How the 60-800-N1MAS model number is decoded
In the large-bore 6000-series, the bore is written directly after the slash as 800 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 800×1150×155 mm (31.496×45.276×6.102 in) with a 175.0 mm radial section height, C 1010 kN, C0 2550 kN and Pu 34.5 kN. The open 60/800 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 750 r/min, catalogue mass 523000 g.
Typical equipment & failure modes
Common applications
- large industrial gearboxes
- heavy conveyor drives
- hoists and winches
- industrial fans and blowers
Known failure patterns
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
- raceway smearing under marginal lubrication at start-up
- electrical pitting in VFD-driven motors without shaft grounding
Selection pitfalls — read before you substitute
- Do not preload 60-800-N1MAS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- The fatigue load limit is 34.5 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
- The N1MAS execution of 60-800-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 60-800-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 523000 g quoted mass includes the heavier cage.
- Open 60-800-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 60-800-N1MAS; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
Frequently asked questions
What are the dimensions of 60-800-N1MAS?
The SKF 60/800 N1MAS measures 800 mm bore × 1150 mm OD × 155 mm width (31.496 × 45.276 × 6.102 in), mass about 523000 g. It is open, with no shields or seals.
Why is there a slash in the designation 60/800 N1MAS?
The slash writes a bore that falls outside the two-digit code table: 60/800 means 800 mm bore. The site slug 60-800-N1MAS replaces the slash with a hyphen.
Which fits should I use for 60-800-N1MAS?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 1150 mm housing; reverse the interference if the outer ring rotates.
How heavy is 60-800-N1MAS?
Catalogue mass is 523000 g for 60/800 N1MAS; seal and cage executions of the same envelope differ by a few grams.
