XSA Series Turntable Bearings
Introduction
The XSA series precision turntable bearing, cross roller turntable bearing and four-point contact ball slewing bearing, with outer gear, can be installed with a seal, equipped with an oil cup, adjusted to a small range of clearance torque and is highly accurate, meeting the requirements of various types of working conditions.
The turntable bearing is capable of bearing large radial loads, axial loads, overturning moments and other comprehensive loads simultaneously. It integrates multiple functions, including support, rotation, transmission and fixation. The compact structure, simple installation and convenient maintenance make it ideal for heavy and low-speed applications, such as lifting machinery, excavators, turntables, wind turbines, astronomical telescopes, tank turrets and other devices. It is a highly versatile bearing that is widely used in a variety of settings.
The XSA series comprises crossed roller slewing bearings with external gear teeth.
Features of Turntable Bearings
1. High Load-Bearing Capacity: The crossed roller configuration allows these bearings to manage significant loads, making them ideal for demanding applications.
2. Simplified Drive System: External gearing facilitates connection to external pinion gears, motors, or other drive systems, reducing the need for additional components.
3. Reduced System Weight and Size: Eliminates the need for separate gears, allowing for a more compact system design.
4. Precision and Stability: The crossed roller arrangement minimizes play, ensuring stable, vibration-free rotation under high loads.
How to Select a Turntable Bearing
1. Load Requirements: Assess the bearing’s ability to handle axial, radial, and moment loads for your specific application.
2. Gear Pitch and Module: Ensure compatibility with the driving pinion to optimize engagement and minimize wear.
3. Precision Requirements: Choose a model with appropriate precision based on the application’s accuracy needs.
4. Environment and Sealing: For outdoor or harsh environments, look for models with suitable seals to protect against contamination.
