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
