SF-2X Marginal lubrication bushing is based on 3 layers of solid composite materials, with steel backing, sintered bronze spherical powder as the intermediate layer, modified POM (polyoxymethylene) as the inner liner. The products is suitable for low-speed, heavy-duty, room temperature, cost savings and longer life when replacing ordinary copper sleeves. It is widely used in automotive chassis, forging presses, metallurgical and mining machinery, civil engineering, power plants, rolling steel and other industries.
2. Product Technical Data:
Friction coef(μ)：0.05~0.25 PV
limit (oil)：22N/mm2 .m/s
3. Product details
---POM (polyformaldehyde) with lead,0.3~0.5mm
---Porous bronze (CuSn8Zn3), 0.2~0.3mm
--Steel backing (ST12, or DC01), 0.4~2.2mm

◆ Good load carrying capacity and abrasion resistance.
◆ It has high load capacity and low speed, with rotation, oscillation or frequent stop-start motion.three. Under boundary lubrication conditions, oil-free operation is performed for a long time, and working time is longer under oil and grease lubrication intervals.
◆ POM is thicker and can be processed.
◆ Can be widely used in automotive chassis, forging press metallurgy, civil engineering, power plants, rolling steel and other industries.
