MR128 is a miniature ball bearing measuring 8 × 12 × 3.5 mm: 8 mm bore, 12 mm outside diameter and 3.5 mm width. The open version is 2.5 mm wide. We supply it open, or with rubber seals on both sides (2RS) for protection against dust and moisture.

In MR numbers the digits give the outside diameter first and then the bore: MR128 is 12 mm across with a 8 mm bore. Other 8 mm bore bearings in our special range: SSF608ZZ, 8×22×11 2RS, 8×22×6 2RS.

We supply the MR128 in multiple brands, from a single piece for a repair to bulk quantities, and can source more at short notice.

Why MR128 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 MR128 price on WhatsApp.
