A new addition to Parker Electromechanical’s ET ElectroThrust range of linear actuators claims to offer enhanced performance and an extended working life. The new ETV100 is derived from the ET100 electric cylinder and utilises the same basic design in combination with higher performance key components.
The performance of the new ETV actuator is accomplished through the use of a C7 ballscrew, with a 6-circuit nut instead of a 3-circuit one. Further changes include the integration of taper roller bearings and the addition of a bearing lubrication point.
While the upgraded ballscrew provides the benefit of double the static and dynamic capacity, the taper roller bearings provide an increase of load capacity of three times when compared to the original angular contact bearings.
The ETV100 offers thrusts in excess of 21kN, stroke lengths of up 1500mm and ±0.07mm repeatability. With a ballscrew diameter of 40mm, two pitch options of 5mm and 10mm are offered, permitting linear speeds of up to 340mm/second.
The ETV100 is available in both direct and belt-driven parallel drive configurations and features the same standard options (as other actuators in the ElectroThrust range) for rod-end configuration and cylinder mounting. An IP65 rated version is also available, suitable for use in wash down, external and contaminated environments.
Together these enhancements both expand the scope of applications open to the ElectroThrust range as well as extending the actuator’s working life in applications previously satisfied by the existing ET100 actuators.
Typical applications include materials handling and feed duties, testing equipment, pick-and-place tasks, as well as valve/flap actuation. With the IP65 option the ETV100 is also ideally suited for use in food and beverage applications where system wash down is a prerequisite.
