VSU Series Turntable Bearings
Introduction
The VSU series four-point contact ball slewing bearing, without gear ring, turntable bearing is a high-performance product that can be installed with a seal, equipped with an oil cup, and adjusted to provide optimal torque clearance in a range that suits your needs. Its accuracy is designed to meet the requirements of various working conditions.
The VSU series four-point contact ball slewing bearing and turntable bearing, which does not include a gear ring, is capable of bearing significant radial and axial loads, overturning moments, and other comprehensive loads. It is a highly versatile component that can perform multiple functions, including support, rotation, transmission, and fixation. The compact structure, simple installation and convenient maintenance make this product 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 product that is widely used in a variety of industries.
Features of Turntable Bearings
1. High Load Capacity: Turntable bearings can support substantial radial, axial, and tilting moment loads.
2. Smooth Rotation: They are designed to allow smooth, continuous rotation even under heavy load.
3. Precision: Some bearings are designed with high precision for applications where accurate positioning is critical, like in machinery or robotics.
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.
