The characteristics of oil free bushing are:
1. Low maintenance frequency;
2. Compared with ball-type linear bearings, oil-free bushings are suitable for low-speed and heavy-load applications;
3. It can also be used under severe conditions of high temperature and low temperature;
4. Compared with linear bearings, the bushing is thinner and saves space;
5. It can be used for linear motion and rotary motion at the same time.
