FAQ

Frequently Asked Questions

What does 6303ZZ bearing fit?
KOYO 6303ZZ fits electric motor front/rear bearings, alternator bearings, cooling fan bearings, small pump shafts, and various automotive auxiliary equipment bearings. The 17×47×14mm dimension is a widely used standard across many OEM applications.
Do you supply Koyo bearings in Saudi Arabia?
Yes. Gulf Union Ozone stocks Koyo bearings including 6303ZZ, 6203-2RCS, 6003-ZZC3, 6304-ZZC3, and 6205-2RCS at our Jeddah warehouse. WhatsApp +966 55 098 8062.
What is the difference between ZZ and 2RS bearing seals?
ZZ (double metal shield) bearings have steel shields that retain lubricant and exclude coarse contamination but are not fully sealed — fine dust can enter. 2RS (double rubber sealed) bearings have rubber contact seals for full dust and moisture exclusion. 2RS offers better contamination protection; ZZ runs with slightly lower friction. Choose 2RS for dusty Saudi environments.
