Item description/product images

DescriptionMaterial:Bearing block and carriage aluminium alloy, anodised.
Guide columns stainless steel, ground.
Spindle stainless steel, rolled thread.
Guide bearing maintenance-free.Version:Radial play on guide < 0.02 mm.
No axial backlash.
Spindle self-locking, with additional lock.Note:Due to the practically play-free guides and absolutely play-free spindle, loosening or clamping of the spindle is not required during adjustments.
Scale graduation is 5 or 10 increments, 1 increment is equal to 0.1 mm travel.
Within the respective sizes, the positioning stages can be easily combined using the modular principle.Special features:
