Work support
Information
Work support provides solid adjustable support 
to parts and Work support will work in most 
applications where part distortion, deformation, 
and chatter conditions occur. They can eliminate 
or reduces most of the problems caused by part 
movement during machining. 
Available in two variants, Threaded body and Flange 
body Work support.


•	Work support capacity should be equal to or greater than 1.5 times clamping force plus machining force
•	Wiper seals reduce contamination of dust for the long run of Work support
•	Special coating on the cylinder body helps to prevent rusting and scratching
Specifications
•	Minimum operating pressure: 25 Bar
•	Maximum operating pressure: 70 Bar
•	Operating temperature: 10 - 70 °C
