How the 6222 model number is decoded
6222 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. 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. 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 and blowers
- hoists and winches
- heavy conveyors
- pulp and paper machinery
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- brinelling from static overload or hammering during mounting
- false brinelling from vibration while the shaft is stationary
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.
- Storage matters for open bearings: 6222 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.
- 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.
- Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6200-series position can soften the mixture and leak — clean out the old fill before switching grease types.
- Never mix components between two 6222 units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- 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.
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.
What internal clearance does 6222 have?
Unless a clearance suffix says otherwise, 6222 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.
How should 6222 be mounted?
Apply the mounting force to the ring being fitted: on a 110 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
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, 2RSL) differ from the industry-neutral spelling 6222.
