How the 61922 model number is decoded
In the 61900-series (diameter series 9 of ISO 15) the last two digits encode the bore: 61922 carries bore code 22 = 110 mm. Outside diameter 150 mm and width 20 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 110 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- lay shafts and idler shafts
- textile machinery
- packaging machinery
- space-constrained gearboxes
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Mount this 110 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 619xx thin section at 110 mm bore (20.0 mm section height) cannot shrug off the misalignment a standard section tolerates; keep the housing bores round and aligned, or edge contact will spall the raceways early.
- The open 61922 has no lubricant retention: grease escapes and contaminants migrate straight into the 110×150×20 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 61922 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- Measure the shaft, do not trust the drawing: a 110 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 61922.
- Never mix components between two 61922 units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- The open 61922 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61922-2Z (shields) and 61922-2RSH (contact seals), not suffix-free 61922.
- The 43.6/45 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 61922 bearing?
A 61922 deep-groove ball bearing has a 110 mm bore, 150 mm outer diameter and 20 mm width (4.331 × 5.906 × 0.787 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What internal clearance does 61922 have?
Unless a clearance suffix says otherwise, 61922 is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 61922 and verify the residual clearance after mounting.
How should 61922 be mounted?
Apply the mounting force to the ring being fitted: on a 110 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 61922 need?
The open 61922 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
What is the SKF designation and catalogue data for 61922?
In the SKF Rolling Bearings catalogue this size is listed as 61922 — the open (unsealed) execution, 110×150×20 mm per ISO 15. Quoted values: C 43.6 kN, C0 45 kN, Pu 1.66 kN, limiting speed 5600 r/min, mass 900 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61922.
