Bearing Size Chart: 6000, 6200, 6300 Series

A bearing size chart lists the three boundary dimensions — bore (inner diameter), outside diameter, and width — for every model in a series. This chart covers the three most common metric deep groove ball bearing series: 6000, 6200, and 6300, with 63 standard models from 10 mm to 100 mm bore.

All dimensions follow ISO 15:2011 boundary standards, so each model is interchangeable with the equivalent SKF, FAG, NSK, NTN, or Timken designation of the same number.

How to Read This Bearing Size Chart

1. Bore (ID) — the shaft diameter. The most important dimension for identification.
2. Outside diameter (OD) — the housing bore size.
3. Width (W) — the axial thickness of the bearing.
4. Open / ZZ / 2RS — which closure variants are available for each model. The closure does not change the boundary dimensions.

For bores from 20 mm upward, the last two digits of the model number × 5 give the bore: 6208 = 08 × 5 = 40 mm. Below 20 mm the code is non-linear (6201 = 12 mm, 6202 = 15 mm, 6203 = 17 mm).

6000 Series Bearing Size Chart

6000 Series bearings are extra light duty — compact, high-speed. Bore range 10–100 mm. Typical uses: Small motors, power tools, appliances. All dimensions follow ISO 15:2011 boundary standards.

6200 Series Bearing Size Chart

6200 Series bearings are light duty — the industrial default. Bore range 10–100 mm. Typical uses: Electric motors, pumps, gearboxes. All dimensions follow ISO 15:2011 boundary standards.

6300 Series Bearing Size Chart

6300 Series bearings are medium duty — higher load capacity. Bore range 10–130 mm. Typical uses: Larger motors, gearboxes, conveyors. All dimensions follow ISO 15:2011 boundary standards.

How to Choose Between 6000, 6200, and 6300

The same bore is available in all three series, but with different OD and width — and therefore different load capacity:

• 6000 series — extra light duty. Smallest OD and width for a given bore. Choose where space and weight are limited and loads are light.
• 6200 series — light duty. The most widely used series in industry; the default for electric motors, pumps, and general machinery.
• 6300 series — medium duty. Larger OD and width for the same bore, giving higher load ratings. Choose when a 6200-series bearing is borderline on load.

Example: 6205, 6305, and 6005 all have a 25 mm bore, but their OD and width differ (6205 = 52×15 mm, 6305 = 62×17 mm, 6005 = 47×12 mm). They are not interchangeable — the housing bore and shaft length decide which one fits.

Measuring a Bearing That Has No Part Number

If the marking is worn off, measure the bore, OD, and width with a caliper and match all three against the tables above. Two series can share a bore, so all three dimensions are required. See how to measure a bearing size for the full procedure.
