What Is a Double Row Ball Slewing Bearing? A double row ball slewing bearing is a large-diameter rotational bearing that contains two rows of steel balls arranged in staggered or parallel configurations. These bearings are designed to simultaneously support axial, radial, and moment loads with enhanced stability and durability, making them ideal for large industrial […]
What is a Customized Spur Gear Drive? A Customized Spur Gear Drive refers to a rotary actuator engineered to meet unique project requirements beyond standard specifications. Unlike generic gear units, these drives are tailored in terms of gear ratio, housing dimensions, material composition, motor interface, and control system integration to match the specific mechanical, environmental, […]
What Are Customized Slewing Drives? A customized slewing drive is a specially engineered rotational actuator that has been adapted from a standard model to meet specific requirements in terms of size, gear configuration, mounting interface, sealing, load capacity, or environmental resistance. While standard slew drives from manufacturers like LDB cover a wide range of applications—from solar […]
What is Slew Drive Customization? Slew Drive Customization refers to the process of designing and engineering a slewing drive unit specifically tailored to meet unique mechanical, environmental, or performance requirements. Rather than relying solely on off-the-shelf solutions, customization enables manufacturers and engineers to optimize torque capacity, gear ratios, mounting interfaces, sealing levels, and motor compatibility […]
What Is a Cross Roller Slewing Bearing? A cross roller slewing bearing is a type of precision rotational bearing that features cylindrical rollers arranged alternately in perpendicular (90-degree) orientations between two raceways. This crossed arrangement allows the bearing to simultaneously handle axial, radial, and moment loads while maintaining high rigidity and minimal rotational clearance. Because […]
What is a Cross Roller Slewing Bearing? A Cross Roller Slewing Bearing is a type of rotational bearing where cylindrical rollers are alternately arranged at 90° to each other between inner and outer rings. Unlike traditional ball bearings, the cross-roller configuration enables ultra-high stiffness, smooth motion, and precise load management in both axial and radial directions—plus […]
Introduction: The Importance of Choosing the Right Gear Type In mechanical engineering and industrial automation, gear selection is foundational to ensuring performance, efficiency, and reliability. Among the most common types of gears used in gear drives and motion systems are spur gears and helical gears. While both serve the purpose of transmitting torque and motion, […]
What Are Single and Double Row Ball Slewing Bearings? A slewing bearing is a specialized mechanical component designed to support heavy radial, axial, and moment loads while allowing smooth rotational movement. Slewing bearings are essential in construction equipment, renewable energy systems, and industrial automation. Among the most common types are: Single row four-point contact ball bearings, […]
What is a Double Row Different Diameter Ball Slewing Bearing? A Double Row Different Diameter Ball Slewing Bearing is a unique structural design within the slewing ring family. It features two rows of balls of unequal diameter positioned at different radii. This special configuration allows for enhanced load distribution, combining the load advantages of different ball […]
What is a Slewing Bearing? A slewing bearing is a large-diameter rotational bearing that can support axial, radial, and moment loads simultaneously. It enables rotation between two structural elements, often without needing a central shaft. Slewing bearings are integral components in construction machinery, wind turbines, industrial robots, medical imaging equipment, and solar tracking systems. Traditionally, […]
