Aluminum Shaft Collars

Aluminum Shaft Collars

Product Description

Our lightweight, high-precision single-split clamping shaft collars are engineered for high-speed machinery and weight-sensitive assemblies. The one-piece design compresses uniformly across the shaft's circumference, minimizing slippage while protecting the precision-ground surface from damage.
 

Precision & Material Design
Manufactured from high-strength aluminum alloy, these collars feature a sandblasted and anodized finish for enhanced durability and wear resistance. Adjustments can be made efficiently utilizing a single high-tensile cap screw.
 

Applications
This series is well-suited for linear guide end stops, robotic arm joints, and medical automation systems.

We offer our shaft collars in a wide range of materials-including lightweight aluminum, robust carbon steel, and corrosion-resistant 304 stainless steel-to match your working environment. If you need assistance selecting the correct model, material, or surface finish for your project, please feel free to reach out to our team at any time.

Operating Principle: Radial Compression Clamping
One-piece clamping collars secure shafts by utilizing the mechanics of radial compression.
The Structure: The collar is engineered as a solid ring featuring a single radial slit on one side. A high-tensile socket-head cap screw is positioned perpendicularly to bridge this gap.
The Clamping Action: Applying torque to the single cap screw draws the two sides of the slit closer together, decreasing the inner diameter of the collar.
The Physics: Rather than concentrating force on a localized point (as with set-screw designs), the inner circumference of the collar applies uniform radial pressure. This distributes the clamping force across the shaft's surface area, significantly increasing the static friction contact area without damaging the shaft.
