Precision Double-Row Ball Slewing Bearings

As a professional manufacturer of precision bearings, LZJM can provide ultra-high-precision double-row ball slewing bearings.Slewing bearings typically consist of four main components: inner ring, outer ring, rolling elements, and spacer blocks. Due to the use of slewing rings as their core components, they can simultaneously carry axial and radial loads. They have various forms but share similar structural components. Size Range: 170 mm - 7000 mm bore

Features

High load carrying capacity: Slewing bearings are designed to withstand large axial loads, radial loads and tilting moments and other comprehensive loads. Their structure is sturdy and able to withstand heavy loads and complex mechanical environments.
Compact structure and easy installation: The compact structure design of slewing bearings not only reduces the need for installation space, but also simplifies the installation process. It is usually equipped with mounting holes and positioning structure, which is convenient to integrate with mechanical equipment.
Smooth rotation and high precision: Since slewing bearings use rolling element (such as steel balls or rollers) to realize movement, their rotation is very smooth, reducing friction and vibration. This helps to improve the running accuracy and stability of the mechanism.
Long life and low maintenance: Slewing bearings are usually made of high-quality materials and advanced manufacturing process, so they have high wear resistance and corrosion resistance. Meanwhile, its sealing device and lubrication system also effectively prolong the service life and reduce the maintenance cost.
Multi-directional carrying: Slewing bearings are not only able to withstand load in a single direction, but also able to withstand load in multiple directions at the same time, including axial, radial and tilting moments, etc. This multi-directional carrying capacity makes slewing bearings have excellent performance in complex working conditions.
Good self-aligning function: Slewing bearings have a certain self-aligning function, that is, when the bearing is tilted or deflected, it can automatically adjust the position of the rolling element in order to maintain a stable operating state. This feature helps to reduce the additional load and wear caused by mounting error or vibration during operation.
