Movie shows plain linear bearings in high-speed tests

Over the years, engineers at igus have encountered incidents where traditional linear slides have not held up to regular use at high speeds; this is because they wear, cause damage by sediment build-up and have a high coefficient of friction - all of which is why igus developed the DryLin range of plain linear bearings and linear guides.

igus DryLin plain linear bearings can run at speeds of up to 20m/s due to a low coefficient of friction, high load capacity and no lubrication requirements; grease and oil are one of the main factors in slowing down a linear slide, as this collects debris that slows the machinery and eventually causes downtime.

The DryLin range uses proven plastic technology to provide a robust and reliable plain linear bearing system that runs virtually maintenance-free; bearings can run on round shaft, monorail systems, low-profile guides and modular double-rail units. DryLin has more recently evolved to include driven modules, either by trapezoidal leadscrews or, for high-speed applications, belt drives. The running lifetime, and other critical technical points, can be calculated precisely using the online tools found at, as well as 2D and 3D CAD models.

DryLin plain bearings are subjected to extensive testing and development to ensure that they consistently offer the optimum characteristics for customers and their applications. Follow the link to see a movie of igus DryLin plain linear bearings and guides under test.
