634ZZ is a miniature ball bearing measuring 4 × 16 × 5 mm: 4 mm bore, 16 mm outside diameter and 5 mm width. ZZ means metal shields on both sides, which keep the grease in and larger particles out.
Other 4 mm bore bearings in our special range: MR84ZZ, 604ZZ, 684.
We supply the 634ZZ in multiple brands, from a single piece for a repair to bulk quantities, and can source more at short notice.
Why 634ZZ 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 634ZZ price on WhatsApp.
