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.

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 a) M6 x 0.75 lube port for cross-roller bearing, L3 thread depth b) Concentricity tolerance c) Recommended installation d) Fixing screw e) Lube nipple Dimensions Ød 1) mm 20 25 30 40 Ød ‒ actual mm 18.2 23 28 37.4 D h7 mm 40 50 61 76 D1 h7 mm 66 78 100 120 D2 mm 34 40 47 62 D3 mm 34 42 52 64 D4 mm 56 68 86 104 L 60 mm -0.2 70 mm -0.3 80 mm -0.3 100 mm -0.3 L1 mm 13 16 17 20 L1 13 mm 16 mm 17 mm 20 mm L2 mm 12 13 17 23 L3 mm 5.2 6.4 6.8 8 S mm 4.5 6.6 9 S1 M4 M5 M6 t mm 7 8 10 Fixing screw M4 M6 M8 1) Actual shaft diameter varies Project planning information Life expectancy calculation Mounting Installation Radial clearance: approx. ± 5 μm Align the tracks and wiper seals when inserting the shaft and make sure they are not skewed! Attention: Do not loosen the flange connection (cross-roller bearing). Tighten the fastening bolts in phases until the table value is reached. General mounting instructions Commissioning Initial lubrication Linear bushings do not come with initial lubrication. Grease the Linear Bushings before use. Service lif
