How the 6032-M model number is decoded
In the 6000-series, the last two digits encode the bore: 6032 carries code 32 = 160 mm (code × 5). The envelope is 160×240×38 mm (6.299×9.449×1.496 in) with a 40.0 mm radial section height, C 143 kN, C0 143 kN and Pu 4.3 kN. The open 6032 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 4800 r/min, catalogue mass 6000 g.
Typical equipment & failure modes
Common applications
- industrial fans and blowers
- mill and kiln auxiliaries
- pulp and paper machinery
- marine deck machinery
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
- Assign interference to the rotating ring: on a conventional shaft-mounted 160 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.
- Mount by heating the inner ring (max 120 °C) — driving 6032-M home through the outer ring or balls brinells the raceways.
- The M suffix on 6032-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 6000 g quoted mass includes the heavier cage.
- Open 6032-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 6032-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Mount by heating the inner ring (max 120 °C) — driving 6032-M home through the outer ring or balls brinells the raceways.
- 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.
- SKF date-codes its packaging, and greased sealed or shielded bearings carry a finite shelf life: rotate stock first-in-first-out and store boxes dry, cool and away from vibration.
Frequently asked questions
What are the dimensions of 6032-M?
The SKF 6032 M measures 160 mm bore × 240 mm OD × 38 mm width (6.299 × 9.449 × 1.496 in), mass about 6000 g. It is open, with no shields or seals.
How does the bore code in 6032 work?
The final two digits of 6032 are bore code 32, multiplied by 5 to give 160 mm.
How long can a greased 6032-M be stored?
Sealed and shielded SKF units carry a finite grease shelf life: SKF recommends first-in-first-out stock rotation and dry, cool, vibration-free storage. Open units ship with rust preventive only and are greased at assembly.
What load can 6032-M take?
Catalogue values for 6032 M: dynamic C 143 kN, static C0 143 kN, fatigue limit Pu 4.3 kN. Use C in life calculation and C0 for static checks at 160 mm bore.
What is the speed rating of 6032-M?
SKF lists a 5600 r/min thermal reference speed and a 4800 r/min mechanical limiting speed for 6032 M; real limits also depend on lubrication and fits.
