How the 6222-ZZ model number is decoded
6222-ZZ carries two non-contact sheet-steel shields that hold the factory grease in and keep coarse debris out; they do not seal against liquids. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 22 by five gives the 110 mm bore; the 200 mm outside diameter and 38 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 110 mm shaft under normal load, catalogue practice seats it on a m6 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. SKF's own suffix is 2Z (this page's industry-neutral spelling is -ZZ); catalogue number 6222-2Z.
Typical equipment & failure modes
Common applications
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
- hoists and winches
Known failure patterns
- fine-particle abrasion when non-contact shields let dust past in dirty duty
- grease aging in the shield-for-life cavity with no relubrication path
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- At 110 mm bore the ring mass is significant: heat 6222 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
- 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.
- ZZ shields are non-contact: 6222-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6222-2RS for that.
- Shielded 6222-ZZ units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
- Shaft and housing fillets must clear the bearing chamfer so the 38 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- Never mix components between two 6222-ZZ units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- SKF spells the shielded version 6222-2Z (one shield: 6222-Z), not "-ZZ": the suffix language differs by brand even though the ISO envelope is identical, so quote the brand designation when ordering.
- The single-shield execution 6222-Z is a distinct order number in catalogue 17000: it suits open gears or oil-bath arrangements where the unshielded face faces the lubricant, and it is not interchangeable with the double-shield 6222-2Z for high-contamination positions.
- 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-ZZ bearing?
A 6222-ZZ 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 fitted with two non-contact metallic shields.
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.
Are 6222 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6222 uses the same ISO 15 envelope (110×200×38 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting. Seal suffixes also differ by brand (2RS, DDU, LLU, 2RSL and similar).
What internal clearance does 6222-ZZ have?
Unless a clearance suffix says otherwise, 6222-ZZ 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 6222 and verify the residual clearance after mounting.
What is the SKF designation and catalogue data for 6222-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6222-2Z — two non-contact sheet-metal shields, 110×200×38 mm per ISO 15. Quoted values: C 151 kN, C0 118 kN, Pu 4 kN, limiting speed 3400 r/min, mass 4600 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6222-ZZ.
