How the 16072-MA model number is decoded
In the 16000-series, the last two digits encode the bore: 16072 carries code 72 = 360 mm (code × 5). The envelope is 360×540×57 mm (14.173×21.26×2.244 in) with a 90.0 mm radial section height, C 351 kN, C0 550 kN and Pu 11 kN. The open 16072 MA carries no shields or seals and relies on application lubrication and external sealing. The MA suffix identifies the machined brass cage execution, a separate order number from the pressed-steel version. Limiting speed 1400 r/min, catalogue mass 49000 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.
Typical equipment & failure modes
Common applications
- heavy conveyor drives
- hoists and winches
- industrial fans and blowers
- mill and kiln auxiliaries
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- electrical pitting in VFD-driven motors without shaft grounding
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Do not preload 16072-MA to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Assign interference to the rotating ring: on a conventional shaft-mounted 360 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 MA suffix on 16072-MA 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 49000 g quoted mass includes the heavier cage.
- Open 16072-MA 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 16072-MA; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Do not preload 16072-MA 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 16072-MA?
The SKF 16072 MA measures 360 mm bore × 540 mm OD × 57 mm width (14.173 × 21.26 × 2.244 in), mass about 49000 g. It is open, with no shields or seals.
How does the bore code in 16072 work?
The final two digits of 16072 are bore code 72, multiplied by 5 to give 360 mm.
What load can 16072-MA take?
Catalogue values for 16072 MA: dynamic C 351 kN, static C0 550 kN, fatigue limit Pu 11 kN. Use C in life calculation and C0 for static checks at 360 mm bore.
What is the speed rating of 16072-MA?
SKF lists a 1800 r/min thermal reference speed and a 1400 r/min mechanical limiting speed for 16072 MA; real limits also depend on lubrication and fits.
