Rexroth R067212540 super linear bushing

KBB-25-D

$63.06 Limited stock only available on quotation

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)
