How the 6022 model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6022 carries bore code 22 = 110 mm. Outside diameter 170 mm and width 28 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
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- At 110 mm bore the ring mass is significant: heat 6022 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 60xx extra-light section at 110 mm bore uses a smaller 170 mm OD than a 6222; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- The open 6022 has no lubricant retention: grease escapes and contaminants migrate straight into the 110×170×28 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6022 units.
- Shaft and housing fillets must clear the bearing chamfer so the 28 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- 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.
- The open 6022 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6022-2Z (shields) and 6022-2RSH (contact seals), not suffix-free 6022.
- 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 bearing?
A 6022 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 an open bearing with no seals or shields.
How should 6022 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 lubrication does 6022 need?
The open 6022 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
How does the 6022 bore code work?
The last two digits of 6022 are bore code 22, giving 22 × 5 = 110 mm bore. The 170 mm outside diameter and 28 mm width follow the ISO 15 diameter series, not the bore code alone.
What is the SKF designation and catalogue data for 6022?
In the SKF Rolling Bearings catalogue this size is listed as 6022 — the open (unsealed) execution, 110×170×28 mm per ISO 15. Quoted values: C 85.2 kN, C0 73.5 kN, Pu 2.6 kN, limiting speed 5000 r/min, mass 1950 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6022.
