A new range of compact linear actuators has been launched which can be supplied as an integrated unit, complete with drive, motor and gearbox., enabling both OEMs and end users to reduce the time and costs associated with machine design, build and maintenance.
Parker Hannifin's 'LCB' linear actuators can be used as an effective low cost option to replace both traditional rodless- and servo pneumatic devices in a wide range of applications, including materials handling, labelling, wrapping and general automation.
The LCB utilises maintenance-free bearings and so is reliable and requires minimal servicing. A unique device is built into the central aluminium profile of the LCB, creating a very robust, lightweight unit with a stroke of up to 5.5m. A timing belt, reinforced with steel wires, further improves high speed operation, repeatability and operating life. Available in two frame sizes, the LCB040 and LCB060 offer thrust forces of up to 160N and 560N, and typical payloads of 3kg and 15kg respectively.
In each case, the relatively low moving mass of the carriage assembly permits high dynamic movement to be achieved at speeds of up to 8m/s, with acceleration up to 20m/s2 and repeatability of within +/- 0.2mm. The low mass also helps to reduce power consumption, while the absence of recirculating ball mechanisms results in very low operating noise levels.
The LCB units can be combined to provide dual or multi-axis systems.
