General Features: Rotating Ball Screw and Translating Tube Ball Screw Models

• Integral 56 frame, C-face mounting flange.
• Three-piece flexible coupling for easy motor assembly (included).
• Four threaded holes in base for standard hydraulic cylinder, clevis end accessory attachment.  Tapped 1/2-20 UNF-2B.
• Ball-bearing type heat-treated screw and mating nut with rolling contact reduces friction to a minimum providing capability for higher speed and longer life with less power requirement.

• Steel worm and bronze gear set for quiet operation.  Available in 5:1 and 20:1 ratios.
• Rugged, lightweight aluminum housing is corrosion-resistant.
• Standard grease fitting on housing for easy lubrication of worm gear.
• Stop-disc at end of lifting screw prevents inadvertent run-off of ball nut.

General Features: Translating Tube Ball Screw Models

• Outer aluminum tube is corrosion-resistant and protects translating tube, lifting screw and nut.
• Wiper scraper seal in end of outer tube keeps dirt out and lubricants in.
• Bronze guide brushing inside of outer tube reduces lateral movement of translating screw.
• Translating tube is zinc coated for weather-resistance.

• Single or quadruple lead ball-bearing type lifting  screw and nut for high efficiency and long wear.
• Vent in outer tube prevents pressure build-up in the actuator.
• Furnished with standard clevis end.  Threaded end is available; and on special order, depending on application, and type of threaded connection may be substituted.
