Enhanced precision and productivity with new SKF actuators for off-highway applications

The range has been specifically developed for off-highway vehicles, and fulfils a number of functions, including articulated dump trucks, tractors and backhoe loaders. The actuators have been engineered to withstand harsh environmental demands and have undergone an extensive series of mechanical, environmental and electronic trials. In particular, the units are proven to resist wide temperature swings, chemicals, dirt, dust, water, vibration and other demanding operating conditions. Improved robustness brings increased machine uptime and a reduced risk of failure.

The virtually maintenance-free designs minimise downtime and cost, while the hydraulic-free actuation eliminates the risk of hydraulic fluid leaks which can result in impaired function, with the potential risk of fire. Capable of operating at temperatures from -40 to +85°C at a 25% duty cycle, the new electromechanical actuators feature robust metal gears and corrosion resistant housings. Furthermore, the extensive testing of the units considerably reduces validation time and costs, as well as warranty issues.

The new actuators have been applied to lifting and movement functions such as engine hood lifting and ergonomic functions like foot step deployment and door opening/closing control in large vehicles. They have also been used for levelling and height adjustment functions for better workplace convenience and operator comfort.

“With the introduction of our new actuators, we are able to offer OEMs the flexibility they need to design the next generation of more productive, cost effective, eco-friendly off-highway equipment,” said Phil Burge, Communication Manager at SKF. “Additionally, we can provide a range of engineering consultancy services backed by decades of experience with demanding actuator applications in various industries, to help OEMs create custom solutions.”

The actuators are available in two series, CAHB-20/21, for medium to heavy load applications, and CAHB-10, for low load applications, with both series IP-66 rated.
