How the 6260-M model number is decoded
In the 6200-series, the last two digits encode the bore: 6260 carries code 60 = 300 mm (code × 5). The envelope is 300×540×85 mm (11.811×21.26×3.346 in) with a 120.0 mm radial section height, C 462 kN, C0 670 kN and Pu 13.7 kN. The open 6260 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 2000 r/min, catalogue mass 88500 g.
Typical equipment & failure modes
Common applications
- mill and kiln auxiliaries
- pulp and paper machinery
- marine deck machinery
- crusher auxiliary 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
- Catalogue ratings for 6260-M (C 462 kN, C0 670 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.
- Fillet radii must clear the 6260-M chamfer so the 85 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- The M suffix on 6260-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 88500 g quoted mass includes the heavier cage.
- Open 6260-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 6260-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Do not preload 6260-M to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
Frequently asked questions
What are the dimensions of 6260-M?
The SKF 6260 M measures 300 mm bore × 540 mm OD × 85 mm width (11.811 × 21.26 × 3.346 in), mass about 88500 g. It is open, with no shields or seals.
How does the bore code in 6260 work?
The final two digits of 6260 are bore code 60, multiplied by 5 to give 300 mm.
Which fits should I use for 6260-M?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 540 mm housing; reverse the interference if the outer ring rotates.
How heavy is 6260-M?
Catalogue mass is 88500 g for 6260 M; seal and cage executions of the same envelope differ by a few grams.
