SF-2 boundary lubrication bushings are based on composite material with 3 firmly bonded layers: Steel as backing, sintered bronze spherical powder as interlayer and modified POM as lining layer. The bushes fit well for low speed. Heavy duty and normal temperature and saves cost and prolongs working life when replacing normal all copper sleeves. The bushings are widely applied in auto chassis, forging machine, metallurgical and mining machine, civil engineering, power station, strip-rolling industries etc. We can make all sizes and types of this bushes, also by clients requests.

The speficication of the bushes as follows:
Load capacity: 140N/mm2;
Temperature limit: -40~+130;
Speed limit: 2.5M/s;
Friction clef: 0.05-0.25;
PV limit(dry): 2.8N/mm2*m/s;
PV limit(oil): 22N/mm2*m/s.
