MiniTec launches new range of Profile System compatible actuators

The modular Linearmodul LMS provides up to 1400 mm of travel and is housed in a 90 x 90 mm extruded aluminium profile with standard T-slots on 45 mm centres that utilise MiniTec's wide range of interfacing and interconnection components. Lateral slots provide a fixing point for datum sensors and limit switches, whilst a stainless steel barrier strip and cover arrangement seals and protects the internal moving parts of the actuator. Aimed at applications where accuracy, durability and minimum installation space are important selection criteria, the LMS will suit large-area gantry, pick & place and robotic handling systems - as part of a complete MiniTec machine frame system - or as separate components, complete with MiniTec supplied motors, drives and motion controls. The LMS is delivered as standard with lubricated-for-life dual linear rail ball type bearings with matched carriages that support loads in all directions for speeds of up to 1.6 metres per second with the 16 mm diameter x 16 mm pitch ballscrew option. Other ballscrew pitch options include 4, 5 and 10 mm variants, and a T7 accuracy grade option features a preloaded nut system for 0.04 mm axial play and repeatability to 52 microns per 300mm. An acme screw version is also available, with a further choice of a preloaded nut arrangement for increased precision. The flexibility built into the range also extends to the choice of bearing system. The standard bearing system may be replaced with dual heavy-duty recirculating linear rail guides with four carriages, rated at a 10,000 km service life. Alternatively, a novel low-friction plastic bushing version can be supplied for an extremely economical positioning solution. The LMS actuator can be fitted with a pulley housing for belt drives, with adapter plates for servo or stepper motors, or as a manual hand-wheel driven unit.
