Description Low-cost Linear Bushing for general requirements Small outer dimensions and highly compact construction Stainless steel for the medical, chemistry and food industries: Segmental load bearing plates comprising 1.4037 balls made from 1.3541 Reduced radial clearance for applications where minimal-clearance bearings with an H7 bore are desired Initial lubrication with Dynalub 510 Features High dynamic load rating and long service life due to hardened segmental load-bearing plates with ball conformity in the track. Simple mounting: Just press on – no additional securing needed High travel speed (5 m/s) Integrated wiper seals, external seals or no wiper seals Integrated metal holding rings about 0.1 mm larger than outer diameter (shaft diameters 12 to 50) for secure fit in housing bore Many pockets acting as lubricant reservoirs for extended lubrication intervals or lubrication for life Pockets collect any dirt that may have worked its way in to prevent the Linear Bushing from jamming.

The frictional drags depend on speed and lubrication.

When based on 50 000 m, the values in the table need to be multiplied by 1.26. Legend Symbol Description Unit Ød Shaft diameters mm amax Maximum acceleration travel m/s2 Cmax Maximum dynamic load rating N Cmin Minimum dynamic load rating N C0max Maximum static load rating N C0min Minimum static load rating N FR Friction force N m Mass kg vmax Maximum permissible speed m/s Effect of load direction on load rating The listed load ratings should be chosen depending on installation in minimum or maximum position and should be based on the calculations. 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 short stroke, the service life of the shafts is less than that of Linear Bushings. The load ratings C specified in the tables must therefore be multiplied
