Commodity: Partial type bearings
Origin: China, Germany, Japan
Price: Negotiate
Specification: Order
Warranty: 02 years
artial type bearings is a kind of water lubricating composite material which is made from a high strength sythetic fiber and high wear resistant special engineering plastic strengthened high molecular material as its friction surface layer, and the composite material and steel base are intergraded with each other through vacuum soldering process. Type of bearing is applied widely in heavy industry as follow: It has been used in hydro-generator, large pump, turbin in electrical station, mechanical equipment in hydropower project (supporting of arc gate, wheel part in plat gate)...ect
Advantage:
- It has strong affinity to water, anti - sediment and excellence wear-resistant performance.
- Low friction, smal power consumption and it can save more than 15% other bearing
- Long life
