• CLI-1 dry bushing and self lubricating bearings are also known as SF-1 or DU bearings;
• CLI-1 dry bushing and self lubricating bearings are with low carbon steel as the backing,
sintered bronze as medial layer, mixed PTFE with fibers as self-lubricating layer.
• It is suitable for dry running with low coefficient of friction, low wear rate,good sliding characteristics, the transfer film created will protect the mating metal surface.
• It is also suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling.
• CLI-1 series dry bushing and self lubricating bearings are also performing well with lubrication.

APPLICATIONS
1. Suitable for oilless or few grease working conditions;
2. Long maintenance-free ; Long operating life due to low friction;
4. Low vibration,low noise and non-pollution in operation;
5. Thin wall thickness & low weight for the machine with compact design;
6. Low hardness of mating shaft can be mated,so the shafts processing is easy;
7. PTFE film is transfered to the mating shaft, to protect the mating metal Surface, also improve running properties;
8. Lower absorption of water ,heat dissipation,and reduced swelling,to keep the exact sizes;
9. Copper or Tin plated in outer Surface , for good anit-corrosion. |
