How the 619-600-MA model number is decoded
In the large-bore 61900-series, the bore is written directly after the slash as 600 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 600×800×90 mm (23.622×31.496×3.543 in) with a 100.0 mm radial section height, C 585 kN, C0 1220 kN and Pu 19.6 kN. The open 619/600 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 1100 r/min, catalogue mass 125000 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.
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
- fretting corrosion on a creeping shaft or housing seat
- cage damage from running beyond the limiting speed
Selection pitfalls — read before you substitute
- At 600 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 619-600-MA to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- The MA suffix on 619-600-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 125000 g quoted mass includes the heavier cage.
- Open 619-600-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 619-600-MA; 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 600 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 619-600-MA?
The SKF 619/600 MA measures 600 mm bore × 800 mm OD × 90 mm width (23.622 × 31.496 × 3.543 in), mass about 125000 g. It is open, with no shields or seals.
Why is there a slash in the designation 619/600 MA?
The slash writes a bore that falls outside the two-digit code table: 619/600 means 600 mm bore. The site slug 619-600-MA replaces the slash with a hyphen.
How heavy is 619-600-MA?
Catalogue mass is 125000 g for 619/600 MA; seal and cage executions of the same envelope differ by a few grams.
What load can 619-600-MA take?
Catalogue values for 619/600 MA: dynamic C 585 kN, static C0 1220 kN, fatigue limit Pu 19.6 kN. Use C in life calculation and C0 for static checks at 600 mm bore.
