Rotary table bearings and slewing bearings are literally different from each other. They are rolling bearings for mechanism support and rotation. However, for the mechanical industry, there are essential differences between the two. The former refers to high-precision rotating equipment, and then It includes large bearings for general-grade rotation, and the relevant bearing selection or equipment maintenance must be clear, what kind of bearings your equipment needs.
The slewing bearing is a large-sized bearing that can withstand a large load such as large axial load, radial load and overturning moment, and combines various functions such as support, rotation, transmission and fixing, and has its own belt. There are mounting holes, lubricating oil and sealing devices for large-scale equipment such as lifting and transporting machinery, mining machines, construction machinery, port machinery, wind power generation, etc. The rotary table bearings can also withstand the comprehensive direction by virtue of their own characteristics and strict processing technology. Load, and has high rotation precision, the bearing structure of the turntable is quite different, mainly including cross cylindrical roller bearing, cross tapered roller bearing and YRT rotary table bearing, wherein the cross roller bearing is divided into thin wall type (without mounting hole) And with mounting holes, both can be used for precision rotation, to meet the assembly requirements of * small installation space, cross tapered roller bearings are also suitable for high-speed rotation conditions; YRT rotary table bearings are ultra-high precision (close to P2) rotary table bearings It is composed of two rows of axial rollers and one row of radial roller bearings. This series of bearings is difficult to process and requires high precision. Bonding precision CNC machine tools, measuring instruments, military equipment and the like; thus selected bearing turntable or slewing bearing loads to be considered, partial load, speed, temperature, and many other means required to meet the actual needs.
