SKF releases next-generation electromechanical linear actuators

Powerful new actuator series widens scope for hydraulics replacement in agricultural and construction equipment.

Making its debut at CONEXPO-CON/AGG 2017, an efficient and powerful new range of electromechanical linear actuators from SKF is set to provide viable replacements for many more hydraulics applications in construction vehicles and agricultural machinery.

SKF has substantially increased the thrust and holding force of its CAHB electro-mechanical linear actuators, as well as achieving a marked improvement in the sealing of these units, from IP66S to IP69K/66M (with Gore automotive vent). Three new products – CAHB-20E, CAHB-21E and CAHB-22E – offer more than double the rated load compared with previous CAHB designs, to deliver a maximum thrust of 10,000N and a holding force of up to 20,000N, ensuring maximum operational safety.

This vastly improved performance means that the new CAHB-E series is now a viable
drop-in replacement for many more hydraulically actuated systems in agricultural and construction equipment, reducing the complexity of existing hydraulic circuits, improving operational efficiency and reliability, simplifying installation and ongoing maintenance, and introducing new levels of speed and precision.

The new series offers additional benefits, including an optional manual override with integrated hand crank that enables the units to be adjusted without power or need for special tools, plus optional absolute or incremental position feedback. The new actuators are also more compact, maintaining stroke length while featuring a shorter retracted length.

The CAHB-2XE series is the latest addition to SKF’s BeyondZero customer solutions, which are designed to bring significant environmental benefits to customers. The CAHB-2XE series saves as much as 20 % of the energy required by alternative hydraulically actuated systems. It requires no consumables such as hydraulic oil and seals and is therefore a much cleaner, leak-free, more cost-effective and environmentally friendly solution for OEMs and machine builders.

SKF is a leading global supplier of bearings, seals, mechatronics, lubrication systems, and services which include technical support, maintenance and reliability services, engineering consulting and training. SKF is represented in more than 130 countries and has around 17,000 distributor locations worldwide. Annual sales in 2015 were SEK 75 997 million and the number of employees was 46 635. www.skf.com
