What is the difference between slew plate bearings and turntable bearings?
The slewing bearing is a rotating bearing, mainly composed of steel balls and rolling elements. If you need a shaft or bushing that can rotate, a slew bearing is the ideal choice. So, what is the difference between slew plate bearings and turntable bearings?
First of all, in terms of working principle, the turntable bearing drives the rotation of the inner ring by rotating the main shaft, while the turntable bearing drives the rotation of the inner ring through its own rotation. Structurally, slew bearings generally use needle rollers, spherical rollers, thrust balls and other rollers as main parts, while turntable bearings use tapered rollers, thrust balls, etc. as main parts. In terms of selection, slew bearings are mainly used in large diameter or high speed situations, while turntable bearings are mainly used in small diameter or low speed situations.
Secondly, both slew plate bearings and slew table bearings can withstand radial force and axial force, but there are differences between them. The slew table bearing cannot rotate at the same time when it is subjected to axial load; while the slew plate bearing can rotate without any external load or with a constant load (but cannot rotate without any axial load).
Finally, in use, the turntable bearing has good pressure resistance and heat resistance. Therefore, it is more suitable for high-speed rotating machinery. When installing and using, pay attention to maintaining a balanced load on the rotating shaft or sleeve. It is generally required to keep the vertical distance between the two rotating surfaces relative to the center line of the load-bearing area constant.
