This depends on speed and lubrication. 2) 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.

If the load direction is clearly defined and the Linear Bushings can be installed in maximum position, the load ratings Cmax. (dynamic load rating) and C0 max (static load rating) can be used. If aligned installation is not possible or the load direction is not defined, the minimum load ratings must be used. Reduced load capacity with short stroke In case of a short stroke, the service life of the shaft is less than that of the segmental Linear Bushing. The load ratings C specified in the tables must therefore be multiplied by the factor f.s .
