The Slide Units Series QCTF - QCBF have been designed to be used in applications where space is limited. Regarding the bearings, the Slide Units are available in two versions, one with double sintered bronze bushes (Mod. QCTF) and the other with double linear ball bearings (Mod. QCBF). The QCTF version would normally be selected when the side loads applied to the slide unit are high. Mod. QCBF is suitable for fast cycles (less side load) and higher precision.

The end cushioning is available in three different variants: A. fixed mechanical cushion (standard), B. with two shock absorbers located on the body and C. with one shock absorber located central on the rear flange. Accordingly, the variant B and C are suitable for handling of higher mass forces and / or when it is necessary to adjust the stroke.
