YUKEN CR Series Rotary Hydraulic Cylinders
Product Introduction
YUKEN CR Series is high-precision vane-type double-acting hydraulic rotary actuators, converting hydraulic pressure into stable angular rotary torque output. Adopts integrated vane structure, compact body, large torque density, accurate angle positioning and low backlash. Compliant with JIS & ISO standards, widely used for 90°/180° rotary clamping, valve switching, manipulator rotation, fixture overturning and automatic angle control systems.

A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through
a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
A: Sure. Show us the drawing, we will quote for you soonest.
A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.
