3. Application
Metric Size Dry Sliding Bearings Self Lube Bushings With Long Life Time are widely used in textile machine,food machinery, pharmaceutical machinery etc.
4. Advantages
This dry sliding bearing is designed to improve comfort and reduce maintenance for shock absorbers, hinges, gears, pumps, valves, car seats, vibration dampers and other equipment requiring bearing materials.WHB bushes are produced in a lightweight, compact material with minimum bulk, simplifying shaft assembly. Featuring high-level chemical resistance, shafts can be covered or plated with materials resistant against chemically aggressive liquids, gas or solids, through the application of an additional galvanic layer.Furthermore, by using this type of bushing, vibrations, noise and pollution are significantly reduced.
