6208 Bearing – Size, Stock & Today’s Price

The 6208 is a light-series deep groove ball bearing with a 40 mm bore, an 80 mm outside diameter and a width of 18 mm. The 62 series is the everyday workhorse of deep groove bearings, balancing size and load capacity. It is the series most electric motors, pumps and gearboxes are built around.

Its last two digits, 08, multiplied by 5 give the 40 mm bore. A full designation such as 6208-2RS-C3 means a 6208 with rubber seals on both sides and C3 internal clearance, the usual choice for electric motors.

Sharing the same 40 mm bore are the 6008 (40 × 68 × 15 mm), the 6308 (40 × 90 × 23 mm), the 6808 (40 × 52 × 7 mm) and the 6908 (40 × 62 × 12 mm). They all fit a 40 mm shaft, but each needs a different housing, so check the outside diameter and width before you order.

Why 6208 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.

So we quote today’s price for each brand rather than list one number. Ask for the 6208 price on WhatsApp.

Dimensions are the ISO 15 standard size, the same in every brand and seal type.

6208 load and speed ratings

Figures for the open SKF 6208 from SKF’s online catalogue (checked 9 Oct 2026). Other brands publish slightly different ratings for the same size. Sealed (2RS) versions have a lower limiting speed. SKF data sheet.

Other bearings for a 40 mm shaft

Same bore, different series: a bigger bearing carries more load but needs a bigger housing.

On a 40 mm shaft, the 6208 carries 83% more load than the slimmer 6008, and the 6308 carries 30% more than the 6208, in a housing 10 mm larger across.

6208 variants

Every 6208 has the same outside dimensions. What changes is how it is sealed, its internal clearance and its material:

• 6208 (open): no shields or seals. For gearboxes and machines where oil or grease reaches the bearing.
• 6208 ZZ / 2Z: metal shields on both sides, greased for life. For clean, fast-running motors and fans.
• 6208 2RS: rubber seals on both sides (DDU at NSK, LLU at NTN). Better against dust and moisture.
• 6208 C3: internal clearance greater than normal, combined with any of the above (e.g. 6208-2RS-C3). The usual choice for electric motors.
• S6208 / SS6208: stainless steel for wet or corrosive conditions, usually marked with an S or SS prefix (SKF uses W). Supplied on request.

Brands available for 6208

Is your 6208 genuine?

Counterfeit bearings are sold in many sizes and brands, including the 6208. 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.
