Heavy Duty Electric Cylinders

Ruggedly Designed Electric Cylinders

Electric Cylinders are ruggedly designed and produced in standard models with thrust capacities from 500 lbs. To 40,000 lbs. They are supplied in a Single Reduction, Double Reduction, or an In-Line Configurations. Electric Cylinders are intended for use in industrial environments and feature ground and hard chrome plated actuator tubes with industrial enamel paint on exterior surfaces. Heavy duty electric cylinders can be supplied for outdoor applications.

  • Use individually or in multiple arrangements.
  • Built to specification.
  • For outdoor applications, contact Nook Engineering for recommended alterations.
  • Ground and hard chrome plated actuator tubes.
  • Exterior surfaces feature industrial enamel paint (Epoxy, polyurethane and marine grades available on request).

Ball Screw Driven

Nook Industries ball screws are made of high strength materials. The screw shaft is made of medium carbon induction hardenable alloy steel. Ball nuts are manufactured from high grade bearing steel. Both the ball screw and nuts are heat-treated to a surface hardness not less than 56 HRC with a case depth suitably chosen to carry the load.

Single Reduction Electric Cylinder

DD Electric Cylinder Ball Screw Driven

  • Alloy steel worm drives a high strength bronze worm gear (drive sleeve).
  • Worm shaft supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication (sealed radial ball bearings on the Series 5 and Series 10 units). 
  • Ductile iron housing proportioned to support the rated capacity of the unit.
  • Ruggedly designed and produced in standard models with thrust capacities from 500 lbs. to 40,000 lbs.

Double Reduction Electric Cylinder

RAD Electric Cylinder Ball Screw Driven

  • Incorporate the same benefits as DD Electric Cylinders.
  • Include a second reduction for reduced input torque and lower travel rate.

Inline Electric Cylinder

ILA Electric Cylinder Ball Screw Driven

  • Have many of the same benefits of DD and RAD Electric Cylinders, including a rugged design and capacities from 1,000 lb to 21,000 lb.
  • Incorporate a direct drive without an internal reduction. The screw drive is directly coupled with an external speed reducer, stepper motor, servo motor, or NEMA mounted motors.

Keyed Inline Electric Cylinder

ILAK Keyed Electric Cylinder Ball Screw Driven

  • Have many of the same benefits of ILA Electric Cylinders, including a rugged design and capacities from 1,000 lb to 21,000 lb. ILA Electric Cylinders incorporate a direct drive without an internal reduction.
  • The screw drive is directly coupled with an external speed reducer, stepper motor, servo motor, or NEMA mounted motors.

Acme Screw Driven

PowerAc™ Acme screws are made form 4140 Alloy steel with a black oxide finish with a 2C (Centralizing) thread form. Nook acme nut material has been selected for low friction, minimum wear, long life, and clean operations.
