How the 61922-MA model number is decoded

In the 61900-series, the last two digits encode the bore: 61922 carries code 22 = 110 mm (code × 5). The envelope is 110×150×20 mm (4.331×5.906×0.787 in) with a 20.0 mm radial section height, C 43.6 kN, C0 45 kN and Pu 1.66 kN. The open 61922 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 7500 r/min, catalogue mass 1050 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The fatigue load limit is 1.66 kN; it feeds the equivalent-mean-load check, not the basic life calculation — do not substitute one for the other.
• Fillet radii must clear the 61922-MA chamfer so the 20 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
• The MA suffix on 61922-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 1050 g quoted mass includes the heavier cage.
• Open 61922-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 61922-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 110 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.
• Sealed SKF units are filled with a lithium-based grease for general service; food-grade, low-temperature and high-temperature fills are order options and are not field-interchangeable once the unit is sealed.
• Where two 61922 bearings share one shaft in a preloaded or matched arrangement, order both from the same production lot; catalogue figures describe a single bearing, not a matched set.
