How the 6000 model number is decoded
In the 6000-series (diameter series 0 of ISO 15) 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. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- domestic appliances
- power tools
- small fans and blowers
- garden equipment
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
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).
- Choosing the 60xx extra-light section saves radial space at 10 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6200 before committing to the smaller envelope.
- 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.
- Storage matters for open bearings: 6000 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- Do not quieten a noisy bearing by preloading it: the 6000-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6000-C3. No clearance suffix means normal CN clearance.
- 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.
Are 6000 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6000 uses the same ISO 15 envelope (10×26×8 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What internal clearance does 6000 have?
Unless a clearance suffix says otherwise, 6000 is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6000 and verify the residual clearance after mounting.
How should 6000 be mounted?
Apply the mounting force to the ring being fitted: on a 10 mm shaft seat the press load must pass through the inner-ring face only. A fitting sleeve and an arbor press are normally sufficient at this size. Never strike the outer ring, the cage or the seals.
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.
