What is an SE Series Slew Drive? The SE Series Slew Drive is a fully enclosed rotary drive system that integrates a worm gear, slewing bearing, and housing into a compact, self-contained unit. Built for durability and precision, the SE (Standard Enclosed) series delivers smooth, controlled rotational movement in applications requiring tight space utilization, environmental protection, […]
What is an SDE-PDE Series Slew Drive? The SDE-PDE Series Slew Drive is a dual-axis rotary actuator system combining two independently driven worm gears and slewing bearings. Designed to allow motion along both the azimuth and elevation axes, these drives are primarily used in dual-axis solar tracking systems, satellite antennas, and precision machinery requiring synchronized […]
What is an S Series Slew Drive? The S Series Slew Drive is a simplified, single-worm rotary actuator that offers essential performance at an optimized cost. Compact, reliable, and easy to install, the S Series is ideal for applications that require moderate load support, smooth rotation, and long service life without excessive customization or complexity. Unlike […]
What is a Four Point Contact Ball Slewing Bearing? A Four Point Contact Ball Slewing Bearing is a type of rotational rolling-element bearing that allows one row of balls to contact the raceway at four points. This unique geometry enables the bearing to carry axial loads in both directions, radial loads, and tilting moments—simultaneously. Because of […]
Introduction: What Are Spur Gear Drives and Their Role in Automation? In the rapidly evolving world of industrial automation, precision, repeatability, and reliability are paramount. At the heart of many motion control systems is a simple yet powerful component: the spur gear drive. A spur gear drive transmits mechanical power through straight-toothed gears that are mounted […]
Introduction: What Is a Slew Drive and Why Is It Essential in Solar Tracking? A slew drive is a compact, self-contained gearbox that controls rotational movement in machinery by integrating a worm gear or spur gear with a slewing ring bearing. In solar tracking systems, especially in photovoltaic (PV) and concentrated solar power (CSP) installations, slew […]
Introduction: What Is Slewing Bearing Material Selection and Why Does It Matter? Slewing bearings are crucial mechanical components designed to handle axial, radial, and moment loads in a variety of heavy-duty applications. These bearings are used in cranes, excavators, solar tracking systems, wind turbines, and many other rotating or load-bearing platforms. One of the most overlooked […]
Introduction: Why Is Lubrication Critical for Slewing Bearings? Slewing bearings are essential components in heavy-duty machinery such as cranes, excavators, wind turbines, and industrial robots. Designed to handle axial, radial, and moment loads simultaneously, these bearings experience substantial stress and wear during operation. Proper lubrication is not just a maintenance task—it is a critical factor […]
Introduction: Why Slew Drive Integration Matters in Automation In today’s era of intelligent manufacturing and autonomous systems, motion control precision and system responsiveness are no longer optional—they are fundamental. Slew drives, which combine a slewing bearing and gear mechanism in one compact unit, are essential for applications requiring controlled rotation and load-bearing performance. When integrated […]
What Are HSE and S Series Slew Drives? Slew drives are vital components in automation systems that require controlled rotation under load. Among the diverse product lines offered by LDB, two standout series—the HSE Series and the S Series—serve different automation needs. The HSE Series Slew Drive is a high-torque, dual-axis capable solution designed for demanding applications […]
