Linear Actuators Of Tandem Design

INA Lineartechnik oHG, Germany, introduces a range of driven linear actuators which can be matched to a wide variety of requirements. A tandem actuator of this type consists of two linear ball bearing and guideway assemblies arranged in parallel in a profiled aluminium support rail. A table is mounted on top of the two guidance systems and is driven by means of three pretensioned toothed belts. The actuators can be supplied with linear ball bearing and guideway assemblies having two rows of balls (MDKUE), four rows of balls (MDKUVE) or six rows of balls (MDKUSE). Linear actuators MDKUE, MDKUVE and MDKUSE can be used to move heavy loads with high moment loading about all three axes at speeds up to 3 m/s and accelerations up to 14 m/s2 with high positional accuracy. Since the triple toothed belt allows very high operating forces, this series is highly suitable for vertical axis applications. If even high moment loads occur, it is possible to use an extended table or several tables on the same rail. The system is characterised by a large number of benefits: high dynamic load carrying capacity, especially suitable for vertical application; high moment load carrying capacity; high rigidity; self-supporting profiled rail; significantly lower cost than two individual actuators; reduced assembly costs due to compact design and the fact that additional support structures are not required; and no need to align two units to each other.
