How the 6060-M model number is decoded
In the 6000-series, the last two digits encode the bore: 6060 carries code 60 = 300 mm (code × 5). The envelope is 300×460×74 mm (11.811×18.11×2.913 in) with a 80.0 mm radial section height, C 358 kN, C0 500 kN and Pu 10.8 kN. The open 6060 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 2400 r/min, catalogue mass 44000 g.
Typical equipment & failure modes
Common applications
- robotics and automation joints
- lay shafts and idler shafts
- textile and packaging machinery
- slew and indexing drives
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- brinelling from static overload or hammer blows during mounting
- false brinelling from vibration while the shaft stands idle
Selection pitfalls — read before you substitute
- Clearance suffixes follow the seal code in the designation stack (e.g. 6060-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- Mount by heating the inner ring (max 120 °C) — driving 6060-M home through the outer ring or balls brinells the raceways.
- The M suffix on 6060-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 44000 g quoted mass includes the heavier cage.
- Open 6060-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 6060-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 300 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.
Frequently asked questions
What are the dimensions of 6060-M?
The SKF 6060 M measures 300 mm bore × 460 mm OD × 74 mm width (11.811 × 18.11 × 2.913 in), mass about 44000 g. It is open, with no shields or seals.
How does the bore code in 6060 work?
The final two digits of 6060 are bore code 60, multiplied by 5 to give 300 mm.
How heavy is 6060-M?
Catalogue mass is 44000 g for 6060 M; seal and cage executions of the same envelope differ by a few grams.
What load can 6060-M take?
Catalogue values for 6060 M: dynamic C 358 kN, static C0 500 kN, fatigue limit Pu 10.8 kN. Use C in life calculation and C0 for static checks at 300 mm bore.
