Speed Guide® s block, SGB of OSGB, is designed to stand double-row deep groove bearing's centrifuga and axial load. The eccentric nut raises the (O)SGB's load and life by prcision  repetition without clearance and is designed to esay for clearance adjustment.

All the Speed Guide realized ZERO clearance in order to keep the precision running.

Two bearings are fixed in one side of shaft and, as the last one (in case of SGB 3 1pcs, in case of SGB4 2pcs, in case of SGB% 3pcs) is eccentric nut, entire bearings do rolling motion by regular contact pressure. Accordingly, when eccentric adjustment isn't right for block, the life will be reduced because of deflection load.

* Suitable eccentric adjustment guaratees long-life
