The S062 front labyrinth sleeve is a dedicated sealing part for Warman AH and ST series slurry pumps. Adopting a precision labyrinth groove structure, it is installed at the inner shaft end of the bearing housing to effectively block slurry, sediment and dust from entering the bearing cavity, while retaining grease and preventing leakage. Made of high-strength wear-resistant material with high coaxiality, it features strong erosion and corrosion resistance, stable operation and low vibration. It greatly protects bearings and extends service life. With standard dimensions for direct interchangeable installation, it is easy to maintain and ideal for harsh working conditions such as mining, coal washing and tailings disposal.
