Sliding Bearing Self-Lubricating Bearing Brass Bushing Plain Bearing
Product Description
SF-1B Bronze 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.
