The QJ 211 is a four-point contact ball bearing with a 55 mm bore, a 100 mm outside diameter and a width of 21 mm. A four-point contact ball bearing has a split inner ring, so the ball touches the rings at four points and the bearing carries axial load in both directions. It is usually fitted next to a radial bearing.
The last two digits of the number, 11, give the bore: 11 × 5 = 55 mm. Match the full designation, including any letters after the number, when you replace a bearing.
For the same 55 mm bore we also supply the QJ 311 (55 × 120 × 29 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.
Why QJ 211 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 QJ 211 price on WhatsApp.

Is your QJ 211 genuine?
Counterfeit bearings are sold in many sizes and brands, including the QJ 211. 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.

What size is a QJ 211 bearing?
A QJ 211 measures 55 mm bore × 100 mm outside diameter × 21 mm width.
