How the 6000 model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6000 carries bore code 00 = 10 mm. Codes 00–03 follow the 10/12/15/17 mm exception table rather than code × 5. Outside diameter 26 mm and width 8 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 10 mm shaft, typical catalogue practice is a j5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude.
Typical equipment & failure modes
Common applications
- fractional-horsepower electric motors
- domestic appliances
- power tools
- small fans and blowers
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- brinelling from static overload or hammering during mounting
Selection pitfalls — read before you substitute
- Bore codes 00–03 use the exception table: 6000 fits a 10 mm shaft — the code × 5 mnemonic does not apply below code 04 (it would imply 0 mm for code 00).
- The 60xx extra-light section at 10 mm bore uses a smaller 26 mm OD than a 6200; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- The open 6000 has no lubricant retention: grease escapes and contaminants migrate straight into the 10×26×8 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6000 units.
- Shaft and housing fillets must clear the bearing chamfer so the 8 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- The open 6000 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6000-2Z (shields) and 6000-2RSH (contact seals), not suffix-free 6000.
- The 4.75/1.96 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6000 bearing?
A 6000 deep-groove ball bearing has a 10 mm bore, 26 mm outer diameter and 8 mm width (0.394 × 1.024 × 0.315 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
Why does 6000 not follow the bore-code × 5 rule?
Codes 00–03 use the exception table (10, 12, 15 and 17 mm): 6000 with code 00 has a 10 mm bore. The code × 5 convention starts at code 04 (20 mm).
What does no suffix on 6000 mean?
A bare 6000 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 6000 compare with other series at the same 10 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (26×8 mm, 8.0 mm radial section) at 10 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
What is the SKF designation and catalogue data for 6000?
In the SKF Rolling Bearings catalogue this size is listed as 6000 — the open (unsealed) execution, 10×26×8 mm per ISO 15. Quoted values: C 4.75 kN, C0 1.96 kN, Pu 0.083 kN, limiting speed 40000 r/min, mass 19 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6000.
