How the 6014-M model number is decoded
In the 6000-series, the last two digits encode the bore: 6014 carries code 14 = 70 mm (code × 5). The envelope is 70×110×20 mm (2.756×4.331×0.787 in) with a 20.0 mm radial section height, C 39.7 kN, C0 31 kN and Pu 1.32 kN. The open 6014 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 11000 r/min, catalogue mass 700 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
- Fillet radii must clear the 6014-M chamfer so the 20 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Do not preload 6014-M to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- The M suffix on 6014-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 700 g quoted mass includes the heavier cage.
- Open 6014-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 6014-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 70 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.
- Sealed SKF units are filled with a lithium-based grease for general service; food-grade, low-temperature and high-temperature fills are order options and are not field-interchangeable once the unit is sealed.
- For positions that need relubrication, choose the open execution of 6014 and design the housing with a grease path; shielded and sealed versions are intended as fit-and-forget units.
Frequently asked questions
What are the dimensions of 6014-M?
The SKF 6014 M measures 70 mm bore × 110 mm OD × 20 mm width (2.756 × 4.331 × 0.787 in), mass about 700 g. It is open, with no shields or seals.
How does the bore code in 6014 work?
The final two digits of 6014 are bore code 14, multiplied by 5 to give 70 mm.
What is the speed rating of 6014-M?
SKF lists a 13000 r/min thermal reference speed and a 11000 r/min mechanical limiting speed for 6014 M; real limits also depend on lubrication and fits.
What is the difference between 6014-M and a same-bore 62-series bearing?
Section height differs: 6014-M has a 20 mm radial section and C 39.7 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 6014-M?
With a rotating inner ring use roughly k5 on the shaft and H7 in the 110 mm housing; reverse the interference if the outer ring rotates.
