How the 619-710-MA model number is decoded
In the large-bore 61900-series, the bore is written directly after the slash as 710 mm (large thin-section bores use the slash spelling instead of the two-digit code). The envelope is 710×950×106 mm (27.953×37.402×4.173 in) with a 120.0 mm radial section height, C 663 kN, C0 1500 kN and Pu 22 kN. The open 619/710 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 900 r/min, catalogue mass 220000 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.
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
- brinelling from static overload or hammer blows during mounting
- false brinelling from vibration while the shaft stands idle
Selection pitfalls — read before you substitute
- Deep-groove geometry tolerates only minutes of misalignment; if the 950 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 619-710-MA.
- At 710 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.
- The MA suffix on 619-710-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 220000 g quoted mass includes the heavier cage.
- Open 619-710-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 619-710-MA; run-to-failure on open deep-groove bearings is the dominant early-failure cause.
- Deep-groove geometry tolerates only minutes of misalignment; if the 950 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming 619-710-MA.
Frequently asked questions
What are the dimensions of 619-710-MA?
The SKF 619/710 MA measures 710 mm bore × 950 mm OD × 106 mm width (27.953 × 37.402 × 4.173 in), mass about 220000 g. It is open, with no shields or seals.
Why is there a slash in the designation 619/710 MA?
The slash writes a bore that falls outside the two-digit code table: 619/710 means 710 mm bore. The site slug 619-710-MA replaces the slash with a hyphen.
What is the difference between 619-710-MA and a same-bore 62-series bearing?
Section height differs: 619-710-MA has a 120 mm radial section and C 663 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
Which fits should I use for 619-710-MA?
With a rotating inner ring use roughly m6 on the shaft and H7 in the 950 mm housing; reverse the interference if the outer ring rotates.
