How the 6222 model number is decoded
In the 6200-series (ISO 15 diameter series 2) the last two digits encode the bore: 6222 carries bore code 22 = 110 mm. Outside diameter 200 mm and width 38 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 110 mm shaft, typical catalogue practice is a m6 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
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- Mount this 110 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 62xx light series is the default general-purpose section at 110 mm bore; before upgrading to a 6322 for extra capacity, confirm the housing accepts a 200 mm OD and 38 mm width — it is not a drop-in swap.
- The open 6222 has no lubricant retention: grease escapes and contaminants migrate straight into the 110×200×38 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 6222 units.
- A 110 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
- The open 6222 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6222-2Z (shields) and 6222-2RSH (contact seals), not suffix-free 6222.
- The 151/118 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 6222 bearing?
A 6222 deep-groove ball bearing has a 110 mm bore, 200 mm outer diameter and 38 mm width (4.331 × 7.874 × 1.496 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields. Geometry-based estimated mass is about 4249 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
How does the 6222 bore code work?
The last two digits of 6222 are bore code 22, giving 22 × 5 = 110 mm bore. The 200 mm outside diameter and 38 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 6222 mean?
A bare 6222 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 110 mm bore?
The '2' is the light diameter series: 200×38 mm with a 45.0 mm radial section at 110 mm bore. A 6322 on the same bore is larger and higher-rated; a 6022 is smaller and lower-rated.
What is the SKF designation and catalogue data for 6222?
In the SKF Rolling Bearings catalogue this size is listed as 6222 — the open (unsealed) execution, 110×200×38 mm per ISO 15. Quoted values: C 151 kN, C0 118 kN, Pu 4 kN, limiting speed 4300 r/min, mass 4450 g. Brand suffixes (2Z, 2RSH) differ from the industry-neutral spelling 6222.
