation and precise positioning capabilities.
- Two Flats: Referred to as a “double-split shaft collar” or simply a “two-flat shaft collar,” is a specialized type of shaft collar that features two opposing flat sides on its interior bore. A two flats shaft collar is designed to provide secure clamping and anti-rotation for a shaft with flat surfaces on two sides.
- Threaded: Used in various applications where precise positioning, locking, or clamping is required.
- With Keyway: Ideal for applications where it’s essential to transmit torque and prevent axial movement of a component along a shaft.
Advantages and Features
Standard Collar Shafts:
Secure a component, such as a bearing or a pulley, onto a shaft. Prevent axial movement, ensuring that the component stays in its intended position on the shaft. Standard shaft collars are relatively simple to install and do not require specialized tools or extensive training.
Carbon Steel are available with finishes in Black Oxide and Electroless Nickel
Stainless steel shaft collars provide additional resistance to corrosion and can be used in food and pharma industries.
Aluminum alloy shaft collars are available with clear or black anodized finish if needed to improve lifespan.
Two Piece Clamp-On:
Designed with a split configuration, consisting of two halves that can be easily separated and reassembled around the shaft. This design simplifies installation and removal without the need to disassemble other components on the shaft.
Two Piece Clamp-On collar shafts are available in more variability of materials; carbon steel, stainless steel, aluminum, polyacetal and MC nylon.
With Urethane:
The collar shafts whit urethane are made of a base material; carbon steel or stainless steel, and with a cover of urethane in one of the sides. The base material can have a finish that increase the resistance to wear, tear or corrosion.
The urethane side helps to improve vibration dampening, shock absorption, noise reduction, grip, resistance to chemicals and helps protecting the components increasing the durability of the whole collar.
Similar to the standard collar shaft, it is simple to install using inserts or screws.
With Clamp Lever:
Allows for tool-free installation and adjustment of the collar. This means you can quickly and easily secure or release the collar without the need for additional tools, reducing downtime and simplifying maintenance.
The lever handle provides a convenient way to adjust the collar’s position on the shaft. You can move the collar along the shaft or release it with a simple flip of the lever, making it ideal for applications where frequent adjustments are necessary.
It’s available in materials like carbon steel and stainless steel. You can increase the protection of the collar shaft made of carbon steel by adding a finish of black oxide or electroless nickel.
