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;





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

Slewing Ring Bearings------Applications:
Slewing ring bearings are widely used in industry and known as "the machine joints"
Hereunder is the specific slewing bearing applications
1. Construction machinery (e.g. cranes, excavators, loader, scraper)
2. Metallurgical machinery (e.g. for steel plant)
3. Heavy machinery equipments (e.g. mining machinery, concrete machinery)
4. Marine machinery equipment (e.g. vessel, port hoisting machine, port oil transfer equipment, onshore and offshore crane)
5. Light machinery equipments (e.g. paper machine, plastic, rubber machine, weave machine)
6. Wind power generator
7. Packing machinery


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 Bearings------Packaging Details:
Step 1: Covered with the anti-rust oil
Step 2: wrapped with the plastic film;
Step 3: Packed with Kraft paper and professional belts;
Step 4: Put into wooden box to avoid the rust or the moist;
Remark: Normally, plastic film+ Kraft +belt+ wooden box, but customized packing available,
