What Is a Cross Roller Slewing Bearing? A Cross Roller Slewing Bearing is a type of slewing ring that uses cylindrical rollers arranged in alternating 90-degree directions (crossed), allowing it to simultaneously support radial, axial, and moment loads with high precision and rigidity. It is specifically designed for applications where high positioning accuracy, smooth rotation, and […]
What is a WE Series Slew Drive? The WE Series Slew Drive is an upgraded, fully enclosed slewing transmission system designed for superior environmental resilience. Unlike the SE series which balances compactness and performance, the WE (Weather Enclosed) series is engineered specifically for outdoor and harsh-condition applications—making it a favorite for renewable energy systems, construction […]
What Is a VE Series Slew Drive? The VE Series Slew Drive—short for “Vertical Enclosed”—is a fully enclosed worm gear slewing unit engineered specifically for vertical axis mounting. With a compact profile, high torque density, and weather-resistant casing, the VE series is ideal for solar trackers, vertical booms, robotic arms, and directional antennas that require […]
What is a VE Series Slew Drive? The VE Series Slew Drive is a specialized rotary drive solution designed for vertical installation. Featuring a fully enclosed housing and integrated worm gear system, the VE (Vertical Enclosed) series is optimized for applications where the drive axis must remain upright, such as tower-top trackers, vertical axis wind […]
What Is a Three-Row Roller Slewing Bearing? A three-row roller slewing bearing is a high-load capacity bearing that consists of three separate raceways, each with its own roller set—one for axial loads, one for radial loads, and one for tilting moments. This design allows the loads to be distributed across three rows of rollers, significantly […]
What is a Three-Row Roller Slewing Bearing? A Three-Row Roller Slewing Bearing is a high-capacity rotational bearing system that features three separate rows of rollers—each row designed to carry different types of load. Unlike single or double-row ball bearings, this design separates axial, radial, and tilting moment loads across three distinct paths, dramatically increasing the […]
What Are Spur Gear and Worm Gear Drives? Spur gear drives and worm gear drives are two of the most widely used mechanical power transmission systems. Both are used in slew drives to enable controlled rotational movement between components. However, their structure, performance characteristics, and application suitability differ significantly. A spur gear drive uses parallel shafts and straight […]
What Is a Slewing Drive? A slewing drive is a complete, compact rotary actuator system that integrates a slewing bearing with a driving mechanism—commonly a worm gear or spur gear—along with housing, seals, and input options for electric, hydraulic, or planetary motors. Slewing drives enable rotational movement and load support with high torque transmission and […]
Introduction: The Role of Slewing Bearings in Wind Energy Systems Wind turbines are complex electromechanical systems designed to convert kinetic energy from wind into electrical power. At the heart of this process lies a set of crucial components responsible for enabling smooth rotation, efficient tracking, and structural alignment—one of the most important being the slewing […]
What is a Slewing Bearing in Solar Tracking Systems? A slewing bearing in solar trackers is a large-diameter rotational bearing that enables the controlled movement of photovoltaic (PV) or concentrated solar power (CSP) panels. Installed at the core of single or dual-axis solar tracking systems, slewing bearings allow solar modules to follow the sun’s path […]
