Engineering plastic bearings with high wear resistance and light weight provide the possibility for lightweight design of bicycles; Maintenance-free bearings for bicycle pedals, wear-resistant plastic bearings for shock absorbers, bicycle transmissions, rear suspension walls, handbrakes, and high-performance engineering plastic bearings have been adopted by many bicycle design engineers for their excellent performance and low cost advantages. Non lubrication has a longer service life and reduces costs. Immediately, metal sliding and bearings are being replaced to explore the huge potential for cost reduction and weight reduction. Maintenance free, self-lubricating, high and low temperature resistance, wear resistance, impurity resistance, dirt resistance, low noise, quiet operation, high load characteristics - these functional characteristics are very suitable for bicycle equipment. Renimoshen provides polymer engineering plastic sliding bushings, bearings, various shafts, linear guides, etc. with these characteristics.
