Carbon Steel Oil Free Self-lubricating Bushing Dry Running Bushing
Carbon Steel Oilless Self-lubricating Bushing is with low carbon steel as the backing, sintered bronze as medial layer,mixed PTFE with fibers as self-lubricating layer. 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.
Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication.
Organizational materials:
1. PTFE with fibers 0.01-0.03mm
2. Sintered bronze powder 0.2-0.35mm
3. Low carbon steel 0.7-2.3mm
4. Cu or Tin coating 0.008
The actual thickness of metallographic structure is negotiatiable.
Application and features:
Our Oilless Bushings are applied to metallurgy extensively, automobile, mine, petroleum, such various kinds of machinery as rolling mill, chemical industry, electrical machinery, shipping, printing, plastic machinery,office equipment,health and fitness facilities, light industry and machinery, irrigation works, hydraulic pressure machinery, locomotive, rotate, slip, etc.
1. No oil lubrication or less oil lubrication, which is suitable for the occasions where it is impossible to be lubricated or difficult to be lubricated, and can be used without maintenance or less maintenance;
2. Good wear resistance, small friction coefficient and long service life;
3. Can be used from - 195 ℃ to + 280 ℃;
4. Good alignment performance, low noise and no pollution;
5. Thin wall structure with light weight can reduce mechanical volume;
6. The transfer film can be formed during operation, which can protect the grinding axis without the phenomenon of nibbling;
7. Low hardness of the grinding shaft, which can be used without tempering treatment, thus reducing the processing difficulty of related parts;
8. No water absorption, oil absorption, small thermal expansion coefficient, good heat dissipation and stable size;
9. The steel back can be plated with a variety of metals, so it can be used in corrosive media without rust.
