Description For self-supporting, torsionally stiff guides with only one shaft Torque-Resistant Linear Bushings with adjusting screw come set to zero clearance Matching shaft profiles with machined ball guide grooves Precision steel shaft with a ball guide groove for shaft diameters 12 and 16 mm, with two ball guide grooves from shaft diameter 20 mm Features Hardened steel bearing plates Balls made of rolling bearing steel Hardened steel adjusting screw Steel lock nut Ball retainer and outer sleeve made of PA or POM Technical data General technical data Ø d mm 12 16 20 25 30 40 50 amax m/s² 150 vmax m/s 3 m kg 0.026 0.032 0.071 0.13 0.2 0.38 0.62 m (shaft) kg/m 0.89 1.57 2.45 3.8 5.5 9.8 15.3 Operating conditions Permissible ambient temperature (min ... max) -10 °C ... +80 °C Load capacities and load moments Ød mm 12 16 20 25 30 40 50 C 1) N 640 780 1550 3030 3680 6320 9250 C0 1) N 420 530 1050 2180 2790 4350 6470 Mt Nm 2 3.3 12 24 37 86 167 1) The load ratings indicated are minimal values as the load direction cannot always be clearly defined. The load ratings are based on a total travel of 100, 00 m. When based on 50 000 m, the values in the table need to be multiplied by 1.26. Legend Symbol Description Unit Ød Shaft diameters mm amax Maximum acceleration travel m/s2 C Dynamic load capacity N C0 Static load capacity N m Mass kg m (shaft) Weight (shaft) kg/m Mt Dynamic torsional moment load capacity Nm vmax Maximum permissible speed m/s Reduced load capacity with short stroke In case of short stroke, the service life of the shaft is less than that of the torque-resistant Linear Bushing. The dynamic load ratings C in the tables must therefore be multiplied by the factor fs . 1) fs = factor 2) s = movement path Service life, shaft straightness, stabilized installation Definition of dynamic load ratings Dimensions Dimensions Ød mm 12 16 20 25 30 40 50 D 1) mm 22 26 32 40 47 62 75 B mm 32 36 45 58 68 80 100 l mm 400 500 600 M M6x0,5 M10x1 M12x1 M16x1,5 M1 mm 8 12.5 15 20 N1 14.4 mm +0.1 16.4 mm +0.1 21.8 mm +0.1 25.8 mm +0.1 29.7 mm +0.1 37.2 mm +0.1 46.7 mm +0.1 N2 mm 1.3 1.9 2.5 3 1) Recommended installation bore: DK6.
