Screw Driven Modular Actuators

Screw Driven Modular Actuators

Screw Driven Modular Actuators use the finest acme and ball screws manufactured in the world. They allow for direct in-line motor mount with or without an in-line or parrallel gear box.

ACME SCREWS

Nook Industries acme screws are made of high strength materials. The screw shaft is made of high alloy steel. Nook acme nut material has been selected for low friction, minimum wear, long life,and clean operations.

BALL SCREWS

Nook Industries PowerTrac™ ball screws offer an efficient means of converting rotary motion to linear motion. A ball screw is an improvement over an acme screw just as an anti-friction ball bearing is an improvement over a plain bushing. 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.

V Groove Guided   External Roller Bearing Guided   Internal Roller Bearing Guided   Internal Profile Rail Guided  

V Groove Guided

The carriage moves along the unit guided by V-slides that are adjustable to reduce lash. The linear opening of the unit is sealed with a stainless steel cover band to make the unit splash-proof and dust-tight.

External Roller Bearing Guided

The carriage moves along the unit guided by hardened steel guide rods on the outside of the actuator that are adjustable to reduce lash. The linear opening of the unit is sealed with a stainless steel cover band to make the unit splash-proof and dust-tight.

Internal Roller Bearing Guided

The carriage moves along the unit guided by hardened steel guide rods on the inside of the actuator that are adjustable to reduce lash. The linear opening of the unit is sealed with a stainless steel cover band to make the unit splash-proof and dust-tight.

Internal Profile Rail Guided

The carriage moves along the unit guided an single or dual internal profile rail on the outside of the actuator that are adjustable to reduce lash. The linear opening of the unit is sealed with a stainless steel cover band to make the unit splash-proof and dust-tight.
