How the 6213-M model number is decoded
In the 6200-series, the last two digits encode the bore: 6213 carries code 13 = 65 mm (code × 5). The envelope is 65×120×23 mm (2.559×4.724×0.906 in) with a 27.5 mm radial section height, C 58.5 kN, C0 40.5 kN and Pu 1.73 kN. The open 6213 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 10000 r/min, catalogue mass 1200 g.
Typical equipment & failure modes
Common applications
- industrial electric motors
- gearboxes and speed reducers
- centrifugal and positive-displacement pumps
- material-handling equipment
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- brinelling from static overload or hammer blows during mounting
- false brinelling from vibration while the shaft stands idle
Selection pitfalls — read before you substitute
- At 65 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
- Assign interference to the rotating ring: on a conventional shaft-mounted 65 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.
- The M suffix on 6213-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 1200 g quoted mass includes the heavier cage.
- Open 6213-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 6213-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- At 65 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
Frequently asked questions
What are the dimensions of 6213-M?
The SKF 6213 M measures 65 mm bore × 120 mm OD × 23 mm width (2.559 × 4.724 × 0.906 in), mass about 1200 g. It is open, with no shields or seals.
How does the bore code in 6213 work?
The final two digits of 6213 are bore code 13, multiplied by 5 to give 65 mm.
How heavy is 6213-M?
Catalogue mass is 1200 g for 6213 M; seal and cage executions of the same envelope differ by a few grams.
What load can 6213-M take?
Catalogue values for 6213 M: dynamic C 58.5 kN, static C0 40.5 kN, fatigue limit Pu 1.73 kN. Use C in life calculation and C0 for static checks at 65 mm bore.
