Heavy Duty Linear Motion Technology
Featured Product from Modern Linear Incorporated
From wood processing to oil fields and transport systems to jigs & fixtures many linear motion applications involve vibration, heavy, and/or shock loads, in addition to environmental issues like contamination, temperature variations and corrosion. Some conditions like temperature and corrosion can be addressed with material or lubrication options, others are best addressed with linear components inherently designed to handle these conditions.
Guide rollers, by design, can handle many of these demands. Modern Linear v-groove rollers integrate 2 rows of angular contact ball bearings. The balls are separated from each other and the 2 row complements are contained between the inner and outer races. The balls and bearing races are protected by shields or seals. All contamination is kept out of the ball path, unlike recirculating ball guides like ball bushings and profile rail guides, where the shaft or rail acts like the inner race. This design is susceptible to contamination and generally needs to be protected in rugged applications.
