Sliding Bearing Self-Lubricating Bearing Brass Bushing Plain Bearing

SF-1BBronze Backed with PTFE Dry Bearings (Corrosion Resistance) Material: bronze+PTFE Bronze backing, provides exceptionally high load carrying capacity, excellent heat dissipation and very good corrosion resistance. This material meets the demanding criteria for long life and trouble-free performance with or without lubricant, of high safety factor even. The bronze backing provides a high corrosion resistance, anti magnetic properties and a good thermal conductivity, The bearings are particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition. The typical applications covered Steel metallurgy industry such as bushes for roller grooves of successive casting machines, cement grouting pumps and screw conveyors for cement and so on. Tech.
