Page 1936 | 3.8 Adjusting, Moving with Guides, Spindles and Ball Rollers The outer slide is made of a press formed block of anodized Aluminum extrusion which is usually the moving part. As a standard there is usually one outer slide size for each outside slide length on which the connecting sets GN 900.2 and mounting plates GN 900.4 and rotary plates GN 900.5 can be mounted. Special lengths can be supplied. The inner slide is also made of a press formed block of ano- dized Aluminum extrusion which is the carrier. The guides are made of two high grade shafts in stainless steel. High load ratings and favourable friction values is achieved by the anodized hard guide surfaces. The length of the inner slide is determined by the length of the outer slide by adding the stroke. The backlash free drive unit consists of an end plate and a preloaded stainless steel spindle, ball bearing mounted, and a preloaded plastic nut (temperature resistant from - 20 °C up to + 80 °C). The thread pitches are: Slide size b = 30: 0,5 mm Slide sizes b = 50, 80, 120: 1,0 mm Die Positionierung erfolgt mit Hilfe einer Skala (ein Teil- strich = 0,05 mm Verstellweg), die auf „0“ gesetzt werden kann.

On the latter, the adjustable slide unit is mounted on a base plate from the operator’s side. Connecting sets GN 900.2 consist of four rails. With the latter, two adjustable slide units are combined to form an adjustable assembly X – Y (or Y – Z). Connecting sets GN 900.3 consist of two plates. With the latter two adjustable slide units combined to form an adjust- able assembly X-Z (or Y-Z). If this slide has to be parallel to the reference axis this is achieved by using an additional plate (Type P). Adjustable Slide Units Features
