Specifications

  • Low-cost Linear Bushing for high requirements
  • Steel bearing plates with machined ball guide grooves and optimized ball lead-in chamfers for outstandingly smooth travel and a long service life
  • Without self-alignment feature for transferring lower tipping force along the axial direction
  • Open Linear Bushing on fully supported shafts for applications where other linear guides tend to warp due to imprecise substructures.
  • High travel speed (5 m/s)

Operating conditions Operating conditions
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. ) 3 m/s
FR (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. ) 1.50 N
m (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. ) 0,001 ... 0,0025
