How the 6206-ZZ-FAG model number is decoded

In the 6200-series (diameter series 2 of ISO 15) the last two digits encode the bore: 6206 carries bore code 06 = 30 mm. Outside diameter 62 mm and width 16 mm come from the ISO 15 boundary-dimensions general plan. Suffix -ZZ denotes two non-contact metallic shields; they retain grease and block coarse debris but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 30 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. Schaeffler HR 1 catalogue order number: 6206-C-2Z (FAG suffix 2Z), two non-contact steel shields, mapped here from the industry-neutral -ZZ spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• At a 30 mm bore, a shaft-seat burr or an overtight setscrew can score the thin inner ring of 6206-ZZ-FAG; check shaft finish and runout (target Ra ≤ 1.6 µm) before pressing it home.
• The 62xx light series is the default general-purpose section at 30 mm bore; before upgrading to a 6306 for extra capacity, confirm the housing accepts a 62 mm OD and 16 mm width — it is not a drop-in swap.
• ZZ shields are non-contact: 6206-ZZ-FAG blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6206-2RS for that.
• Shielded 6206-ZZ-FAG units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
• Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
• Shaft and housing fillets must clear the bearing chamfer so the 16 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
• Schaeffler HR 1 lists the shielded version as 6206-C-2Z — FAG suffix 2Z, two non-contact steel shields. The industry-neutral page spelling is -ZZ; quote the FAG order number when buying through a Schaeffler channel.
• FAG rates 6206 at 15100 r/min mechanical limiting speed (thermal reference speed 13400 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 30 mm bore puts 6206 in Schaeffler's light industrial range; the standard cage and CN clearance cover most fractional-horsepower motor and small-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 22 kN dynamic load rating (C) and 11.3 kN static (C0), 6206 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 193 g, 6206 is light enough for hand assembly but should be pressed on with a fitting sleeve against the inner ring; do not strike the outer ring or cage with a hammer.
• The 30×62×16 mm envelope of 6206 gives a D/d ratio of 2.07 and 16.0 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 22/11.3 kN load ratings, mass 193 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 6206-C-2Z on the 30×62×16 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6206 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 6206; the standard NBR lip is the economical general-duty choice, not the high-temperature one.
• FAG standard tolerance for this size is P0 (PN); P6/P5 precision executions exist for spindle-adjacent duty but carry different order numbers in the Schaeffler system — they are not a selectable sorting of standard stock.
