How the 6022-ZZ model number is decoded
6022-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 extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 22 by five gives the 110 mm bore; the 170 mm outside diameter and 28 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 6022-2Z.
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
- 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.
- Choosing the 60xx extra-light section saves radial space at 110 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 6222 before committing to the smaller envelope.
- Do not wash 6022-ZZ in solvent before mounting: the grease inside the shielded cavity is the service fill, and solvent creeping past the shield gap strips it out.
- Shielded 6022-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.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- 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.
- SKF spells the shielded version 6022-2Z (one shield: 6022-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 6022-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 6022-2Z for high-contamination positions.
- The 85.2/73.5 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 6022-ZZ bearing?
A 6022-ZZ deep-groove ball bearing has a 110 mm bore, 170 mm outer diameter and 28 mm width (4.331 × 6.693 × 1.102 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
What does the ZZ suffix on 6022-ZZ mean?
ZZ means two non-contact sheet-metal shields, one each side. They retain factory grease and block coarse particles with little friction, but do not seal against liquids, fine dust or pressure washing.
How does the 6000 compare with other series at the same 110 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (170×28 mm, 30.0 mm radial section) at 110 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6022 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6022 uses the same ISO 15 envelope (110×170×28 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 is the SKF designation and catalogue data for 6022-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6022-2Z — two non-contact sheet-metal shields, 110×170×28 mm per ISO 15. Quoted values: C 85.2 kN, C0 73.5 kN, Pu 2.6 kN, limiting speed 4000 r/min, mass 2050 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6022-ZZ.
