How the 16064-MA model number is decoded
In the 16000-series, the last two digits encode the bore: 16064 carries code 64 = 320 mm (code × 5). The envelope is 320×480×50 mm (12.598×18.898×1.969 in) with a 80.0 mm radial section height, C 281 kN, C0 405 kN and Pu 8.65 kN. The open 16064 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 2200 r/min, catalogue mass 34000 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.
Typical equipment & failure modes
Common applications
- textile and packaging machinery
- slew and indexing drives
- large industrial gearboxes
- heavy conveyor drives
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- Clearance suffixes follow the seal code in the designation stack (e.g. 16064-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- Deep-groove geometry tolerates only minutes of misalignment; if the 480 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 16064-MA.
- The MA suffix on 16064-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 34000 g quoted mass includes the heavier cage.
- Open 16064-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 16064-MA; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Clearance suffixes follow the seal code in the designation stack (e.g. 16064-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of 16064-MA?
The SKF 16064 MA measures 320 mm bore × 480 mm OD × 50 mm width (12.598 × 18.898 × 1.969 in), mass about 34000 g. It is open, with no shields or seals.
How does the bore code in 16064 work?
The final two digits of 16064 are bore code 64, multiplied by 5 to give 320 mm.
What is the difference between 16064-MA and a same-bore 62-series bearing?
Section height differs: 16064-MA has a 80 mm radial section and C 281 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 16064-MA?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 480 mm housing; reverse the interference if the outer ring rotates.
