Rotary joint for machine tool fixtures

Rotary joints, also known as rotary joints or hydraulic slip rings, are critical fluid dynamic sealing devices used in machine tool fixtures. Its core function is to efficiently and leak free transport of fluid media (such as hydraulic oil, coolant, compressed air, etc.) from stationary pipelines to rotating or reciprocating machine tool fixture components. In modern CNC machining and automated production lines, rotary joints are the core components that enable automatic clamping, loosening, internal cooling, and chip blowing of fixtures, directly determining machining accuracy, production efficiency, and equipment operation stability.

The hydraulic rotary joint effectively solves the problem of difficult oil supply from hydraulic hoses and fixed piping to the rotating worktable of the machining center.
For example, when selecting the 4-circuit type, it can be used to control 4 single acting oil cylinders or 2 double acting oil cylinders respectively
According to the continuous improvement of domestic machine tool customers, the requirements for four axis fixtures are also increasing. Based on the proportion of customer feedback information, we have selected and designed several four axis rotating joints tailored for customers. We hope that you can communicate with our technical personnel about the usage parameters before selection. Thank you for your cooperation!
Product Structure Features:
Low starting torque
By using a special seal with low resistance, the sliding resistance is controlled to a small level, achieving low torque during startup.
Excellent sealing performance and durability
The sealing sliding surface has been ground, hard coated with inscriptions, and subjected to ultra precision machining, exhibiting excellent sealing performance and durability.
