Abstract:
The Two Axis Track Roller is in the form of two sealed bearings mounted to a single stud which allows the device to carry loads in two dimensional axis. In this way the device can carry a load along a track as well as guide along a track wall. When used in pairs the device can be "pre-loaded" which allows for precise guiding of linear motion. The conventional bearing used provide internal balls and rollers which ride on their internal precision ground and hardened surfaces. The external bearing surfaces thus can ride on non hardened track surfaces whose precision is dictated only by the application requirements. Since the bearings are sealed the bearing balls and rollers do not come in contact with environmental contaminants so bearing life is increased.
