Product Description

LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball slewing ring bearings, roller slewing bearings and precision slewing ring bearings as per customer's different technical requirements.

Slewing ring bearing is also called slewing ring, slewing bearing, turntable bearing, and rotary bearing.
Slewing ring bearing is a bearing that able to bear axial load, radial load and overturning torque. Under normal circumstances, slewing ring bearings have their own mounting holes, lubricant holes and seal holes, to meet the different needs of the various host working under the various conditions;

Single row four point contact ball slewing bearings
This kind of slewing bearings can support high dynamic loads, transmitting axial and radial forces simultaneously as well as the resulting tilting moments. Applications of this kind of bearings are hoisting, mechanical handling and general mechanical engineering etc.

Single row cross roller slewing bearings
This kind of bearings can support combinations of large radial force, medium axial force and tilting moment with small or zero clearance. Main applications of this kind of bearings are hoisting and mechanical handling and general mechanical engineering etc.




Double row different ball diameter slewing bearings
This kind of bearings can support high static loads with simple structures. They are mainly used in situations with variation load position and direction and continuously rotating. Main applications of this kind of bearings are deck hoisting, mining and material handling etc.

Triple row cylindrical roller slewing bearings
This kind of bearings has high load carrying capacity. Under same loads, this kind of bearings has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc.


On the other hand, slewing ring bearing itself has characteristics of compact structure, guide rotating convenient, easy to install and maintaining easily.


Roller/ball combination slewing bearings
This kind of bearings can support high axial load and low tilting moments. Usually they are large diameter slewing bearings. Applications of this kind of bearings are mining and materials handling etc.

Slewing Ring- Seal 
The sealing of slewing bearing is mainly to prevent the filled grease from leaking out, and also to prevent external dust, impurities and moisture from entering the inside of the bearing and affecting the normal operation of the bearing.

Since most of the slewing bearings work under heavy loads and low speeds, the sealing form of the bearings adopts two structures: rubber seal ring seal and labyrinth seal. The rubber sealing ring itself has a simple structure, small space occupation and reliable sealing performance. The disadvantage is that it is prone to early aging under high temperature conditions and loss of airtightness. Therefore, under high temperature conditions, the slewing bearing should adopt a labyrinth seal. In addition, the material of the sealing ring under high temperature is high temperature resistant fluoro rubber.




Slewing ring bearing- Maintain
1. The slewing bearing should be greased regularly. According to different types of slewing bearings, the specific grease filling time is as follows: the ball type is filled with grease every 100 hours of operation; the roller type is filled with grease every 50 hours of operation .

2. The sundries on the surface of the slewing ring should be removed frequently during use, and the sealing strip of the slewing ring should be checked for aging, cracking, damage or separation. If one of these conditions occurs, the sealing strip should be replaced in time to prevent debris from entering the raceway and the loss of grease.

Pay close attention to the operation of the slewing ring during use. If you find that the noise, impact, or power suddenly increases, you should stop the machine immediately for inspection until all the faults are eliminated, and disassemble and inspect if necessary.
