Product Description
Sintered Guide Bushing Straight Type - Self Lubricating Bearings High Load
High-performance sintered guide bushings designed for demanding industrial applications requiring self-lubrication and exceptional load capacity.
Product Overview
The oilless self-lubricating bearing is a composite bearing featuring a steel backing with wear-resistant porous materials. The specialized wear-resistant layer is created by sintering copper alloy powder and graphite-based solid lubricant on a metal base at high temperatures, followed by special oil-containing treatment.
Solid lubricant is uniformly distributed throughout the alloy layer, forming a durable lubricant film from the beginning of sliding. With low shear strength, this film adheres firmly to the bearing surface without cracking under ultra-high static loads, eliminating crawling phenomena during microscopic movements. The metal base provides exceptional mechanical strength and dimensional stability, delivering superior friction and wear characteristics.
Key Features
- Uniform solid lubricant dispersion enables friction resistance from any direction with excellent fretting wear performance
- Engineering machinery bearing that operates completely without oil lubrication
- High load capacity, exceptional wear resistance, and superior speed characteristics
- Available in standard goods and custom plate specifications for secondary processing
Advanced DNB-#200 Technology
DERNORE has developed the innovative DNB-#200 oilless self-lubricating bearing to replace traditional DNB-#50 types. This advanced product delivers equivalent wear resistance while offering enhanced dust, corrosion, and impact resistance. It performs exceptionally in various industries including injection molding machines, tire molds, and engineering machinery such as excavators.
The DNB-#200 bearing demonstrates superior lubricating properties compared to DNB-#50 types. With complete surface lubrication, it maintains performance in challenging conditions including reciprocating motion, rocking motion, and frequent starts, delivering significantly improved wear resistance.
