How the 16011 model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16011 carries bore code 11 = 55 mm. Outside diameter 90 mm and width 11 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 55 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. 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

• Interference on a 55 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 16011 with C3 clearance and re-check the residual value after mounting.
• Because the 160xx narrow section shares the 90 mm OD of the 6011 at 55 mm bore but is only 11 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
• The open 16011 has no lubricant retention: grease escapes and contaminants migrate straight into the 55×90×11 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Storage matters for open bearings: 16011 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
• Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 11 mm-wide ring of 16011 drags the lip and overheats it.
• Suffixes stack in a defined order — clearance follows the seal code, e.g. 16011-C3. No clearance suffix means normal CN clearance.
• The open 16011 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.
• At 10900 r/min mechanical limiting speed (thermal reference speed 6000 r/min), 16011 covers general-purpose motor and pump duty; keep grease fill at 25–35% of free volume and verify the housing can dissipate the frictional heat at the thermal reference speed.
• At 55 mm bore 16011 is in Schaeffler's upper general-purpose range; the pressed steel cage is standard but mid-section 63xx sizes at this bore can be ordered with a machined brass cage (suffix M) for shock or very-low-speed duty — confirm cage material with the Schaeffler channel if the application sees impact loads.
• At 19.3 kN dynamic load rating (C) and 16.3 kN static (C0), 16011 is a medium-load FAG bearing for most electric-motor and pump duty; check the static safety factor against C0 for preloaded or thrust-loaded arrangements.
• At 260 g, 16011 requires a soft-jaw vise or arbor press for mounting — never hammer it onto the shaft, and support the opposite ring to avoid brinelling the raceways.
• The 55×90×11 mm envelope of 16011 gives a D/d ratio of 1.64 and 17.5 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 19.3/16.3 kN load ratings, mass 260 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 16011 on the 55×90×11 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16011 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 16011: 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 16011; the standard NBR lip is the economical general-duty choice, not the high-temperature one.
