Leadscrews
Non-ball leadscrews can self-lock and prevent back driving, without an external brake, unlike traditional ballscrews for vertical applications.
Features & benefits
- Sliding friction between nut and screw converts rotary input motion to linear output motion, for accuracy comparable to ground ballscrews
- No need for hardening; easily machined
- Proprietary coating eliminates need for external lubrication and maintenance
- Manufactured from 303 stainless steel with precision rolling process
- Standard diameters from ⅛ to 15/16 in.; standard leads from 0.02 to 3 in.

Ballscrews
Long-lead ballscrews with a rotating nut design provide precise positioning and serve as compact, ready-to-use, and easily integrated solutions for linear-actuation applications requiring high speeds, low noise, and long strokes.
Features & benefits
-
Design allows drive motor to move with the nut to reduce inertia, require less power, and achieve linear speeds to 110 m/min.
-
Integrated nut minimizes inertia and critical-speed problems
-
Series SLT features nut with axial play; series BLT offers backlash elimination
-
Diameters range from 25 to 50 mm; leads range from 20 to 50 mm
-
Options include double protection wipers and brush wipers in cylindrical and flanged nut configurations and long-lead screws
