Roller screw actuators save energy and maintenance

Olsen Engineering UK product story

Olsen Engineering's Tritex units package up the actuator, the servomotor, encoder, amplifier and positioner in one compact, efficient frame, dispensing with the need to mix and match vital components.
Drives can make a valuable contribution to energy saving and carbon reduction in linear motion as well as rotary motion devices.
Hydraulic actuators are, at best, around 50% efficient and a pneumatic system without costly air leaks is a rarity.
Servo electric linear actuators, however, are typically 90% efficient and offer significant advantages besides their energy saving capabilities.
Roller screw servo actuators offer greatly increased life in comparison to ball screw devices in addition to offering faster response, greater accuracy, higher loads and less backlash.
For this reason roller screw units are rapidly becoming the industry standard when robust linear motion is called for.
Olsen Engineering's Tritex units package up the actuator, the servomotor, encoder, amplifier and positioner in one compact, efficient frame, dispensing with the need to mix and match vital components and then cable them together, a process that is frequently a source of reliability problems.
