Rotary Feedthrough DN40CF with precision scale

Product code: RD40SC-XXXX-YYYY

The magnetically driven rotary feedthrough RD40SC can be used wherever a smooth rotary motion has to be performed. Due to its high torque of 5Nm, considerable force can be transferred to any in-vacuum gear if necessary. For maximum durability, all ball bearings are DicroniteTM (W-disulfide) dry lube coated. A laser etched 360 deg scale with a vernier allows for 0.1 deg readout precision. Options include motorization, with or without encoder.

Standard retracted shaft length: 50mm (customizable)
Standard airside length: 103mm (customizable)
The airside length of the RD40SC can be customized for easier access and handling depending on the layout of your system.
Please contact us if you need other dimensions.
