Working Principle: Rotary bearing is a kind of super-large bearing which can bear comprehensive load. It is also called "turntable bearing" because its shape resembles a plate. It can bear large axial load, radial load and overturning moment at the same time, and can replace the function of several common bearing combinations. Generally, it is suitable for mechanical equipment which bears huge overturning moment and makes relative rotation motion. It is a kind of composite bearing with high efficiency and high load-carrying capacity.
Rotary bearings generally have a diameter of 0.4-10 meters, with installation holes, internal or external gears, lubricating oil holes and sealing devices. They have the characteristics of compact structure, accurate and smooth transmission, flexible rotation, long service life, simple installation and convenient maintenance in daily use. For different requirements, there are many Rotary bearings. It can be widely used in lifting machinery, construction machinery, metallurgical machinery, medical machinery, transportation machinery, food machinery, textile machinery, material processing machinery, military equipment, aerospace equipment, power generation equipment, etc. In the field, it is an indispensable part of mechanical rotary device.
