Flange-Mount Shaft Collars
Three tapped counterbored holes and three unthreaded holes provide mounting flexibility. Collars clamp evenly around the shaft to create a strong, mar-free hold. To use, slide onto your shaft and tighten the clamping screws to secure.
Collars with keyway have a standard ANSI keyway for use with keyed shafts, keys, and key stock.
Black-oxide steel collars are stronger than aluminum and stainless steel collars. They have some corrosion resistance. Aluminum collars are lightweight and have good corrosion resistance. 303 stainless steel collars have excellent corrosion resistance.
Optional flange extensions extend the flange OD of the collars to handle larger components. All are machinable and weldable.

Easy-Access Flange-Mounted Shaft Supports
Carbon Steel
Stainless Steel and Aluminum
A removable collar allows access to the shaft without unbolting the flange. For use with light to medium loads where shaft alignment is not critical, these supports allow you to hold linear shafts perpendicular to the mounting surface. Secure the shaft by tightening the clamping screw. These supports are machined to have flat, square surfaces, so they can be used to align other supports and parts in your system.
Aluminum shaft supports are lightweight and resist corrosion. Stainless steel shaft supports resist corrosion better than aluminum supports.

Pipe Bushings for Shaft Collars
One Flange
Two Flanges
Sized specifically to adapt standard shaft collars to pipe, these bushings create a tight fit. They're nylon, so they won't break if your pipe expands or contracts.
One-flange bushings can be installed when a shaft collar is already loosely assembled around the pipe. Because there is only one flange, the collar could slip off over time.
Two-flange bushings prevent shaft collars from sliding off even in high-vibration environments. You’ll need to disassemble your shaft collar to install it around these bushings.
