How the 6036-M model number is decoded
In the 6000-series, the last two digits encode the bore: 6036 carries code 36 = 180 mm (code × 5). The envelope is 180×280×46 mm (7.087×11.024×1.811 in) with a 50.0 mm radial section height, C 190 kN, C0 200 kN and Pu 5.6 kN. The open 6036 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 4000 r/min, catalogue mass 10500 g.
Typical equipment & failure modes
Common applications
- crusher auxiliary drives
- large industrial gearboxes
- heavy conveyor drives
- hoists and winches
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
- Catalogue ratings for 6036-M (C 190 kN, C0 200 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
- Assign interference to the rotating ring: on a conventional shaft-mounted 180 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 M suffix on 6036-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 10500 g quoted mass includes the heavier cage.
- Open 6036-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 6036-M; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- The fatigue load limit is 5.6 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- Where two 6036 bearings share one shaft in a preloaded or matched arrangement, order both from the same production lot; catalogue figures describe a single bearing, not a matched set.
- For positions that need relubrication, choose the open execution of 6036 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 6036-M?
The SKF 6036 M measures 180 mm bore × 280 mm OD × 46 mm width (7.087 × 11.024 × 1.811 in), mass about 10500 g. It is open, with no shields or seals.
How does the bore code in 6036 work?
The final two digits of 6036 are bore code 36, multiplied by 5 to give 180 mm.
Which fits should I use for 6036-M?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 280 mm housing; reverse the interference if the outer ring rotates.
How heavy is 6036-M?
Catalogue mass is 10500 g for 6036 M; seal and cage executions of the same envelope differ by a few grams.
What internal clearance does 6036-M have?
Standard supply is normal CN radial clearance unless a suffix states otherwise; for tight fits or hot shafts SKF lists the C3 execution of the same size — the residual clearance left after mounting is what governs running life.
