LHS170-2Y series 2 channels hydraulic rotary joint hydraulic slip ring
This is a capsule unit with a 170 mm body, carrying 2 circuits across a continuously rotating joint. The stator stays with the frame and the rotor turns with the machine, so the wiring on the moving side keeps its connection through unlimited 360° rotation.
LHS170-2Y at a Glance
This is a capsule unit with a 170 mm body, carrying 2 circuits across a continuously rotating joint. The stator stays with the frame and the rotor turns with the machine, so the wiring on the moving side keeps its connection through unlimited 360° rotation.
- Ø170 mm
- -30℃~+120℃
What This Model Gives the Machine
Unlimited rotation without cable wind-up
The rotating side keeps its electrical connection through continuous 360° turning, so the machine never has to stop and unwind.
Maintenance-free contact system
Precious metal contact pairs are designed to run without lubrication or servicing for the rated life, so there is nothing to schedule on this axis.
Fits a 170 mm interface
The 170 mm envelope keeps the joint inside the space the assembly already has, so the surrounding design does not have to change.
Stable transmission under vibration
The contact geometry is designed so that shock and vibration do not translate into resistance variation on the signal rings.
Backed by a 12 month warranty
12 months from date of sale; free repair or replacement for quality problems not caused by human damage
Engineers Who Specify This Part
Machine builders working on rotary tables, wrapping and filling machines, drilling and subsea tools, antenna positioners and process equipment.
Application scenarios
- Any continuously rotating axis
Three Failures It Removes
Failure 1
A twisted harness inside a rotating assembly chafes against the housing until an intermittent fault appears that nobody can reproduce.
Failure 2
A rotating joint that is not sealed for its environment lets dust or wash water reach the contact surfaces, and the symptom looks like an electrical fault.
Failure 3
Fitting a rotating connector after the mechanical design is frozen usually means cutting into the envelope somewhere it was not planned.

Operating environment

How the Unit Is Built and Checked
Machining runs on the in-house CNC centre across roughly 6000 m² of research and production space, and assembly is done by the production team in Jiujiang.
Before despatch each unit is checked for insulation resistance, insulation strength, dynamic resistance variation and functional signal performance, using the test equipment and procedures held under the ISO 9001 and GJB9001C quality systems.
Certifications
- ISO 9001
- GJB9001C
- GB/T 19001-2008 / ISO 9001:2008
What Can Be Changed on This Build

How It Compares With the Other Formats
A through bore unit keeps the centre of the axis clear but needs more radial space and a flange. Choose the capsule format when nothing has to pass through the middle and the envelope is the binding constraint.
Fitting and Commissioning
Mount the stator, not the load
Fix the stator to the frame through the flange or the anti-rotation arm and couple the rotor to the rotating part. The slip ring must never be used as a bearing — the machine's own bearing carries the load.
Respect the lead route
Leave a service loop at both ends and keep the bend radius above the cable's own minimum. Most field failures start at a lead that was pulled straight.
Separate power and signal runs
Route the power leads and the signal leads apart from each other after they leave the unit, and ground the shield at one end only.
Commission at low speed
Turn the assembly by hand first, check continuity on every circuit, then run up to speed and confirm the signal quality before the machine goes into production.

About LHS170-2Y
How many circuits does LHS170-2 have?
This build has 2 circuits. The ring count can be changed on a customised build — send the number of single wires that have to cross the joint.
What does the 170 mm in the model number refer to?
It is the outside diameter of the body. In LHS170-2 the digits after the series letters give that dimension in millimetres, and the number after the dash is the circuit count.
How long does delivery take?
Standard products ship in 7–15 days. Simple customised products take 10–20 days and complex customised products take 15–40 days. The delivery port is Jiujiang, China Mainland.
Can this model be modified for my machine?
Yes. Send the rotating speed, the installation type and size, the circuit count, the voltage and current per ring, the signal types and their parameters, the operating temperature and the IP requirement, and the unit is redesigned around them.
