Self-Lubricating Bearings Manufacturer | One-Stop Sliding Bearing Solutions from China
We are a factory-direct manufacturer specializing in the R&D and production of self-lubricating bearings and oilless bushings. With years of experience in the sliding bearing industry, we operate complete CNC production lines, an in-house materials laboratory and a full quality inspection system. We supply machinery manufacturers worldwide with graphite plugged bronze bushings, composite bushings, bimetal bushings, guide bushings, self-lubricating wear plates and related components.
Why Choose Self-Lubricating Bushings?
Conventional bushings need continuous greasing. In high temperatures, dust, underwater operation or low-speed heavy-load conditions, lubrication often fails, causing rapid wear, seizing and high maintenance costs.
Our maintenance-free bushings use high-strength brass or bronze with embedded solid graphite lubricant, or steel-backed composite materials with a PTFE sliding layer. No external oil supply is needed, so they run reliably in oil-free and low-lubrication environments, with low friction, excellent wear resistance and strong anti-seizing performance, even in harsh working conditions.
