New TA-Series electric linear actuators expand the comprehensive Power Jacks linear actuator portfolio for sub-10kN rated units.
New TA-Series electric linear actuators expand the comprehensive Power Jacks linear actuator portfolio for sub-10kN rated units.
There are two basic models in the TA series: 2.2 and 4.4kN capacity units with linear speeds up to 1370mm/min.
These models are available with AC or DC motors and stroke lengths up to 300mm as standard.
Control options include a clutch (internal to gearbox) for overload and jam protection, limit switches that are fully adjustable over the full stroke (located within the metal housing for protection) and potentiometer feedback.
Rather than relying on a belt drive in the gearbox the units use all metal gears to drive a self-locking machine screw in the actuator's ram.
This provides safety and reliability for linear actuation without the need for an electric brake to hold the load when parked.
Plus, in order to reduce overall life costs of the actuator to the customer all models are lubricated to be maintenance free for normal operation.
