Pipe Bushings for Shaft Collars


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.
