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.
