Attention: d1 can deviate from the value quoted. Please enquire if necessary. Different shaft diameters and types on request. The static load capacity has to be decreased by 8 % and the dynamic load capacity by 18 % when using the non corrosion types (HV6) in conjunction with precision steel shafts made of stainless steel. 1)
Shafts cut to special length with chamfered ends. The length tolerance of these shafts corresponds to LJM 20x1500 ESSC2 medium class. The designation for a shaft with 20 mm diameter cut to a length of 1,5 m is, for example, LJM 20x1500 ESSC2.
