  • HLDB-2Y boundary lubricating bushings also named as SF-2Y are backed with low-carbon steel with porous bronze sintered on it and polymers(POM) imbedded into the bores of the bronze. The steel back provides exceptionally high load carrying capacity, excellent heat dissipation with a pattern of circular indents which should be filled with grease on assembly of the bushing. The circular indents achieve good lubrication between the bushing and its mating axis. This type of bushing has good anti-abrasion and load capalility. The plating coating on the surface is erosion protective. And it is environmental protective as no lead included in the surface polymer POM.

  • HLDB-2Y is widely used on automotive chassis, mine quarrying machines, forging machines, metal melting, casting machines etc. It is especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.
