Winners Speed Guides
Winners Speed Guide linear motion guides -- SG Type, SG Wide Type and OSG Type families with manufacturer rail, block and seal part numbers, dimensions and load ratings.
Speed Guide architecture
Winners Speed Guide products use life-lubricated adjustable Gothic Arch double-angular contact bearing block carriages on patented pressed-in shaft base rails. An eccentric nut allows preload adjustment for stiffness versus friction in high-speed, high-acceleration linear motion systems such as pick-and-place, semiconductor handling and automated assembly.

Common questions
SG Wide Type (SGW models, SGWR rails, SGWB blocks) uses wider base plate dimensions than standard SG Type (SG models, SGR rails, SGB blocks) to resist high lateral moments. Compare base width and flat width W1 in the catalogue tables on this page.
OSG Type is the opened-type Winners Speed Guide family (OSGR rails, OSGB blocks, OSG models) optimized for weight reduction and linear accuracy. Models OSG-20 through OSG-40 are listed in the OSG catalogue table on this page.
