How the 61822 model number is decoded
61822 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the extra-thin 618xx section (diameter series 8 of ISO 15), multiplying bore code 22 by five gives the 110 mm bore; the 140 mm outside diameter and 16 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 110 mm shaft under normal load, catalogue practice seats it on a m6 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. 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
- clutch and transmission assemblies
- robotics and automation joints
- lay shafts and idler shafts
- textile machinery
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- cage damage from operation beyond the limiting speed
- electrical pitting in VFD-driven motors without grounding protection
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.
- Only 15.0 mm of radial section separates bore and OD on the 618xx series at 110 mm: ring flex from clamping or an oval housing bore transfers straight into raceway stress, so seat roundness matters more here than on a 6222.
- The open 61822 has no lubricant retention: grease escapes and contaminants migrate straight into the 110×140×16 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 61822 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.
- Never mix components between two 61822 units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- Vibration during standstill brinells the raceways of a 110 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- The open 61822 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61822-2Z (shields) and 61822-2RSH (contact seals), not suffix-free 61822.
- The 28.1/26 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 61822 bearing?
A 61822 deep-groove ball bearing has a 110 mm bore, 140 mm outer diameter and 16 mm width (4.331 × 5.512 × 0.63 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
How does the 61822 bore code work?
The last two digits of 61822 are bore code 22, giving 22 × 5 = 110 mm bore. The 140 mm outside diameter and 16 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 61822 mean?
A bare 61822 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 61800 compare with other series at the same 110 mm bore?
618 is an extra-thin section: 140×16 mm, only 15.0 mm radial section at 110 mm bore, far smaller than a 6222, for space-limited layouts at the cost of load rating and misalignment tolerance.
What is the SKF designation and catalogue data for 61822?
In the SKF Rolling Bearings catalogue this size is listed as 61822 — the open (unsealed) execution, 110×140×16 mm per ISO 15. Quoted values: C 28.1 kN, C0 26 kN, Pu 1.25 kN, limiting speed 5600 r/min, mass 470 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61822.
