How the 6030-2RS-FAG model number is decoded

6030-2RS is closed by two contacting elastomer lips over a lifetime grease fill; the lips add friction, so the speed ceiling sits below the open execution. 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. Schaeffler HR 1 catalogues the lip-contact sealed version as 6030-2RSR (FAG suffix 2RSR), mapped here from the industry-neutral -2RS spelling; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At 150 mm bore the ring mass is significant: heat 6030 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
• 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.
• Contact seals add drag and heat: 6030-2RS-FAG runs slower and cooler-limited than the open 6030; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
• Heat is the enemy of the sealed 6030-2RS: sustained running near the lip temperature limit hardens the rubber, after which grease escapes and dirt tracks in — watch the housing temperature in hot drives.
• Never mix components between two 6030-2RS-FAG units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• Deep-groove ball bearings tolerate only minutes of misalignment; if the 225 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6030-2RS-FAG.
• Schaeffler HR 1 lists the lip-contact sealed version as 6030-2RSR (FAG suffix 2RSR), mapped here from the industry-neutral -2RS spelling; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing. FAG's RSR lip material is NBR as standard — above roughly 100 °C continuous, consult Schaeffler for higher-temperature seal options.
• FAG lists the mechanical limiting speed at only 1540 r/min for 6030; this is a heavy-section size where cage inertia and centrifugal force cap rotation — do not run this size in a high-speed position, step to a smaller bearing on the same bore instead.
• 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 4380 g (4.4 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 4380 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 6030-2RSR 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.
• Mixing old and new FAG generations of the same designation in one arrangement is dimensionally acceptable, but where ratings matter — preloaded or matched sets — order both positions from the same generation and lot.
• 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.
