New smaller version of DryLin ZLW belt-driven actuator

Igus is extending its range of linear belt drive actuators with the addition of a smaller version of its DryLin ZLW drive. The DryLin ZLW-06-30 weighs just 1kg and measures 1m in length. It is suitable for handling lightweight loads and high speeds and is practically silent. Nevertheless, despite its low weight, it is also extremely robust.

Igus says the original DryLin ZLW belt-driven positioning unit was the first on the market to be fitted with polymer plain bearings. It is maintenance-free, lightweight and can reach speeds of up to 2m/s. The sliding elements are made of Igus iglidur J polymer and the bearings are injection moulded from iglidur L250. Housing components are manufactured sturdy plastic and the profile is hard-coated aluminium. All connecting screws are made of stainless steel.

A second version of the actuator uses ball bearings for the deflection shafts, which makes higher traverse speeds are possible. Apart from these bearings, this axis is also completely maintenance- and lubrication-free due to the iglidur high-performance polymer bearings used.

The new ZLW-06-30 model was developed as a result of enquiries from industries contending with extremely confined installation spaces, which required some simple changes to enable them to position small loads within cramped conditions.

Matthew Aldridge, Bearings Product Director at Igus UK, says: "We believe that there is not a linear drive system on the market that comes close to this in terms of performance and price."
