A heavy duty version of the popular drylin ZLW range of toothed belt linear guides has been introduced by igus. With a maximum stoke length of up to 3m, the new drylin ZLW-20 can handle an axial load of up to 75kg and a radial load capacity of up to 300kg.
Suitable for quick positioning applications, the wide belt drive permits speeds of more than 5m/s, depending on the load. The tension of the polyurethane toothed belt with steel cable is easily adjustable. Underwater applications are also possible with a special belt.
The drylin ZLW-20 offers three shaft centre distances (120, 160 and 200mm). Due to the low profile of the toothed belt axes, even tight installations spaces are accommodated. The support blocks, rails and carriages are available either made of light-weight aluminium or stainless steel. The stainless steel system is particularly well-suited for applications in the food industry.
The use of iglidur J linear bearings on moving parts makes the linear system self-lubricating and maintenance free. The absence of lubricant also makes it insensitive to dust and dirt, as particles will not stick to the moving parts.
