Суперлинейная втулка Bosch Rexroth KBB-25 [R067202500]

Shaft diameter d [mm]

25

Version

Standard

Format of linear bushings

– Closed

Series

Super B (no self-alignment feature)

Seal

without wiper seals

Lubrication

Not lubricated

Maximum dynamic load capacity Cmax [N]

4820

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]

58

Outer diameter D [mm]

40

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]

0.14

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.

Footnote minimum static load capacity C0min

null

Footnote friction force FR

1. One wiper seal: Multiply value with factor 0.5 2. Frictional drags generated by linear bushings with integrated wiper seals on two sides when not under radial load. The frictional drags depend on speed and lubrication.
