The 608 is a small deep groove ball bearing with an 8 mm bore, a 22 mm outside diameter and a width of 7 mm. Small deep groove bearings like this are made in very large numbers for power tools, small motors, fans and hobby uses, and a one-millimetre difference in size matters.
Below a 10 mm bore the numbering changes: the last digit is the bore itself, so the 608 has an 8 mm bore. That is why it is worth measuring a small bearing before you order: a 608 and its neighbours can differ by a single millimetre.
Why 608 prices vary
- Genuine or copy: fakes sell far below the real price and fail early. We sell only genuine bearings.
- Brand and origin: each maker, and each country of manufacture, is priced differently.
- Version: sealed, shielded, C3, stainless and low-noise versions cost more than the open bearing.
- Quantity: bulk and repeat orders are priced lower.

608 variants
Every 608 has the same outside dimensions. What changes is how it is sealed, its internal clearance and its material:
- 608 (open): no shields or seals. For gearboxes and machines where oil or grease reaches the bearing.
- 608 ZZ / 2Z: metal shields on both sides, greased for life. For clean, fast-running motors and fans.
- 608 2RS: rubber seals on both sides (DDU at NSK, LLU at NTN). Better against dust and moisture.
- 608 C3: internal clearance greater than normal, combined with any of the above (e.g. 608-2RS-C3). The usual choice for electric motors.
- S608 / SS608: stainless steel for wet or corrosive conditions, usually marked with an S or SS prefix (SKF uses W). Supplied on request.

Is your 608 genuine?
Counterfeit bearings are sold in many sizes and brands, including the 608. Check that the marking on the ring matches the box exactly, that the brand’s own suffix style is used, and be wary of prices far below the market. How to spot a fake bearing.
