How the 6212-M model number is decoded
In the 6200-series, the last two digits encode the bore: 6212 carries code 12 = 60 mm (code × 5). The envelope is 60×110×22 mm (2.362×4.331×0.866 in) with a 25.0 mm radial section height, C 55.3 kN, C0 36 kN and Pu 1.53 kN. The open 6212 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 8000 r/min, catalogue mass 930 g.
Typical equipment & failure modes
Common applications
- agricultural gearboxes
- industrial electric motors
- gearboxes and speed reducers
- centrifugal and positive-displacement pumps
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- false brinelling from vibration while the shaft stands idle
- fretting corrosion on a creeping shaft or housing seat
Selection pitfalls — read before you substitute
- Do not preload 6212-M to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Deep-groove geometry tolerates only minutes of misalignment; if the 110 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 6212-M.
- The M suffix on 6212-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 930 g quoted mass includes the heavier cage.
- Open 6212-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 6212-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Do not preload 6212-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 6212-M?
The SKF 6212 M measures 60 mm bore × 110 mm OD × 22 mm width (2.362 × 4.331 × 0.866 in), mass about 930 g. It is open, with no shields or seals.
How does the bore code in 6212 work?
The final two digits of 6212 are bore code 12, multiplied by 5 to give 60 mm.
How heavy is 6212-M?
Catalogue mass is 930 g for 6212 M; seal and cage executions of the same envelope differ by a few grams.
What load can 6212-M take?
Catalogue values for 6212 M: dynamic C 55.3 kN, static C0 36 kN, fatigue limit Pu 1.53 kN. Use C in life calculation and C0 for static checks at 60 mm bore.
