Shaft diameter d [mm]

20

Version

Standard

Format of linear bushings

– Closed

Series

Super A (with self-alignment feature)

Seal

1 integrated wiper seal

Lubrication

Not lubricated

Maximum dynamic load capacity Cmax [N]

2470

Maximum acceleration rate amax [m/s²]

150

Maximum permissible linear speed vmax [m/s]

3

Note: maximum permissible speed vmax

Speeds of up to 5 m/s possible. Service life is limited by heightened wear to plastic parts. Tests have shown total travel from 50 • 105 m to 100 • 105 m without failure.

Length of linear bushing [mm]

45

Outer diameter D [mm]

32

Permissible ambient temperature (min. ... max.)

-10 °C ... +80 °C

Friction coefficient μ

0.001 ... 0.0025

Note: friction coefficient μ

Friction coefficients of unsealed linear bushings when lubricated with oil. The friction coefficient is lowest under heavy load, but can still be above the specified value even under a low load.

Weight [kg]

Footnote breakaway force

One wiper seal: Multiply value with factor 0.5

Footnote maximum dynamic load capacity Cmax

The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.

Footnote maximum static load capacity C0max

null

Footnote minimum dynamic load capacity Cmin

The dynamic load capacities are based on a total travel of 100,000 m. When based on 50,000 m, the C values in the table are to be multiplied by 1.26.
