Two-piece Shaft Collars


The two piece clamp on shaft collars features a split design that allows for easy installation and disassembly in applications where the shaft end is inaccessible. Unlike more traditional one-piece collars, two-piece clamp-on shaft collars can be applied at any point along the shaft, eliminating the need to remove other components for installation, removal, or repair. The clamping power of a two-piece assembly is much greater than other collar assemblies, applying its full seating torque to the shaft, resulting in a more uniform distribution of force around the shaft. These attributes make two piece clamping collar suitable for enhanced holding force and elevated shock-load resistance applications.

The convenience, versatility, and load-bearing strength of two-piece shaft collars make them ideal for use in a wide variety of applications, including:

  • Automation Equipment: Two-piece shaft collars allow for fine control in the positioning and alignment of automation equipment, including pulleys, gears, bearings, and more.
  • Heavy Machinery: Two-piece shaft collars provide direction and mechanical stops for actuators, cylinders, pistons, and other heavy machinery.
  • Laboratory Equipment: Laboratory equipment requires fine stops and spacers for precision operations. Two-piece shaft collars are used on clamps, frames, and tubing to provide precise control adjustments.
  • Medical Equipment: Medical equipment benefits from using precise two-piece shaft collars as guides, spacers, and stops for hospital beds, monitoring equipment, and imaging systems to fit strict industry standards.
  • Optical Instrumentation: Two-piece shaft collars are ideal for precision adjustments and stops for optical equipment in measuring and sensing applications.
  • Power Transmission:  two-piece clamping collar is incorporated into motion control equipment to ensure optimal positioning and accurate stopping points for pistons, cylinders, actuators, and other components.

Quick-Release Two-Piece Clamping Shaft Collars

The quick-release two-piece clamping collar has an adjustable locking lever that can be set to the desired torque and is easily set without tools. They are constructed of black anodized aluminum and feature stainless steel threaded studs to replace standard collar hardware. They come in five different sizes. They are internally threaded for greater support and are designed for non-rotating applications. The clamping ring is designed to be removed without damaging the shaft.

Quick-release clamp rings are a low-cost alternative to traditional clamping options. It features a knurled nut and a cam lever for clamping and is suitable for both horizontal and vertical applications. It’s designed for easy, tool-free use and is ideal for jigs. It also features countersunk mounting holes and an integrated hinge. It’s perfect for holding and securing a variety of tools and materials. It is made of anodized aluminum and can be mounted on 6mm to 75mm shafts. It has a black anodized finish for low RPM applications.

Shaft Collars Application

Shaft collars can be used for almost any application. They are commonly found in gearboxes, electric motors, and transmission applications. They are essential components in most machines. They are easy to install and maintain and can be customized to fit almost any application.
Always consult a professional when selecting a collar. They will help you choose the collar that best suits your needs. The selection process also includes the axis type. A shaft with a large bore will not provide sufficient clamping force.
Solid collars are the most common type. They are usually made of mild steel. They are also available in galvanized versions for even more protection from corrosive elements. They are less expensive than titanium collars but have lower holding power.
