How the 6026-M model number is decoded
In the 6000-series, the last two digits encode the bore: 6026 carries code 26 = 130 mm (code × 5). The envelope is 130×200×33 mm (5.118×7.874×1.299 in) with a 35.0 mm radial section height, C 112 kN, C0 100 kN and Pu 3.35 kN. The open 6026 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 5600 r/min, catalogue mass 3750 g.
Typical equipment & failure modes
Common applications
- marine deck machinery
- crusher auxiliary drives
- large industrial gearboxes
- heavy conveyor drives
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- Do not preload 6026-M to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Catalogue ratings for 6026-M (C 112 kN, C0 100 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
- The M suffix on 6026-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 3750 g quoted mass includes the heavier cage.
- Open 6026-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 6026-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Assign interference to the rotating ring: on a conventional shaft-mounted 130 mm position the inner ring rotates, so use a k5/m6 shaft seat with an H7 housing — reverse the logic if the outer ring rotates.
- A replacement 6026 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 6026-M?
The SKF 6026 M measures 130 mm bore × 200 mm OD × 33 mm width (5.118 × 7.874 × 1.299 in), mass about 3750 g. It is open, with no shields or seals.
How does the bore code in 6026 work?
The final two digits of 6026 are bore code 26, multiplied by 5 to give 130 mm.
Which fits should I use for 6026-M?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 200 mm housing; reverse the interference if the outer ring rotates.
How heavy is 6026-M?
Catalogue mass is 3750 g for 6026 M; seal and cage executions of the same envelope differ by a few grams.
What internal clearance does 6026-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.
