Linear actuators boost solar power generation

SKF has launched a new SKF Solar Linear Actuator that increases accuracy and efficiency in tracking the sun and cuts the maintenance costs demanded by alternative solutions.  

Designed to meet the demanding requirements of the solar power industry, the SKF Solar Linear Actuator can be used with photovoltaics, concentrating photovoltaics or concentrating solar power systems.
The robust design of the new SKF Solar Linear Actuator contributes to an increased level of reliability and drive protection. Higher static to dynamic load ratios permit solar power generation during high wind conditions, achieving greater positioning accuracy and exhibiting limited backlash for consistent tracking.  

Designed for 20-year service life, the actuators are virtually maintenance-free, requiring no downtime for part changes or re-lubrication, thereby reducing maintenance costs.
“Our advanced electromechanical technology offers improvements over today’s maintenance-intensive solutions and delivers high performance, accuracy and efficiency in tracking the sun’s position throughout the day and during seasonal changes, over the life of the system,” says Mahdi Sebti, Global Business Development Manager, SKF Renewable Energy.

SKF Solar Linear Actuators integrate a screw with gearbox, motor, bearings, lubricant, seals, limit switches, hall sensors and a circuit board; all protected in an IP 65 sealed housing to simplify installation, eliminate contamination and withstand extreme environments.

The new actuator joins SKF’s expanding portfolio of solar industry-related offers, comprising bearings and units, lubrication systems, sealing solutions, mechatronics, and engineering consulting and aftermarket services.
