604ZZ is a miniature ball bearing measuring 4 × 12 × 4 mm: 4 mm bore, 12 mm outside diameter and 4 mm width. ZZ means metal shields on both sides, which keep the grease in and larger particles out.
It is also available in the Z3V3 grade, a low-noise, low-vibration quality class used in Chinese and Indian specifications: the higher the Z and V numbers, the quieter and smoother the bearing runs. Other 4 mm bore bearings in our special range: MR84ZZ, 634ZZ, 684.
We supply the 604ZZ in multiple brands, from a single piece for a repair to bulk quantities, and can source more at short notice.
Why 604ZZ prices vary
- Genuine or copy: fakes sell far below the real price and fail early. We sell only genuine bearings.
- Version: sealed, shielded, C3, stainless and low-noise versions cost more than the open bearing.
- Quantity: bulk and repeat orders are priced lower.
So we quote today’s price for each brand rather than list one number. Ask for the 604ZZ price on WhatsApp.
