Established in 1998, China Xiaowei Bearing Co., Ltd. is a high-tech enterprise specializing in rotary coupling manufacturer and design many kinds of bearings. We have a modernized staffs of tech research and fog machine development, ISO9001 certificated, and manufacturing adopts advanced domestic and foreign standards such as GB, API, JIS, DIN, BS, NF and ANSI. Our custom rotary couplings are exported to countries and regions in Europe(UK, France, Italy, Germany), North America(USA, Canda), the Middle East and Southeast Asia.

Deublin Offers a full range of Rotary Unions with Ball Bearings. Some are sealed and do not require any lubrication while others have a gease nipple and require periodic lubrication. Capacities from 50 to 1K Nm. (442 to 8,850 lb-in).Short overall length. Integrated coupling. Bearingless. +/-15 bit resolution. 10 kHz samle rate. +/-5 VDC output. Able to conduct water, hot oil, steam, chemicals, and air media, HPMC Series MultiPort Rotary Union accommodate 2–8 ports, each of which is individually sealed to eliminate crosstalk between channels. Device provides rotating seal between fluids and revolving roll or drum. Once clamped, slotted rotating disk remains in-place regardless of rotation. Operating parameters range up to 250°F, 5880 psi, and 180 rpm, and port sizes range from 1/8–1¼ in. Each port of the MultiPort Rotary Union is individually sealed eliminating crosstalk between channels. As the end-user clamps the slotted rotating disk into his fixture the body of the MultiPort remains in-place regardless of rotation. All MultiPort Rotary Unions are constructed of steel and are nickel plated as standard. The HPMC Series can accommodate two to eight port configurations. Operating parameters range up to 250°F, 5880 psi, and 180 RPM. Port sizes range from 1/8" to 1-1/4".
