FAQs
What are the main applications of NTN 6308 ZZCM/5K bearings?
The NTN 6308 ZZCM/5K is widely used in automotive hubs, conveyor systems, pumps, and industrial machinery due to its high load capacity and reliability.
How does the ZZ seal benefit this bearing?
The ZZ metal shields protect against contaminants while retaining lubrication, enhancing the bearing’s lifespan and reducing maintenance costs.
Can NTN 6308 ZZCM/5K handle axial loads?
Yes, it supports moderate axial loads in both directions, though its primary strength lies in handling radial loads efficiently.
Is this bearing suitable for high-speed applications?
Absolutely. The NTN 6308 ZZCM/5K is engineered for high-speed performance with minimal friction and heat generation.
Does the bearing require lubrication?
The double metal shields (ZZ) offer protection against contaminants, but pre-lubrication is recommended for extended performance in demanding applications.
