Concentric & Eccentric Adaptor Bushings
Used for mounting guide wheels, the adaptor bushings are available as concentric or eccentric versions
Note
Eccentric bushings are used opposite concentric bushings to provide a simple and effective means of adjusting the free play of the system. Also, since the circumference of the wheels is greater at the major diameter than the minor diameter, there is a constant wiping action on the track which gives a self-cleaning effect.
Track System - Hepco
An economical method of obtaining precision linear motion for all types of mechanical applications. A low friction accurate slide can be assembled quickly and inexpensively without the aid of costly machine tools. Guide wheels and track have an operating temperature range of -20 to +120°C.
