Crafted from high-quality low-carbon steel, copper powder, and modified POM via specialized processes, this self-lubricating bearing delivers exceptional performance under medium-to-high load and low-speed conditions. The steel base provides robust load-bearing capacity and efficient heat transfer, while the sintered copper powder layer enhances wear resistance and heat dissipation. The modified POM surface incorporates evenly distributed oil pockets for optimal lubricant distribution—initial lubrication is recommended. Designed for long-term, maintenance-free operation in boundary lubrication environments, occasional relubrication significantly extends service life. Ideal for rotary and oscillating motions with high load and low speed.
