The 6210 is a light-series deep groove ball bearing with a 50 mm bore, a 90 mm outside diameter and a width of 20 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, 10, multiplied by 5 give the 50 mm bore. A full designation such as 6210-2RS-C3 means a 6210 with rubber seals on both sides and C3 internal clearance, the usual choice for electric motors.
Sharing the same 50 mm bore are the 6010 (50 × 80 × 16 mm), the 6310 (50 × 110 × 27 mm), the 6810 (50 × 65 × 7 mm) and the 6910 (50 × 72 × 12 mm). They all fit a 50 mm shaft, but each needs a different housing, so check the outside diameter and width before you order.
Why 6210 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 6210 price on WhatsApp.

Other bearings for a 50 mm shaft
Same bore, different series: a bigger bearing carries more load but needs a bigger housing.
| Bearing | Size (mm) | Dynamic load C |
|---|---|---|
| 6010 | 50 × 80 × 16 | 22.9 kN |
| 6210 | 50 × 90 × 20 | 37.1 kN |
| 6310 | 50 × 110 × 27 | 65 kN |
On a 50 mm shaft, the 6210 carries 62% more load than the slimmer 6010, and the 6310 carries 75% more than the 6210, in a housing 20 mm larger across.
6210 variants
Every 6210 has the same outside dimensions. What changes is how it is sealed, its internal clearance and its material:
- 6210 (open): no shields or seals. For gearboxes and machines where oil or grease reaches the bearing.
- 6210 ZZ / 2Z: metal shields on both sides, greased for life. For clean, fast-running motors and fans.
- 6210 2RS: rubber seals on both sides (DDU at NSK, LLU at NTN). Better against dust and moisture.
- 6210 C3: internal clearance greater than normal, combined with any of the above (e.g. 6210-2RS-C3). The usual choice for electric motors.
- S6210 / SS6210: stainless steel for wet or corrosive conditions, usually marked with an S or SS prefix (SKF uses W). Supplied on request.

Is your 6210 genuine?
Counterfeit bearings are sold in many sizes and brands, including the 6210. 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.

Questions
6210 bearing: frequently asked
What size is a 6210 bearing?
A 6210 measures 50 mm bore × 90 mm outside diameter × 20 mm width. The size is the same in every brand and seal type.
What is the SKF, FAG or NSK equivalent of 6210 2RS C3?
SKF writes it 6210-2RS1/C3, FAG writes it 6210-2RSR-C3 and NSK 6210DDUC3, NTN 6210LLUC3 and KOYO 6210-2RS C3. All are the same 50 × 90 × 20 mm size with rubber seals on both sides and C3 clearance.
Can I use a 6310 instead of a 6210?
Not without changing the housing. Both have a 50 mm bore, but the 6310 is 110 mm across and 27 mm wide, against 90 × 20 mm for the 6210.
What load can a 6210 bearing carry?
SKF rates the open 6210 at a dynamic load rating (C) of 37.1 kN and a static load rating (C0) of 23.2 kN, with a limiting speed of 10,000 r/min. Other brands publish similar figures. How much load it can carry in service also depends on speed, lubrication and the life you need.
