How the 60-750-MA model number is decoded
In the large-bore 6000-series, the bore is written directly after the slash as 750 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 750×1090×150 mm (29.528×42.913×5.906 in) with a 170.0 mm radial section height, C 995 kN, C0 2360 kN and Pu 33.5 kN. The open 60/750 MA carries no shields or seals and relies on application lubrication and external sealing. The MA suffix identifies the machined brass cage execution, a separate order number from the pressed-steel version. Limiting speed 800 r/min, catalogue mass 485000 g.
Typical equipment & failure modes
Common applications
- hoists and winches
- industrial fans and blowers
- mill and kiln auxiliaries
- pulp and paper machinery
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
- Assign interference to the rotating ring: on a conventional shaft-mounted 750 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 60-750-MA home through the outer ring or balls brinells the raceways.
- The MA suffix on 60-750-MA 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 485000 g quoted mass includes the heavier cage.
- Open 60-750-MA 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 60-750-MA; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Mount by heating the inner ring (max 120 °C) — driving 60-750-MA home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of 60-750-MA?
The SKF 60/750 MA measures 750 mm bore × 1090 mm OD × 150 mm width (29.528 × 42.913 × 5.906 in), mass about 485000 g. It is open, with no shields or seals.
Why is there a slash in the designation 60/750 MA?
The slash writes a bore that falls outside the two-digit code table: 60/750 means 750 mm bore. The site slug 60-750-MA replaces the slash with a hyphen.
What is the difference between 60-750-MA and a same-bore 62-series bearing?
Section height differs: 60-750-MA has a 170 mm radial section and C 995 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 60-750-MA?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 1090 mm housing; reverse the interference if the outer ring rotates.
