The designation for an LZBU quadro-linear table with a shaft length of, for instance, 1 200 mm LZBU …-2LS x 1200. Delivered as a kit of parts. Recommended maximal shaft length. On demand longer shaft lengths are available. The appropiate length tolerances of these shafts are according to DIN 7168 coarse series. Suitable Screws with internal hexagon according to DIN 912 / ISO 4762. Valid only for even loading of all four LBC … A linear ball bearings. On delivery the deviation of the shaft must be considered and possibly the load rating revised. Units fitted with LBCR linear ball bearings are not designed for relubrication and are not self-aligning.
