Linear bearings and linear bearing units are available as a compact, lightweight, heavy-duty, solid and plain bearing series. The bearings absorb high loads with a relatively low weight and enable linear guides with unlimited travel paths. Each series has very specific properties that make it particularly suitable for certain applications. These can include demands for the compensation of misalignments, for low-friction running, for high accelerations and travel speeds or for a long service life. The expanded and expanded program based on the modular system provides the technically and economically best solution for bearings with shaft guides for every requirement.
