Slewing Ring Bearings for crane
 
1) We can manufacture slewing ring bearings below:
1. Four-point contact ball slewing ring bearings
2. Double-row different diameter ball slewing ring bearings
3. Crossed cylindrical roller slewing ring bearings
4. Triple-row cylindrical roller slewing ring bearings
5. Cross-tapered roller slewing ring bearings
Besides, the slewing ring bearings can be non-geared, internal gear and external gear.

2) Characteristics for slewing ring bearings:
1. Single-Row Four-Point Contact Ball Slewing Bearing
High dynamic load capacity
2. Double-Row Ball Slewing Bearing
Better dynamic load capacity than Single-Row Four-Point Contact Ball Slewing Bearing
3. Single-Row Crossed Roller Slewing Bearing
Load support:
High static load capacity
4. Cross-tapered roller bearings'
The pre-interference of the bearings can support a greater rigidity and rotary accuracy.
5. Three-Row Roller Slewing Bearing
Load support:
Improved support capacity for the compacter structure
High support capacity

3) Applications for slewing ring bearings:
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. Military products (e.g. aerospace machinery)
8. Packing machinery


4) 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: Customized packing accepted
