What is the difference between slewing bearings and turntable bearings?

The precision of slewing bearings is low, and they are all at the wire level. Several or dozens of wires are normal, and they are mainly made by turning. The slewing bearing is a large bearing with a special structure that can withstand large axial load, radial load and overturning moment and other comprehensive loads at the same time. It integrates multiple functions such as support, rotation, transmission and fixation, and it has its own There are equipment holes, lubricants and sealing equipment for large equipment such as lifting and transportation machinery, excavators, construction machinery, port machinery, and wind power generation.

Slewing bearings usually consist of four major components: inner ring, outer ring, rolling elements, and barrier blocks. Because the core component adopts slewing bearing, it can withstand axial force and radial force at the same time. There are many ways, but the structural composition is basically the same. Generally speaking, the slew plate bearing itself has equipment holes, lubricating oil and sealing equipment, which can meet the different needs of various types of hosts working under different working conditions; on the other hand, the slew plate bearing itself has the characteristics of compact structure, guiding rotation Features include convenience, simplicity of equipment and easy maintenance.

The turntable bearing is a bearing that can simultaneously bear axial load, radial load and overturning moment and other comprehensive loads. It is a precision bearing with a special structure that integrates support, rotation, transmission, fixation and other functions. The turntable bearings are basically made of fully quenched bearing steel GCr15SiMn, which has good material hardness, high wear resistance and high structural stability; the turntable bearings are made of surface-quenched steel, which only undergoes surface heat treatment, is impact-resistant, and has good material processing economy, and is relatively The language arrangement has poor stability. Turntable bearings have high precision, basically at the micron level, and are mainly made by grinding.

Relying on its own characteristics and strict processing technology, turntable bearings can also withstand comprehensive directional loads and have high rotation accuracy. The structures of turntable bearings are quite different. YRT turntable bearings are ultra-high-precision turntable bearings, consisting of two rows of axial rollers. It is a combination of bearings and 1-row radial roller bearings. This series of bearings is difficult to process and requires high precision. It is suitable for precision CNC machine tools, measuring instruments, military equipment, etc.
