Frequently Asked Questions (FAQ)
-
What is the difference between NU206 and NJ206 bearings?
NU206 has a double-ribbed outer ring and a single-ribbed inner ring, allowing axial displacement of the shaft. NJ206 has ribs on both sides of the outer ring, providing axial location in one direction. Choose based on your application’s axial movement requirements. -
Can this bearing be used at high temperatures?
Standard NU206 bearings are designed for operating temperatures up to about 120°C. For higher temperatures, special heat-stabilized steel or alternative lubricants are recommended. Contact us for custom solutions. -
Is the C0 clearance suitable for all applications?
C0 (normal) clearance is suitable for most standard applications with moderate temperature differentials. For applications with high thermal expansion or interference fits, you may need C3 or C4 clearance. We can supply other clearances upon request. -
Do you provide bearings with seals or shields?
Yes, the open design can be upgraded with rubber seals (2RS) or metal shields (ZZ) to protect against contamination. Please specify when ordering. -
What is the typical lead time for bulk orders?
Lead time varies by quantity and customization. For standard NU206 bearings, we typically ship within 7–15 days after order confirmation. For large volumes, please inquire. -
How do you ensure the quality of your bearings?
We follow strict quality control processes: incoming material inspection, in-process monitoring, dimensional measurement, and final noise/vibration testing. Our factory is ISO9001 certified, ensuring consistent quality. -
Can I get a sample before placing a bulk order?
Yes, we offer samples for evaluation. Sample cost and shipping are negotiable. Please contact our sales team to arrange. -
What is the warranty period for this bearing?
We provide a warranty against manufacturing defects for a period of 12 months from the date of shipment. The warranty covers replacement or repair, excluding misuse or improper installation.
