Low carbon steel + Copper powder + PTFE/Fiber

Suitable for work areas where lubrication is impossible or difficult to achieve, featuring excellent wear resistance, low friction coefficient, and extended service life; exhibits superior break-in performance, low noise, pollution-free operation, and strong corrosion resistance; the transfer film formed during operation protects mating shafts, preventing shaft seizure; low machining requirements for mating shafts reduce user processing costs; simultaneously, the LM-40's specialized wear-resistant layer design delivers superior wear resistance and an extremely low friction coefficient compared to other dry-type bearings under lubrication conditions.
