This 60 series bearing size chart lists the nominal bore, outside diameter and width of standard 6000–6010 single-row deep groove ball bearings. All dimensions are in millimeters. Use the chart to identify the bearing envelope, then check the full specification before choosing a replacement.
6000–6010 bearing size chart in mm
Dimension sources: LILY Bearing product drawings/specification tables for 6000 through 6010, checked October 16, 2026. The table covers this 11-size range, not the entire 60 series.
Read each size in the order d × D × B. For example, 6004 is 20 × 42 × 12 mm, while 6006 is 30 × 55 × 13 mm.
These dimensions identify the basic envelope. They do not specify load capacity, running accuracy, internal clearance, shaft fit or housing fit.
How to read the bearing number
In this range, the 60 series designation identifies a family of single-row deep groove ball bearings. It does not mean the bearing has a 60 mm bore.
The final two digits of the bearing number identify the bore size. Codes 00–03 are exceptions to the usual multiply-by-five rule:
| Bore code | Bore diameter |
|---|---|
| 00 | 10 mm |
| 01 | 12 mm |
| 02 | 15 mm |
| 03 | 17 mm |
| 04–10 | Code × 5 mm: 20–50 mm |
For 6008, the bore code is 08, giving 8 × 5 = 40 mm. For 6002, code 02 means 15 mm; multiplying it by five would give the wrong answer.
The code does not give you the outside diameter or width by arithmetic. Read those values from the chart or product drawing.
Do 2RS, ZZ and C3 versions have different dimensions?
Standard open, sealed and shielded versions of the same basic bearing number normally retain the same d, D and B. A standard 6004-2RS and 6004-ZZ therefore use the 20 × 42 × 12 mm envelope.
The suffix describes another part of the specification: 2RS commonly indicates two seals, ZZ or 2Z indicates two shields, and C3 identifies increased radial internal clearance.
Closure details vary by manufacturer. Special designs, flanges, extended rings or snap-ring arrangements need their own drawings. A matching envelope does not establish matching speed limits, sealing performance or grease.
6006 vs 6206: the same bore, a different envelope
| Bearing | Bore d | Outside diameter D | Width B |
|---|---|---|---|
| 6006 | 30 mm | 55 mm | 13 mm |
| 6206 | 30 mm | 62 mm | 16 mm |
A 6206 has an outside diameter 7 mm larger and a width 3 mm greater than a 6006. It cannot replace a 6006 in the same unmodified seat. For load ratings, closure options and replacement checks, see our 6206 bearing dimensions and equivalents guide.
Series selection also affects the bearing's internal design and load capability. Do not choose between series by bore diameter alone, or assume that a larger section automatically suits the machine.
How to check a bearing against this chart
Record the complete marking. Include suffixes on the ring, packaging and equipment parts list.
. Check bore, outside diameter and overall ring width. A caliper can help identify a nominal size; fit acceptance requires suitable precision measuring tools.
Inspect the mounting details. Check shoulders, fillet clearance, retaining features and the condition of the seats.
Verify the operating specification. Confirm load ratings, speed, clearance, lubrication and closure type for the exact product.
Do not copy the nominal bearing bore directly into a shaft machining drawing. The required fit depends on the rotating load, temperature, materials and application. A worn shaft or housing also needs assessment before another bearing is installed.
Why load ratings and maximum speeds are not in this chart
The table answers a dimensional question. Load ratings and permissible speeds belong to a particular bearing execution and catalog, rather than the basic number alone.
Adding one universal rating per row would blur that distinction, especially when readers compare open, sealed, stainless or ceramic products. Use the selected product's current data for those checks.

FAQ
Is a 6000 bearing the same thing as the 6000 series?
No. 6000 is one bearing number with dimensions of 10 × 26 × 8 mm. “6000 series” is also used commercially for the broader 60 series family, so check the specific part number.
Can I use a nominal inch shaft with a nearby metric bore?
Check the exact dimensions and required fit. For example, 1 inch equals 25.4 mm, which is 0.4 mm larger than the 25 mm bore of a 6005. Those nominal sizes are not interchangeable.
What if the measured bearing does not match any row?
Check other bearing series and special-width or inch designs. Also confirm that wear, attached spacers or a retaining ring have not affected the measurement. Do not force a near match.
