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. Military products (e.g. aerospace machinery)
8. Packing machinery
 
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,
