SY20 Boundary Lubricating Bushing

Product Details

SY20 is designed for marginal lubricating bushing. It is backed with copper-plated steel with porous bronze sintered on it and polymers(POM) embedded into the bores of the bronze. The steel back provides the products with high-quality low-carbon steel. Oil dents stamped on the surface of the polymer can achieve good lubrication between the bushing and its mating axis. It is of good anti-abrasion and load capacity. The plating coating on the surface is erosion-protective. It is environmentally protective as no lead is included in the surface polymer POM. Products of SY20 series are widely used on automotive chassis, forging machines, mine quarrying machines, metal melting and casting machines, and in water irrigating and steel rolling industries.
