Introduction
The XSU14 series comprises three types of bearing: the crossed roller slewing bearing, the cross roller turntable bearing and the four-point contact ball turntable bearing. All three bearings are supplied without a gear ring. Installation with a seal, an oil cup and a small range of adjustable clearance torque is also available. The accuracy of these bearings is suitable for a variety of working conditions.
The turntable bearing is capable of bearing large radial loads, axial loads, overturning moments and other comprehensive loads simultaneously. It combines multiple functions, including support, rotation, transmission and fixation. Its 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 industries.
Features of Turntable Bearings
1. Crisscrossed Rollers: The rollers are oriented at a 90-degree angle to each other, alternately crossing each other in a single raceway. This unique arrangement enables them to withstand complex loads from multiple directions.
2. High Rigidity and Precision: Crossed roller slewing bearings have minimal internal clearance, resulting in high rigidity and low deformation under load, making them ideal for applications requiring precise motion.
3. Compact Design: These bearings provide high load capacity and precision in a relatively small, compact form, allowing them to fit into space-constrained applications.
4. Smooth Rotation: Due to the design and arrangement of the rollers, crossed roller bearings enable smooth, controlled rotation, making them ideal for applications where consistent movement is crucial.
How to Select a Turntable Bearing
1. Load Requirements: Determine the type (axial, radial, moment) and magnitude of the load.
2. Precision: Higher precision bearings may be required for robotics or medical equipment.
3. Environmental Factors: Consider dust, moisture, and temperature, as these can impact bearing performance.
4. Mounting Design: Some applications may benefit from flange-mounted designs for ease of installation.
