Linear bearings comprise a standardised range of ball bushings and housings or units that enable the simple configuration of linear guide solutions to suit almost any application. Linear bearings are used with a precision cylindrical linear shaft allowing unlimited stroke length.
The linear bushing range covers linear ball bearings and plain bearings, available in open, closed, clearance-adjustable and self-aligning designs. Typically four linear ball bearings or units with two shafts and four shaft support blocks are required to build a linear slide system.
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.
Widely used throughout industry and in many different kinds of application including:
