The latest HPLA Linear Actuator from Parker Electromechanical is designed to provide precision positioning of heavy loads at high speed. The new actuator, which has a thrust force of 5,500N, will carry loads of up to 1.6 tonnes at speeds up to 5m/s and position them to a repeatability of +/- 0.05mm. It is available in either timing belt or rack and pinion configurations. Standard travel options for the timing belt drive module are up to 20m and 50m for the rack and pinion drive.
Extending the range of applications for Parker Electromechanical’s HPLA further is the facility to install the units in any orientation and the possibility to configure the rack and pinion version to any length by splicing units together.
With both design options, the load-carrying carriage can be supplied with either synthetic load bearing wheels running in a high precision anodised aluminium profile, or hardened steel wheels running on steel guideways. The first option is ideal for cleanroom or test/inspection applications, whilst the second provides higher load bearing capacities for heavy-duty applications, such as required for materials handling and palletising.
Also, for food related applications, the actuator can be supplied with a steel cover for the drive belt, to avoid the risk of particulate contamination, and a corrosion resistant coating suitable for washdown environments.
The inherent strength and rigidity of the lightweight aluminium profile has been made possible through the use of FEA (Finite Element Analysis – load/structure analysis), and results in a compact unit with high energy efficiency.
The modular construction of the HPLA linear actuators makes them easy to specify, install and use, either for single or multi-axis configurations.
Parker Electromechanical can supply the HPLA linear actuators without a drive module, for use as free-running guide units, and are available with a range of options, including fitting or connecting plates, position sensors, limit switches, integrated linear encoders and cable carriers.
