How the 6207-FAG model number is decoded

In the 6200-series (diameter series 2 of ISO 15) the last two digits encode the bore: 6207 carries bore code 07 = 35 mm. Outside diameter 72 mm and width 17 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 35 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

• A 35 mm shaft for 6207 should be finished to Ra ≤ 1.6 µm with square seating faces; at this bore a scored or oval journal shows up directly as running noise and early raceway damage.
• The 62xx light series is the default general-purpose section at 35 mm bore; before upgrading to a 6307 for extra capacity, confirm the housing accepts a 72 mm OD and 17 mm width — it is not a drop-in swap.
• The open 6207-FAG has no lubricant retention: grease escapes and contaminants migrate straight into the 35×72×17 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Storage matters for open bearings: 6207-FAG 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.
• A 35 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 housing bore for the 72 mm OD should be round within IT7; an oval bore pinches the outer ring of 6207-FAG and shows up later as two-point loaded raceway wear.
• The open 6207 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 rates 6207 at 15000 r/min mechanical limiting speed (thermal reference speed 11300 r/min) — electric-motor territory; prefer the open or 2Z execution (sealed 2RSR variants lose roughly a third of the thermal speed) and confirm grease life at the reference speed for continuous running.
• The 35 mm bore puts 6207 in Schaeffler's general-purpose industrial range; the standard cage and CN clearance cover most electric-motor and pump duty, and FAG's X-life generation of these sizes carries higher ratings than legacy HR 1 printings — check the current eKatalog listing before reordering.
• At 28 kN dynamic load rating (C) and 15.4 kN static (C0), 6207 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 291 g, 6207 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 35×72×17 mm envelope of 6207 gives a D/d ratio of 2.06 and 18.5 mm radial section height — a heavy FAG section for high-load, lower-speed duty; specifying it in a high-rpm motor generates excess heat and shortens grease life, so prefer a 62/63-series there.
• The 28/15.4 kN load ratings, mass 291 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 6207-C on the 35×72×17 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6207 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.
• For hot shafts above roughly 100 °C continuous, consult Schaeffler about seal material and grease options for the 2RSR execution of 6207; the standard NBR lip is the economical general-duty choice, not the high-temperature one.
• 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.
