How the 6024 model number is decoded

In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6024 carries bore code 24 = 120 mm. Outside diameter 180 mm and width 28 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 120 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

Selection pitfalls — read before you substitute

• Large bores like the 120 mm of 6024 demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
• The 60xx extra-light section at 120 mm bore uses a smaller 180 mm OD than a 6224; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
• The open 6024 has no lubricant retention: grease escapes and contaminants migrate straight into the 120×180×28 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Open bearings tolerate the highest speeds in the 6000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6024 units.
• A 120 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
• Shaft and housing fillets must clear the bearing chamfer so the 28 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
• The open 6024 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6024-2Z (shields) and 6024-2RSH (contact seals), not suffix-free 6024.
• The 88.4/80 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.
