Safety Warning

Full Product Description

Parker 4900-Series Ball Slides are mechanically simple linear bearings, designed and assembled to provide exceptional smoothness and linear straight line accuracy. This is achieved by the ball and rod linear bearing design. The ball and rod bearings on Parker ball slides consist of two rows of hardened steel balls, each preloaded between four hardened ground steel rods. This design provides ultra-smooth, extremely low-friction motion by reducing the contact area between the balls and the ways. Additionally, this design provides extremely good straight line and flatness accuracy. All Parker ball bearing slides incorporate 440C hardened stainless steel ball and rods to ensure corrosion resistance and long life. Both the top and base aluminum mounting surfaces are precision machined to ensure flatness. Available in both Imperial and metric mounting configurations. Ball slides are functionally much more reliable than simple dovetail slides, since there is no direct sliding contact of the top and bottom members. Ball slides eliminate the rapid wear problems, regular lubrication requirements, and “stiction” (skipping and jumping caused by the increased force needed to initiate movement) characteristic of dovetail slides.

The 4900 Series ball bearing linear slides are the largest of the ball bearing slides. Two linear rows of bearings (one located on each side of the base), support the carriage and provide smooth, accurate, linear guidance.
