Material
Balls, rails and runners roller bearing steel.
Version
Rail and slide galvanised.

Note for ordering
Sold individually.
Note
Partial extension consisting of a fixed guide rail and a movable runner. The slide can move somewhat more than half the length of the rail (S travel). By removing the locking screw, a partial extension with the travel length S is possible to both sides. The total travel is thus 2S .
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).
