How the 6214-M model number is decoded
In the 6200-series, the last two digits encode the bore: 6214 carries code 14 = 70 mm (code × 5). The envelope is 70×125×24 mm (2.756×4.921×0.945 in) with a 27.5 mm radial section height, C 60.5 kN, C0 45 kN and Pu 1.9 kN. The open 6214 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 1300 g.
Typical equipment & failure modes
Common applications
- compressor drives
- machine tool auxiliaries
- agricultural gearboxes
- industrial electric motors
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- cage damage from running beyond the limiting speed
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Mount by heating the inner ring (max 120 °C) — driving 6214-M home through the outer ring or balls brinells the raceways.
- At 70 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.
- The M suffix on 6214-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 1300 g quoted mass includes the heavier cage.
- Open 6214-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 6214-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Do not preload 6214-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 6214-M?
The SKF 6214 M measures 70 mm bore × 125 mm OD × 24 mm width (2.756 × 4.921 × 0.945 in), mass about 1300 g. It is open, with no shields or seals.
How does the bore code in 6214 work?
The final two digits of 6214 are bore code 14, multiplied by 5 to give 70 mm.
What is the difference between 6214-M and a same-bore 62-series bearing?
Section height differs: 6214-M has a 27.5 mm radial section and C 60.5 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 6214-M?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 125 mm housing; reverse the interference if the outer ring rotates.
