ASSEMBLY PROCEDURE BEFORE START ASSEMBLY against the mounting and reference shoulder. They should then be bolted down by tightening up progressively, starting from one end and working to the other. 4) Parallelism of the V-tracks of the rails (ΔA and ΔB ) should be checked. The tolerance must be within the tolerance of the linear bearings (page 14). When this has been done, the slide element in question is now ready for assembly. PM linear bearings are precision components; they have to be handled with meticulous care. To achieve a perfect linear bearing, please pay due attention to the...

Compact, reliable and suitable for high loads. Linear bearings type RNG in size 4 and 6 mm are a further development on the RSDE type. This results in advantages as significantly higher load ratings and stiffness but also more compact installation dimensions by optimizing the internal geometry of the groove. Roller cages type KRE are available in POM and PEEK material. STRUCTURE AND FEATURES The construction exists of two pairs linear bearings; one pair consists of two similar 90° V-groove, through-hardened and precision ground, fitted with a crossed roller cage in-between (KRE cage:...
