JDB-90 maintenance-free bronze solid lubricant oilless guiding bushings are engineered for demanding mold industry applications. These self-lubricating bearings feature centrifugal casting high-strength brass with embedded graphite for superior performance.

• Cost-effective solution with higher crash strength compared to standard bronze graphite bearings
• Solid lubricant activates through frictional heat, creating optimal oil-powder lubrication that protects shafts from wear
• Hardness rating twice that of conventional bronze graphite bushings

• Standard configurations: straight guiding bushings, collar guiding bearings, thrust washers, and slide plates
• Custom designs and specialized materials manufactured to customer specifications

Widely utilized in automotive mold manufacturing, punch mold systems, plastic injection molding equipment, and various industrial mold applications.
