Product description Te ALBERT SDA is a modular direct drive linear actuator system for use in a wide range of applications and industries. Te actuators can operate wit fast linear speeds and ig duty in ig load conditions. Te SDA can be used as a single drive linear actuator. Alternatively, as ig precision motion control wit syncronisation between axis is possible, te SDA is a perfect solution as part of a multiaxis system. Available in different sizes wit a fully modular construction and vast array of accessories, te SDA can be configured to acieve bespoke application requirements. Te SDA as a rigid construction wit a fully sealed ousing, equipped wit robust axial and radial bearings and lifetime lubrication. Te use of a pivoting bracket attaced to te ousing, coupled wit a range of different spindle ends ensures a pivoting motion is possible. As te SDA is an electromecanical linear solution tere is no possibility of oil or air leaks as associated wit ydraulic and pneumatic cylinders. Te basic SDA version comprises of a selflocking trapezoidal spindle and running nut. Te input saft can be connected to a suitable motor and coupling to complete te drive arrangement. Te SDA is also available as a fully enclosed linear actuator solution were te spindle is enclosed witin a cover tube and te running nut is attaced to a pus rod. Te cover tube also as a guide bus fitted to elp guidance of te pus rod. As te construction of te SDA is fully modular a range of motor mounting flanges, bell ousings and couplings are available to connect various motor designs. For faster linear speeds and iger duty capability ball screw versions are available across te entire SDA range. Accessories: Lifting limitation Rotation prevention Safety nut Pivot pins Pivot mounting Couplings Motor adaptors Flanges Flanged bearings Support bearings Various front attacments and more.
