How the 60-560-N1MAS model number is decoded
In the large-bore 6000-series, the bore is written directly after the slash as 560 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 560×820×115 mm (22.047×32.283×4.528 in) with a 130.0 mm radial section height, C 663 kN, C0 1370 kN and Pu 22 kN. The open 60/560 N1MAS carries no shields or seals and relies on application lubrication and external sealing. The N1MAS suffix identifies the machined brass cage execution (special cage variant for this large thin-section size), a separate order number from the pressed-steel version. Limiting speed 1200 r/min, catalogue mass 210000 g.
Typical equipment & failure modes
Common applications
- clutch and transmission assemblies
- robotics and automation joints
- lay shafts and idler shafts
- textile and packaging machinery
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- cage damage from running beyond the limiting speed
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- At 560 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
- Do not preload 60-560-N1MAS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- The N1MAS execution of 60-560-N1MAS is a special machined-brass cage variant listed in catalogue 17000 for the largest thin-section sizes; confirm the exact cage feature set with SKF when ordering and servicing.
- The N1MAS suffix on 60-560-N1MAS 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 210000 g quoted mass includes the heavier cage.
- Open 60-560-N1MAS 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 60-560-N1MAS; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
Frequently asked questions
What are the dimensions of 60-560-N1MAS?
The SKF 60/560 N1MAS measures 560 mm bore × 820 mm OD × 115 mm width (22.047 × 32.283 × 4.528 in), mass about 210000 g. It is open, with no shields or seals.
Why is there a slash in the designation 60/560 N1MAS?
The slash writes a bore that falls outside the two-digit code table: 60/560 means 560 mm bore. The site slug 60-560-N1MAS replaces the slash with a hyphen.
What load can 60-560-N1MAS take?
Catalogue values for 60/560 N1MAS: dynamic C 663 kN, static C0 1370 kN, fatigue limit Pu 22 kN. Use C in life calculation and C0 for static checks at 560 mm bore.
What is the speed rating of 60-560-N1MAS?
SKF lists a 1400 r/min thermal reference speed and a 1200 r/min mechanical limiting speed for 60/560 N1MAS; real limits also depend on lubrication and fits.
