LYJW's professional team has capabilities of fulfilling your requirements by providing customized slewing bearings. All technicians in LYJW are engineers with professional expertise. Production operators have rich experience in bearing manufacturing. Quality controllers have more than 5 years of experience in bearing quality inspection.
LYJW bearing rings are made of high quality 42CrMo/50Mn and the raceway surface is quenched. We can provide rings of other materials according to customer’s specific requirements.
2.Rustproof surface coating
Coating on the bearing surface can lubricate and protect the bearing. We provide yellow chromate surface coating film which can prevent rust for 5 to 10 years. Other rustproof surface coatings are also available upon request.
Quenched GCr15 or GCrl5SiMn steel rollers feature high abrasion resistance and long service life.
There are different types of bearing cages used for slewing bearings, such as integral cage, segmented cage or spaced cage. The integral cage or segmented cage is made of no. 20 steel or ZLl 02 cast aluminum alloy. The spaced cage is made of polyamide 1010 resin, ZLl 02 cast aluminum alloy, QALL0-3-1.5 aluminum bronze or GRPA66-25 nylon. Different cages can also be selected according to the specific application conditions provided by users.
5.Lubricating Grease:a proper lubricating grease is selected based on the load, temperature, vibration, and environmental conditions of bearing and below characteristics are necessary:
- Good waterproofness and resistance against high or low working temperature
- Upper limit of the normal working temperature is at least 20℃ higher than that of the slewing bearing.
- Excellent resistance against abrasion and extrusion.
- Appropriate consistency (for centralized lubricating system).
The lubricating grease commonly used in slewing bearings includes calcium-based grease, lithium-based grease, aluminum-based grease, etc., which can be chosen according to specific needs.
