Ball-Bush Block Set 8 D25

The application and characteristics of the modular ball-bush block guides are similar to those of the ball-bearing guide bushes. By separating the sliding carriage into two units, the distance between the points of support on the guides can be selected in accordance with the applied loads. The special profiles of sizes 40x40 and 60x60 (with Line 8 grooves) accommodate both the shaft and the Ball Bushes. The range of sizes and the different shaft diameters are designed to withstand applied loads ranging from 500 to 1500 N at a maximum travelling speed of 2 m/s. The Ball Bushes, which are sealed at both ends, and the high-quality grease filling ensure a long service life, even under difficult operating conditions. It is advisable to carry out calculations to check the load-bearing capacity and service life and to make an allowance for the deflection of the guiding shafts in the case of longer strokes. The Direct-Fastening Set is particularly suitable for connecting the profiles of the ball-bush block guides to other profiles, so that the profiles can be moved and no machining is required.

The Ball-Bush Blocks serve as the guide elements with integral press-fitted recirculating Ball Bushes.

Grooves of Profiles 8 can be used to secure the Bearing Blocks using fastening elements of Line 8.

Direct-Fastening Set 8 provides a particularly easy means of securing Bearing Blocks without need for machining.

Where it is desired to attach to other components they must be drilled and tapped M6.

An individual Ball Bush is unable to absorb any moment. It is therefore always necessary to use two shafts for a guide system, with at least two Ball Bushes being located one after the other on a single shaft. The distances must be appropriate for the moment loads.

The blocks can be pinned in the areas marked (depending on requirements).
