Product Q&A
Q:How to distinguish genuine NSK bearings from counterfeits?
A:
Check for sharp, clear laser-etched markings on the bearing rings. The packaging should be high-quality with clear printing. Purchase only from authorized NSK distributors and request certification if needed.
Q:What is the meaning of the suffix 'DDU' in NSK bearings?
A:
'DDU' indicates Non-Contact Rubber Seals on both sides. This design offers excellent dust protection with very low friction and torque, suitable for high-speed applications.
Q:What is the difference between C0 and C3 clearance? When should I use C3?
A:
C0 is standard clearance. C3 is larger than C0. It is typically used in applications where the inner ring heats up significantly more than the outer ring (e.g., electric motors), preventing preload due to differential thermal expansion.
Q:Can NSK sealed bearings be re-lubricated?
A:
Generally, bearings with contact seals (e.g., DD, DDU) are not designed for re-lubrication as the seal can be damaged. Bearings with shields (ZZ) or non-contact seals (VV) sometimes allow for re-lubrication, but it's best to consult NSK technical documentation for the specific bearing type. Open bearings are designed for re-lubrication.
Q:What are the main applications for these bearings?
A:
Applications include high-speed machine tool spindles, automotive electrification, heavy-duty industrial gearboxes, home appliance motors, and robotics and automation.
