The three row roller slewing bearing has three seat rings,which separate the upper,lower and radial raceways,it made each row of the roller’s load capacity can be specified and can bear different loads simultaneously.
Slewing ring bearings have unique load-bearing characteristics and are usually used in hoisting machinery, excavators, slewing tables, wind power generators, telescopes and tank turrets. Through the improvement of processing methods and the renewal of design concepts, slewing bearings can be applied to occasions with smaller dimensions, more complex structures and more precision.
If pits are required without pit inclinations, as is the case for fence posts, fountains or heat pumps, drilling equipment can be used. For this, great depths must be conquered, which will result in high speeds and long intervals of operation on the slewing ring. Their malfunctioning would delay the work, and perhaps even lead to the tool being damaged. LONGWEI can draw on its experience from various different areas of application here and develop robust and long-lasting solutions.
