what are differences between Hydraulic Rotary Unions and pneumatic rotary unions? Hydraulic rotary unions and pneumatic rotary unions are both devices used to transfer fluid or gas between stationary and rotating parts of a machine, but they differ in their application, construction,

To seal a rotary union effectively, several key factors should be considered. Here are some common methods and techniques used to achieve a reliable and leak-free seal in rotary unions:Sealing Mechanisms: Rotary unions typically employ one or more sealing mechanisms to prevent fluid leakage.

Rotary unions, also known as rotary joints or swivel joints, are mechanical devices that provide a rotating connection between two fluid or more carrying channels. They are commonly used in various applications, such as rotary indexing tables, machine tool spindles, packaging machinery.....

Hydraulic slip rings are also called hydraulic rotary joints. Hydraulic slip rings are used in low-speed and high-pressure equipment. They are often used in various large-scale machinery.

Jarch has a variety of standard through bole slip rings that can be used directly for wrapping machines, and our rotary joints can be simply customized based on standard slip rings, or connectors design.

The slip rings are small in size, compact in structure, ultra-low wear, no maintenance, and they can meet 360° smooth and unrestricted rotation.

In many years of working developing experiences we have design many kinds of slip ring solutions for cranes in different specifications. Such as our through bore slip rings, flange slip rings, hybrid slip rings..

The kinds of slip rings(connectors) used to transmit precision signals, weak currents, high currents, and high voltages. We can find that they have low torque, low loss and maintenance-free; low electrical noise, and long life in operation. So the through hole slip rings are also called hollow shaft slip rings

The thermocouple slip rings are developed for working in high temperature environment.It plays the role to transmit precise signals, low current, high current and high voltage.

Q: Pls give us a brief information about JARCH.A: We are a professional manufacturer for various kinds of slip rings in many years experiences, a solution provider for rotary planning for many machinery.
