Linear Positioning Actuators

MiniTec has launched a new range of linear positioning actuators based on and completely compatible with its ProfileSystem range of machine framing and building components. The precision ballscrew driven 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. The lateral slots also provide a fixing point for datum sensors and limit switches and the modular design includes a stainless steel barrier strip and cover arrangement that 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 actuator will suit large area gantry, pick & place and robotic handling systems. The product is delivered as standard with lubricated-for-life dual linear rail ball 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.
