Specifications

Shaft diameter d [mm]	20.0
Version	Corrosion-resistant
Format of linear bushings	– Closed
Series	Segment
Type	Linear bushing
Seal	Without wiper seals
Lubrication	Not lubricated
Maximum dynamic load capacity Cmax [N]	540.0
Maximum acceleration rate amax [m/s²]	150.0
Maximum permissible linear speed vmax [m/s]	3.0
Length of linear bushing [mm]	30.0
Outer diameter D [mm]	30.0
Permissible ambient temperature (min. ... max.)	-10 °C ... +65 °C
Friction coefficient μ	0.001 ... 0.004
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]	0.04
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 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 friction force FR	Frictional drags generated by linear bushings with seals on both ends when not under radial load. This depends on speed and lubrication.
Breakaway force [N]	5
Dimension C js14 [mm]	30
Dimension D [mm]	30
