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)
