The sliding shoes consist of a polyamide.

The guide system consists mainly of rails, guide shoes and rails.

Guide system mainly consists of guide rail, guide shoe and guide rail.

A non-skid surface may be provided on the inner surface of the guide shoes.

The pivot part of the guide shoes is preferably generally cylindrical.

For wider gaps, it is recommended to add lateral guide pads.

The reamer (10) is provided with three guide pads (28, 30, 32) in the cutting part (14).

The crossheads (8) are guided in the transverse direction of the engine by means of guide shoes (15) journalled on a crosshead pin (13) and sliding along guide planes (18).

The sliding blocks (8) are held, at that side thereof which faces away from the running surface (10), by means of a retraction plate (14).

Furthermore, it is also possible to use sliding surfaces and guiding pad instead of rolling surfaces (6) and pulleys (10).

The pistons (7) are supported, via sliding blocks (8), on a running surface (10) which is inclined relative to the cylinder drum axis (6).

The guide rails or slides projecting beyond the vertical supporting frame of the press unit can rotate both horizontally and vertically in order to reduce the bulk of the press.

The drill head for boring the deep hole is formed by fixing a cutting edge (2) to the tip face side of a head body (1) and guide pads (3) and (4) to the tip outer peripheral side of the head body (1).

To this end, the sliding shoes (6) are prefabricated as separate components and placed in the pressure mould in which the aluminium basic body (5) is manufactured by a pressure casting process.

This measuring device has a signal transducer (27) which generates an amplified voltage signal as the guide shoes, which act as signal generators, move over it.
