Roller Screw Actuator

Rolaram Actuator with Parallel Mount Motor

Rolaram Actuator with Right Angle Mount Motor

Rolaram Actuator with In-Line Mount Motor

More Technical Details High performance actuation with the planetary roller screw version of the Rolaram electric linear actuator, that provides a high load capability in a small envelope. The Rolaram roller screw actuator delivers critical actuation to demanding systems in any industry sector for high speed, high duty cycle, high accuracy and long life in a durable and reliable construction. Standard dynamic load capabilities up to 400kN with standard linear speeds up to 7500 mm/min. Customised and bespoke solutions are available, including designs for higher loads and speeds.

Ball Screw Actuator

More Technical Details Precision actuation with the ball screw version of the Rolaram electric linear actuator. There are 4 standard Rolaram linear actuator models, available with ball screw drive, which are the B050, B075, B100 and B125. While the ball screw version does not have the same force density as the roller screw version, they provide precision linear actuation solutions for low to high duty applications in a wide range of industry sectors. Standard dynamic load capabilities up to 65kN with standard linear speeds up to 8500 mm/min. Customised and bespoke solutions are available, including designs for higher loads and speeds.

Useful Information

Typical Applications

The Rolaram Linear Actuators typical Applications include Scissor platforms, lifting platforms, robotics, continuous paint pumps, medical beds, coiling machines, tundish cars, continuous operation process lines. Used across many sectors from defence, nuclear, Aerospace, metal processing, medical, automotive, offshore and marine, communications and food processing.

Rolaram Advantages

Rolaram linear actuators not only match the load capacity of hydraulic cylinders and exceed the load capacity of of conventional electro- mechanical actuators but also provide:

Ease of installation, no pipework, powerpack and valves
Easy to synchronise more than one unit
Accurate and repeatable positioning using simplified system
Low power consumption and running costs
No oil leaks, contamination or fire risk
Low noise system
Higher dynamic and speed capacity and longer life

Standard Features

Roller Screw and Ball Screw linear actuator versions
Right angle or parallel drive configurations
10 standard linear speeds for each model
Choice of end fittings; Clevis, Screwed End, Top Plate
Trunnion mounting (with or without feet)
Rear Clevis

Guided RAM (Anti-Rotation Mechanism)

Special Designs

The Rolaram linear actuator concept has been successfully applied in many varied ‘special’ applications, requiring for example:

Very high linear speed, over 50 metres/minute
Very high dynamic load, over 1000kN
In-line drive configuration
Auxiliary Drive Units
Temperature extremes or hazardous environments such as subsea
