How the 6030-FAG model number is decoded

6030 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 30 by five gives the 150 mm bore; the 225 mm outside diameter and 35 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 150 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 Schaeffler HR 1 catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes 2Z (steel shields), 2RZ (non-contact rubber seals) and 2RSR (lip-contact rubber seals).

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Large bores like the 150 mm of 6030-FAG 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.
• Choosing the 60xx extra-light section saves radial space at 150 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6230 before committing to the smaller envelope.
• The open 6030-FAG 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.
• Measure the shaft, do not trust the drawing: a 150 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6030-FAG.
• Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 35 mm-wide ring of 6030-FAG drags the lip and overheats it.
• The open 6030 has no integral sealing; in the Schaeffler HR 1 catalogue the protected variants carry suffixes 2Z (two steel shields), 2RZ (two non-contact rubber seals) and 2RSR (two lip-contact rubber seals). Do not confuse FAG's 2RZ with a contact seal — the RZ lip does not touch the inner ring, which is why its speed capability stays close to the open bearing.
• FAG lists the mechanical limiting speed at 3950 r/min for 6030 (thermal reference speed 3850 r/min); the thermal reference speed is the binding figure for continuous duty — size the lubrication interval off the reference speed, not the mechanical limit.
• The 150 mm bore places 6030 at the lower end of Schaeffler's large-size range; at these diameters the pressed steel cage is speed-limited and FAG commonly offers a machined brass cage (suffix M) as an option. Verify cage material and relubrication provision with the distributor, and do not extrapolate small-bore speed ratings to this size.
• At 131 kN dynamic load rating (C) and 124 kN static (C0), 6030 is a heavy-load FAG bearing for industrial gearboxes and large conveyors; Schaeffler expects a machined brass cage (suffix M) at this rating for shock duty, and C0 must be checked against mounting or lifting loads.
• At 4260 g (4.3 kg), 6030 needs mechanical handling for mounting; Schaeffler recommends induction heating the inner ring (max 120 °C) rather than pressing cold, and a lifting provision if the housing is pre-assembled.
• The 150×225×35 mm envelope of 6030 gives a D/d ratio of 1.50 and 37.5 mm radial section height — a thin FAG section that saves space but is sensitive to misalignment and shock; keep the housing round within IT7 and the shaft deflection below the raceway contact envelope.
• The 131/124 kN load ratings, mass 4260 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 6030-FAG on the 150×225×35 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6030 in a rated drive. Where FAG has since released an X-life version of this size, its expanded C/C0 ratings supersede the HR 1 print values quoted here.
• Schaeffler's medias/eKatalog is the live source for the current execution of 6030: cage material, seal lip design and ratings can be revised between catalogue generations without any designation change.
• For hot shafts above roughly 100 °C continuous, consult Schaeffler about seal material and grease options for the 2RSR execution of 6030; the standard NBR lip is the economical general-duty choice, not the high-temperature one.
