Electric belt-drive rodless axis with a bearing structure made up of anodized extruded aluminium.
The typical V-Lock dovetail is fitted to the extruded side (opposite the slide), which facilitates the fixing using QS elements; at both sides there are grooves for the installation of the bracket fixing the proximity switch (optional), which detects the position of the slide.
The slide is moved by the polyurethane toothed belt with steel cables.
The parabolic profile of the belt tooth makes it possible to maintain a high efficiency level, contain the level of noise and vibration from transmission gears.
The axis is available in two sizes, BK-1 and BK-2.
The slide interface is characterised by the V-Lock profile complete with M5 threaded holes, pinholes and key seats, which guarantees numerous fixing options (not present in the BK-2 heavy XL version).
All the versions have in-line steel guides that are housed in an extruded structure. The BK-1 size is available in two variants: the “Medium” uses castors running along hardened and tempered guides with double-row ball bearings, and the more performing “Heavy” version consists of a guiding system with a rail and ball recirculation pads.
The BK-2 size is available in two variants, both with rail and ball recirculation pads, the “Heavy” type has two pads and the “Heavy XL” has a longer slide and four pads. In the BK-2 size, the belt has a special profile that, when coupled with the extruded profile, prevents any dirt or foreign bodies from entering inside. BRUSHLESS and STEPPING motors are available, with optional motor brake and/or built-in encoder.
The versions with a BRUSHLESS motor can be equipped with a toothed belt speed reducer or a planetary gearbox.
The electric axis can be ordered without drive or, on request, with modules for interfacing with motors available from the trade.
The motors can be installed on all the four hubs of the heads, and their position can be changed at any time, without requiring any additional operation.
Various accessory kits for the installation of a gantry system starting from one axis are also available.
