Modular belt-driven slides are easy to integrate

Item is introducing two new internally-guided belt-driven linear slides that are available up to 6m long. Based on extruded aluminium profiles of 60x60 and 80x80mm cross-section they feature 6mm and 8mm T-slots, respectively, for attaching additional components or integrating into more complex structures. These slim units have no finger-traps, the only moving part being a carriage plate no wider than the outer section, and the drive belt that covers the slot, effectively sealing it against dirt or dust ingress.

The bearing design consists of double-ball-bearing rollers running on 10mm or 14mm shafts, respectively, allowing speeds of up to 10m/s to be achieved. The specially constructed AT timing-belt ensures an accuracy of +/-0.1mm and features a fabric covering that, in combination with a stainless-steel backing strip on the return run, reduces noise and frictional losses.

Integration of limit switches is extremely simple: the moving carriage assembly has a contact plate that passes over inductive proximity switches. These switches are another specially designed product that fit into the grooves of the profile and their position can therefore be adjusted before finally being clamped in position. Any cables can be hidden in the groove behind a cover profile and up to four switches can be incorporated into each slide.

Routine maintenance is very easy. Lubrication is effected by accessing the internal felt wipers from the side of the unit. Though normally not required after the initial setting, belt tensioning is achieved by adjusting a calibrated tensioning axle and the eccentric rollers are also easily accessible.

Bolt-on drive sets are available for mounting motors. Synchronising sets can be used when running a parallel pair of slides together, the linking shaft being contained within a neat cover if desired.

All parts required to build the KLE units are stocked in the Machine Building Systems factory in the UK. Bespoke units can therefore be built to tight lead times if necessary.
