Types of linear bearings and shaft available
Linear bearing and shaft combinations remain a widely used method of providing linear guidance. As shafts are often used simply supported, they can be a straightforward and effective method of providing an economical guidance solution.
Shafts and bearings, sometimes called linear bushes, are available from a 5mm to 800mm diameter. Shafts are available in Ck53/Cf53 steel, chromium plated steel along with two grades of corrosion resistant steel. Hollow shaft is also available.
Many different types of linear bearing are available: compact and standard (ISO series 1 and 3); open; closed; self-aligning and clearance adjustable. Bushes can also be supplied in housings known as linear bearing units, further simplifying installation.
