INDRON® TSTN Elastic-plastic alloy is bonded with long-termed lubricative particles, its turbine guide bearings have excellent performances in self-lubrication and water lubrication, which overcome the problem of large starting torques resulting in the use of rubber turbine guide bearings and can effectively protect the shaft/bearing bushing.
