HD Seriesrotary jointalso known asCooling water rotary jointsThe HD type rotary joint is a series of products specially designed for cooling applications, with the advantages of small size, light weight and low friction torque. It has the advantages of small size, light weight, small friction torque, etc. HD type rotary joints are unidirectional flow type, adopting high-quality bearing joints with reliable quality, and the individual joints can be easily and smoothly withstanding the rated load. It is mainly used for supplying cooling water, hydraulic oil or compressed air to one end of rotating rollers, drums, cylinders, etc., and discharging from the opposite end. Widely used in iron making machinery roller, dense plastic cooling traction roller, calender roller for paper making and other equipments, mainly used in tanning, paper making, textile, metallurgy and other industries cooling system.
