How the 6030 model number is decoded

In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6030 carries bore code 30 = 150 mm. Outside diameter 225 mm and width 35 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 150 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 150 mm of 6030 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 150 mm bore uses a smaller 225 mm OD than a 6230; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
• The open 6030 has no lubricant retention: grease escapes and contaminants migrate straight into the 150×225×35 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 6030 units.
• Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
• A 150 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.
• The open 6030 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6030-2Z (shields) and 6030-2RSH (contact seals), not suffix-free 6030.
• The 125/125 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.
