FAQ

Frequently Asked Questions

What is C3 clearance in a bearing?
C3 clearance is a greater-than-normal radial clearance between the balls and raceway. It is used when the bearing will operate at elevated temperatures (which cause thermal expansion, tightening the fit), when the bearing is press-fitted onto the shaft (which reduces clearance), or in applications where vibration tolerance is needed. Standard clearance is CN; C3 is next larger.

Yes. Gulf Union Ozone stocks Koyo 6003 ZZC3 (666-6003 ZZC3) and related Koyo bearings in Jeddah. WhatsApp +966 55 098 8062.
Can I use 6003 ZZC3 instead of 6003 ZZ?
Yes, in most cases. 6003 ZZC3 is a direct replacement for 6003 ZZ where C3 clearance is acceptable. If the original bearing is CN (normal clearance) and the application has no temperature elevation or interference fits, either will work. When in doubt, use C3 for motors and hot applications.
