How the 6207 model number is decoded
In the 6200-series (ISO 15 diameter series 2) the last two digits encode the bore: 6207 carries bore code 07 = 35 mm. Outside diameter 72 mm and width 17 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 35 mm shaft, typical catalogue practice is a k5 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
- conveyors and drives
- agricultural equipment
- fans and blowers
- electric motors
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
- At a 35 mm bore, a shaft-seat burr or an overtight setscrew can score the thin inner ring of 6207; check shaft finish and runout (target Ra ≤ 1.6 µm) before pressing it home.
- The 62xx light series is the default general-purpose section at 35 mm bore; before upgrading to a 6307 for extra capacity, confirm the housing accepts a 72 mm OD and 17 mm width — it is not a drop-in swap.
- The open 6207 has no lubricant retention: grease escapes and contaminants migrate straight into the 35×72×17 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6200-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6207 units.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 72 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6207.
- The open 6207 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6207-2Z (shields) and 6207-2RSH (contact seals), not suffix-free 6207.
- The 27/15.3 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 6207 bearing?
A 6207 deep-groove ball bearing has a 35 mm bore, 72 mm outer diameter and 17 mm width (1.378 × 2.835 × 0.669 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields. Geometry-based estimated mass is about 270 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
How does the 6207 bore code work?
The last two digits of 6207 are bore code 07, giving 07 × 5 = 35 mm bore. The 72 mm outside diameter and 17 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 6207 mean?
A bare 6207 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 6200 compare with other series at the same 35 mm bore?
The '2' is the light diameter series: 72×17 mm with a 18.5 mm radial section at 35 mm bore. A 6307 on the same bore is larger and higher-rated; a 6007 is smaller and lower-rated.
What is the SKF designation and catalogue data for 6207?
In the SKF Rolling Bearings catalogue this size is listed as 6207 — the open (unsealed) execution, 35×72×17 mm per ISO 15. Quoted values: C 27 kN, C0 15.3 kN, Pu 0.655 kN, limiting speed 13000 r/min, mass 290 g. Brand suffixes (2Z, 2RSH) differ from the industry-neutral spelling 6207.
