Linear ActuatorsKelston have partnered with several Companies to develop and supply special purpose Electro-Mechanical Linear Actuators for a specific requirement.
Driven mainly by precision Ball Screws and occasionally Roller Screws, we have designed and built Actuators with a load capacity of up to 500kN, so far!
If you have a specific load, speed, Envelope, Environmental, Dynamic or Quality requirement and can’t find an off the shelf product, we would like to talk to you.Anthony Best Dynamics supplies advanced
testing systems to the global motor industry for both research and development
and for production quality control. The company’s Suspension Parameter
Measurement Machine (SPMM) measures the kinematic characteristics of a
vehicle’s suspension and steering system. It is driven entirely by
electromechanical actuators designed and manufactured by Kelston.
first SPMM was installed in 1996. Its design has been continually updated and
the latest version (SPPM 5000) can accommodate large vehicles with a maximum
wheel base of 4,450mm and a nominal load capacity to 5,000kg.
A set of six actuators perform linear movement on five different axes. Each actuator is driven independently by its own servo motor drive. The actuators are fitted with positional control switches, which along with the servo motor, integrate with the SPMM control panel.
Each bespoke actuator consists of a spiral bevel gearbox rotating a worm and wheel gearset which drives a high precision ball screw.
