Footnote 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.

Footnote 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.

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 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.
