How the 61802 model number is decoded

61802 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), its bore code 02 comes from the 10/12/15/17 mm exception table, giving a 15 mm bore; the 24 mm outside diameter and 5 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 15 mm shaft under normal load, catalogue practice seats it on a j5 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

Selection pitfalls — read before you substitute

• Codes 00–03 are the exception series: 61802 takes its 15 mm bore from the 10/12/15/17 mm table, so two designations only a few millimetres apart can read alike on paper — order by measured shaft size, not by code arithmetic.
• Only 4.5 mm of radial section separates bore and OD on the 618xx series at 15 mm: ring flex from clamping or an oval housing bore transfers straight into raceway stress, so seat roundness matters more here than on a 6202.
• The open 61802 has no lubricant retention: grease escapes and contaminants migrate straight into the 15×24×5 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Open bearings tolerate the highest speeds in the 61800-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 61802 units.
• Vibration during standstill brinells the raceways of a 15 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
• Measure the shaft, do not trust the drawing: a 15 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 61802.
• The open 61802 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61802-2Z (shields) and 61802-2RSH (contact seals), not suffix-free 61802.
• The 1.9/1.1 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.
