Linear Units

The linear carriage T20 of the drylin W series makes switching from ball guides to sliding linear guides even easier.

igus presents design study for automatic and compact cable retraction system

Whether in an industrial environment or in a coffee machine, in order to maximize the service life of a linear guide and to keep the required drive energy low, it is important to reduce friction and wear as much as possible. igus, a motion plastics specialist, has now achieved a breakthrough in tribological plastics: With iglidur E3, igus has developed a new sliding material that has a friction coefficient that is up to 40 percent better and thus opens up design flexibility in linear technology for users for the first time from the classic 2:1 Rule expanded to 3:1. The new iglidur E3 sliding material is available from Treotham.

When determining if an application calls for a lead or ball screw, your decision should be guided through evaluating the inherent advantages and disadvantages of each. This evaluation process can have a significant impact on the performance and economic benefits of linear motion projects. The first step comes from understanding how they differ. Both ball and lead screws use threaded rods to convert from rotary to linear motion. Ball screws, as the name would imply, use recirculating ball bearings to minimize friction. Lead screws, by contrast, rely on a low coefficient of friction from sliding surfaces.
