How the 6022-M model number is decoded
In the 6000-series, the last two digits encode the bore: 6022 carries code 22 = 110 mm (code × 5). The envelope is 110×170×28 mm (4.331×6.693×1.102 in) with a 30.0 mm radial section height, C 85.2 kN, C0 73.5 kN and Pu 2.6 kN. The open 6022 M carries no shields or seals and relies on application lubrication and external sealing. The M suffix identifies the machined brass cage execution, a separate order number from the pressed-steel version. Limiting speed 7000 r/min, catalogue mass 2300 g.
Typical equipment & failure modes
Common applications
- centrifugal and positive-displacement pumps
- material-handling equipment
- industrial fans
- compressor drives
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- fretting corrosion on a creeping shaft or housing seat
- cage damage from running beyond the limiting speed
Selection pitfalls — read before you substitute
- Do not preload 6022-M to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Mount by heating the inner ring (max 120 °C) — driving 6022-M home through the outer ring or balls brinells the raceways.
- The M suffix on 6022-M denotes a machined brass cage: it is the choice for high speeds, marginal lubrication and shock/vibration duty, and it is temperature-tolerant where polymer cages are not — the 2300 g quoted mass includes the heavier cage.
- Open 6022-M needs external sealing at the arrangement level; in dusty housings its life depends entirely on those external seals and the regreasing schedule.
- Plan a relubrication interval for 6022-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Clearance suffixes follow the seal code in the designation stack (e.g. 6022-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- A replacement 6022 should go onto inspected seats only: SKF mounting guidance calls for clean, burr-free journals within tolerance, since a large share of early failures traces back to damaged or worn seats.
- SKF Explorer deep-groove bearings of this size are produced to tight internal-geometry control; rating revisions between catalogue years do not change the designation, so keep the catalogue edition with the machine documentation.
Frequently asked questions
What are the dimensions of 6022-M?
The SKF 6022 M measures 110 mm bore × 170 mm OD × 28 mm width (4.331 × 6.693 × 1.102 in), mass about 2300 g. It is open, with no shields or seals.
How does the bore code in 6022 work?
The final two digits of 6022 are bore code 22, multiplied by 5 to give 110 mm.
How heavy is 6022-M?
Catalogue mass is 2300 g for 6022 M; seal and cage executions of the same envelope differ by a few grams.
What internal clearance does 6022-M have?
Standard supply is normal CN radial clearance unless a suffix states otherwise; for tight fits or hot shafts SKF lists the C3 execution of the same size — the residual clearance left after mounting is what governs running life.
How long can a greased 6022-M be stored?
Sealed and shielded SKF units carry a finite grease shelf life: SKF recommends first-in-first-out stock rotation and dry, cool, vibration-free storage. Open units ship with rust preventive only and are greased at assembly.
