6006 Bearing – Size, Stock & Today’s Price

The 6006 is an extra-light-series deep groove ball bearing with a 30 mm bore, a 55 mm outside diameter and a width of 13 mm. The 60 series is the slimmer choice for a given shaft: a smaller outside diameter and width than the 62, for machines where space and weight matter more than heavy loads.

Its last two digits, 06, multiplied by 5 give the 30 mm bore. A full designation such as 6006-2RS-C3 means a 6006 with rubber seals on both sides and C3 internal clearance, the usual choice for electric motors.

Sharing the same 30 mm bore are the 6206 (30 × 62 × 16 mm), the 6306 (30 × 72 × 19 mm), the 6806 (30 × 42 × 7 mm) and the 6906 (30 × 47 × 9 mm). They all fit a 30 mm shaft, but each needs a different housing, so check the outside diameter and width before you order.

Why 6006 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 6006 price on WhatsApp.

6006 dimensions

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

6006 load and speed ratings

Figures for the open SKF 6006 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 30 mm shaft

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

On a 30 mm shaft, the 6006 carries 90% more load than the slimmer 6906, and the 6206 carries 47% more than the 6006, in a housing 7 mm larger across.

6006 variants

Every 6006 has the same outside dimensions. What changes is how it is sealed, its internal clearance and its material:

• 6006 (open): no shields or seals. For gearboxes and machines where oil or grease reaches the bearing.
• 6006 ZZ / 2Z: metal shields on both sides, greased for life. For clean, fast-running motors and fans.
• 6006 2RS: rubber seals on both sides (DDU at NSK, LLU at NTN). Better against dust and moisture.
• 6006 C3: internal clearance greater than normal, combined with any of the above (e.g. 6006-2RS-C3). The usual choice for electric motors.
• S6006 / SS6006: stainless steel for wet or corrosive conditions, usually marked with an S or SS prefix (SKF uses W). Supplied on request.

Brands available for 6006

Is your 6006 genuine?

Counterfeit bearings are sold in many sizes and brands, including the 6006. 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.
