SELF-LUBRICATING SLEEVE STEEL BEARING MADE IN CHINA | FORMING MACHINE TOOLS

VIIPLUS has carved a niche as China’s premier exporter of steel-based self-lubricating sleeve bearings, specializing in heavy industrial applications like forming machine tools. With 57% of its products shipped globally, VIIPLUS combines cost efficiency with engineering excellence to compete on the world stage.

Why Forming Machine Tools Demand Self-Lubricating Bearings

• High cyclic loads: Repeated impact forces during metal shaping.

• Heat generation: Friction from continuous operation.

• Contamination risks: Dust, metal shavings, and lubricant degradation.

• Embedded solid lubricants (PTFE, graphite) for zero external lubrication.

• High load capacity (up to 250 MPa).

• Corrosion and wear resistance in harsh environments.
