Description High-precision Linear Bushing for moving very heavy loads Radial ball redirection allows numerous rows of balls and extremely high load ratings Heavy-duty guide with degrees of freedom in circumferential direction For applications where other linear guides tend to warp due to imprecise substructures. Very high rigidity Features Extra smooth running Fully sealed or without wiper seals Separate wiper seals optional Relubricatable Hardened and machined steel sleeve Ball retainer made of reinforced PA Balls made of rolling bearing steel Two retaining rings Technical data General technical data Ø d mm 30 40 50 60 80 amax m/s² 50 vmax m/s 2 m kg 0.7 1.4 2.5 4.9 10.4 FR N 8 1) 12 11 1) 16 14 1) 20 16 1) 24 20 1) 30 Breakaway force N 24 32 40 48 60 μ 2) 01 ... 02 Rows of balls 12 Shaft radial clearance h6/bore H6 µm + 21 - 10 + 23 - 13 + 25 - 12 + 26 - 15 + 29 - 15 Shaft radial clearance h6/bore JS6 3) µm + 12 - 20 + 13 - 22 + 14 - 23 + 15 - 26 + 16 - 27 Shaft radial clearance h6/bore K6 3) µm + 6 - 25 + 8 - 28 + 7 - 30 + 8 - 33 + 8 - 36 Operating conditions Permissible ambient temperature (min ... max) -20 °C ... +100 °C 1) Frictional drag for Linear Bushings with separate wiper seals 2) Friction coefficients of unsealed radial Linear Bushings when lubricated with oil. 3) Observe the reduction in service life owing to high preload Load capacities and load moments Ød mm 30 40 50 60 80 C 1) N 8500 13900 20800 29500 54800 C0 1) N 9520 16000 24400 34100 61500 1) The load ratings specified apply for the main direction of loading ρ = 0°. 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 following figure shows load-dependent spring. The diagram applies for installation: Without preload With zero clearance (no preload) for load direction ρ = 0° – 90° and 270° – 360° Radial Linear Bushing rigidity Installing with preload reduces spring. Additional spring in all parts of a linear guide (housing, shaft, shaft support rail) depends on the load direction.
