  • HLDB-1B bushing also named as SF-1B, meets the demanding criteria for long life and trouble-free performance with or without lubricant or of high safety factor. The bronze backing provides a high corrosion resistance, anti-magnetic properties and a good thermal conductivity. This type of bushing is particularly appropriate for high temperature environment where no oil is efficient and the machine must be under successive long period working condition.
