How the 6010 model number is decoded
6010 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 10 by five gives the 50 mm bore; the 80 mm outside diameter and 16 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 50 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. 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
- industrial fans
- industrial electric motors
- centrifugal and positive-displacement pumps
- gearboxes and speed reducers
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Interference on a 50 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6010 with C3 clearance and re-check the residual value after mounting.
- The 60xx extra-light section at 50 mm bore uses a smaller 80 mm OD than a 6210; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- The open 6010 has no lubricant retention: grease escapes and contaminants migrate straight into the 50×80×16 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6010 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.
- Vibration during standstill brinells the raceways of a 50 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- The open 6010 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6010-2Z (shields) and 6010-2RSH (contact seals), not suffix-free 6010.
- The 22.9/16 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 6010 bearing?
A 6010 deep-groove ball bearing has a 50 mm bore, 80 mm outer diameter and 16 mm width (1.969 × 3.15 × 0.63 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How does the 6000 compare with other series at the same 50 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (80×16 mm, 15.0 mm radial section) at 50 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6010 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6010 uses the same ISO 15 envelope (50×80×16 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 6010 have?
Unless a clearance suffix says otherwise, 6010 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 6010 and verify the residual clearance after mounting.
What is the SKF designation and catalogue data for 6010?
In the SKF Rolling Bearings catalogue this size is listed as 6010 — the open (unsealed) execution, 50×80×16 mm per ISO 15. Quoted values: C 22.9 kN, C0 16 kN, Pu 0.71 kN, limiting speed 11000 r/min, mass 260 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6010.
