How the 16040 model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16040 carries bore code 40 = 200 mm. Outside diameter 310 mm and width 34 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 200 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 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 200 mm of 16040 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 160xx narrow section at 200 mm bore shares the 310 mm outside diameter of the 6040 but is only 34 mm wide; a 6040 in a 34 mm-wide seat is loose axially and the reverse swap will not fit — match width as well as bore and outside diameter.
• The open 16040 has no lubricant retention: grease escapes and contaminants migrate straight into the 200×310×34 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Open bearings tolerate the highest speeds in the 16000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 16040 units.
• Vibration during standstill brinells the raceways of a 200 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
• Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 16000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
• The open 16040 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 2850 r/min for 16040 (thermal reference speed 2470 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 200 mm bore places 16040 in 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.
• FAG rates 16040 at 186 kN dynamic (C) and 202 kN static (C0); this is an extreme-load rating at the top of the HR 1 single-row deep-groove range, where mounting, shaft stiffness and housing alignment dominate achievable life — request a Schaeffler application review rather than relying on catalogue L10 alone.
• At 8970 g (9.0 kg), 16040 is a heavy FAG bearing that requires a crane or hoist for handling; induction-heat the inner ring (max 120 °C) and use a mechanical puller for removal — never apply heat directly to the balls or cage.
• The 200×310×34 mm envelope of 16040 gives a D/d ratio of 1.55 and 55.0 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 186/202 kN load ratings, mass 8970 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 16040 on the 200×310×34 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16040 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 has moved many HR 1 sizes to the X-life generation with higher C/C0 ratings; the designation is unchanged, so a current eKatalog listing for 16040 may quote higher values than the HR 1 print figures on this page — the envelope is identical either way.
• For hot shafts above roughly 100 °C continuous, consult Schaeffler about seal material and grease options for the 2RSR execution of 16040; the standard NBR lip is the economical general-duty choice, not the high-temperature one.
