This design incorporates an internal bearing system that is supplied with grease using automated lubrication system. View Larger Image
Custom 9 This custom stainless steel 3-passage assembly was designed for a customer in the semiconductor industry. This compact design uses both mechanical face seals and DynaSeal™ Teflon seals, and was designed for intermittent 650 rpm duty. View Larger Image		Custom 10 This custom stainless steel 2-passage assembly was designed for a robotic application in a medical manufacturing environment. The shaft end of this assembly was designed to directly mount a specific gripper type. The gripper bolts onto the flange end of the shaft and the opposite end has an extension which is used to drive the assembly. View Larger Image
Custom 11 This 4-port stainless steel custom rotary union was designed for cleanroom service. This assembly operates at 65 rpm and is used to transfer vacuum.This design included several tapped supply ports between each vacuum channel to supply a pad gas to the area between the seals. An 18-circuit integrated electrical slip ring for signal and data transfer was also required for this application.

Custom 13 These small, light weight custom unions are used for a 100 psi air, indexing table application. These simple, inexpensive units were designed to fit the customers existing equipment. Low torque seals and all aluminum construction are two of the features incorporated into this design. View Larger Image		Custom 14 These 2-passage stainless steel and brass custom rotary unions were designed for the car wash industry. Simple yet robust design has proven effective for this 10 rpm, 1100 psi water and chemical transfer application. View Larger Image
Custom 15 This Custom 12-passage rotary union assembly was designed for water, hydraulic fluid and air transfer. The air and water pass through the blue aluminum housing at 100 psi, while the hydraulic is transferred through the black steel housing at 5000 psi. Integrated 24-circuit electrical slipring was included for signal and data transfer. View Larger Image		Custom 16 This 4-passage custom rotary union was designed as a direct replacement for an existing product. The customer required higher hydraulic pressures than the original unit was capable of. This custom union assembly was designed to fit into the same space envelope, yet offers a max. pressure rating of 7500 psi versus 3600 psi. View Larger Image
