NU 2218 Bearing – Size, Stock & Today’s Price

The NU 2218 is a cylindrical roller bearing with a 90 mm bore, a 160 mm outside diameter and a width of 40 mm. Cylindrical roller bearings carry heavy radial loads, because the rollers touch the raceways along a line rather than at a point, and they suit high speeds. Depending on the design, they let the shaft move slightly along its length or locate it in one or both directions.

The last two digits of the number, 18, give the bore: 18 × 5 = 90 mm. Match the full designation, including any letters after the number, when you replace a bearing.

For the same 90 mm bore we also supply the NU 1018 and N 1018 (90 × 140 × 24 mm), the NN 3018 (90 × 140 × 37 mm), the NU 218, NUP 218 and NJ 218 (90 × 160 × 30 mm) and the NU 318, N 318 and NUP 318 (90 × 190 × 43 mm). They fit the same shaft but have a different outside diameter or width, so they need a different housing: check both before you order. The same 90 × 160 × 40 mm size is also listed as the NUP 2218, NJ 2218 (a different rib or cage design): tell us the letters on the old bearing.

Why NU 2218 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: clearance (C3, C4), tapered bore (K), cage and special-design versions are priced differently from the standard one.
• 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 NU 2218 price on WhatsApp.

NU 2218 variants

Every NU 2218 has the same outside dimensions. These are the versions you will meet most often:

• NU 2218: Two ribs on the outer ring and none on the inner ring: a floating bearing that lets the shaft move along its length.
• Letters after the number: On SKF bearings EC marks the optimised internal design and the cage letter follows: J pressed steel, P polyamide, M machined brass. FAG writes E-XL and uses cage codes such as M1 or TVP2.
• Other designs: NU and N float, NJ and NF locate one way, NUP locates both ways. Tell us the design letters on the old bearing.

Is your NU 2218 genuine?

Counterfeit bearings are sold in many sizes and brands, including the NU 2218. 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.
