Product Spotlight: Ball/Leadscrews

Leadscrew assemblies

Line of leadscrew assemblies includes acme leadscrews, advanced coatings, and anti-backlash nuts to minimize lost motion while maximizing system stiffness.

Features & benefits

  • Diameters range from ⅛ to ⅝ in. with leads as fine as 0.012 in. and fast leads to 1.25 in.

  • Rolled from precision ground 303 stainless steel

  • Come with Black Ice coating, a PTFE process that eliminates flaking

  • Technical catalog highlights leadscrew assemblies and anti-backlash nuts

Roller pinion system

Precision roller pinion system is an alternative to precision ballscrews, converting rotary motion into precise, backlash-free linear motion.

Features & benefits

  • Bearing-supported rollers mesh with optimized tooth profiles, achieving smooth, trouble-free motion

  • Accurate positioning speeds to 660 m/min

  • Low friction design minimizes heat and wear

  • Segments of rack allow the system to be configured for any length

Rolled ballscrews

Grade C10 metric rolled ballscrews come in low-dust raise greased versions in threaded outer diameter 10, lead 4 sizes.

Features & benefits

  • Induction-hardened for rigidity and long performance

  • 100 to 318 mm lengths available; configurable in 1-mm increments

  • Carburized nut or induction hardened thread shaft with phosphate coating available

  • Shaft supports, actuator drives, and linear motion units available

  • Greasing keeps dust raised to a minimum

Self-locking leadscrews

Non-ball leadscrews for vertical applications self-lock and prevent backdriving, without an external brake.

Features & benefits

  • Diameters from ⅛ to 15/16 in. with leads from 0.02 to 3 in.

  • Sliding friction between nut and screw converts rotary input motion into linear output motion

  • 303 stainless steel; easily machined without being hardened

  • Accuracy comparable to ground ballscrews
