Frequently Asked Questions
Q1What are deep groove ball bearings used for?
Deep groove ball bearings are the most widely used bearing type, suitable for electric motors, pumps, household appliances, power tools, automotive alternators, conveyor idlers, and fans. They handle moderate radial and axial loads in both directions at high rotational speeds up to 17,000 RPM.
Q2What is the speed limit of deep groove ball bearings?
ANDE deep groove ball bearings reach limiting speeds up to 17,000 RPM depending on bore size, lubrication, and seal configuration. Open bearings achieve the highest speeds; shielded (ZZ) designs reduce the limit by approximately 10–15%, and contact seal (2RS) versions by 20–30%.
Q3Should I choose shielded (ZZ) or sealed (2RS) deep groove ball bearings?
Shielded (ZZ) bearings use non-contact metal shields that allow higher speeds but offer moderate contamination protection. Sealed (2RS) bearings have rubber contact seals providing superior dust and moisture exclusion but slightly lower speed limits and higher friction. Choose ZZ for clean high-speed environments, 2RS for dusty or wet conditions.
Q4What is the difference between C3 and normal clearance?
C3 clearance is greater than normal (CN) clearance. Use C3 when thermal expansion is expected (motors, high-temperature applications), when interference fit is used on the shaft, or when the bearing operates with a temperature differential between inner and outer rings. Normal clearance is suitable for most standard applications at ambient temperature.
Q5Can deep groove ball bearings handle axial loads?
Yes. Deep groove ball bearings can support axial loads up to approximately 50% of the unused radial load capacity, in both directions simultaneously. For applications with dominant axial loads exceeding this, consider angular contact or thrust ball bearings instead.
