Item description/product images

DescriptionMaterial:Balls, rails and slides roller bearing steel.Version:Rail and slide electro zinc-plated.
Tracks inductively hardened.
Balls hardened.
Note:Partial extension consisting of a fixed guide rail and a movable slider. The slide can move somewhat more than half the length of the rail (C travel). By removing the locking screw, a partial extension with the travel length C is possible to both sides. The total travel is thus 2C.
This compact and simple construction allows very high load ratings.
The maximum traversing speed is 0.8 m/s.

Application temperature -30 °C to +170 °C.
On request:Other lengths (pitch 80 mm).
