Mounting, lubrication & life for 6206-FAG
Recommended fits & mounting
- Rotating inner ring on a 30 mm shaft: k5; housing bore H7 for normal stationary-load outer rings. Reverse the logic if the outer ring rotates.
- Fit by induction heating (max 120 °C) where practical — never drive the ring home through the rolling elements.
- Keep shaft and housing fillet radii below the bearing chamfer so the 16 mm-wide ring seats square on its shoulder.
Lubrication strategy
Open execution: the application supplies lubrication. Use the grease relubrication chart for this bearing — pitch diameter dm = 46 mm, so the speed factor at the 17,800 r/min limiting speed is 818,800 mm·r/min. Intervals shorten steeply as that factor rises.
Worked L10 life example (illustrative duty)
For ball bearings, L10h = (C/P)3 · 106 / (60·n). Taking an example radial equivalent load P = 3 kN at n = 1,500 r/min (a small belted motor duty — substitute the real equivalent load from the application calculation):
C = 22.0 kN → L10h ≈ 4,382 hours — a warning that this section is lightly rated for a 3 kN load; a heavier section at the same 30 mm bore is the usual fix
Choosing a section at the same 30 mm bore
| Series | Open execution | OD × width | C (kN) | Limiting speed (r/min) |
|---|---|---|---|---|
| 60xx | 6006-FAG | 55 × 13 | 14.5 | 20,100 |
| 62xx | 6206-FAG | 62 × 16 | 22.0 | 17,800 |
| 63xx | 6306-FAG | 72 × 19 | 32.0 | 15,100 |
| 64xx | 6406-FAG | 90 × 23 | 42.5 | 11,000 |
| 618xx | 61806-FAG | 42 × 7 | 4.5 | 24,500 |
| 619xx | 61906-FAG | 47 × 9 | 7.2 | 21,700 |
| 160xx | 16006 | 55 × 9 | 11.2 | 18,500 |
A larger section is not a drop-in swap — OD and width change — and same-envelope seal variants are compared on the 30×62×16 envelope page. Match meaning, not the size chart alone: see what the cross-reference levels mean.

How the 6206-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. 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 30 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
Common applications
- agricultural equipment
- fans and blowers
- electric motors
- centrifugal pumps
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- A 30 mm shaft for 6206 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.
- At 30 mm bore the 62xx light series is the workhorse section; its 62×16 mm envelope is what most motor and gearbox seats are machined for, so any alternative section must be checked against both this OD and this width, not the bore alone.
- Storage matters for open bearings: 6206-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.
- Open bearings tolerate the highest speeds in the 6200-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6206 units.
- Measure the shaft, do not trust the drawing: a 30 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6206-FAG.
- 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.
- The open 6206 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 6206 at 17800 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 186 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 186 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 6206-C 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.
- 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.
- 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 6206 may quote higher values than the HR 1 print figures on this page — the envelope is identical either way.
Frequently asked questions
What are the dimensions of a 6206-FAG bearing?
A 6206-FAG deep-groove ball bearing has a 30 mm bore, 62 mm outer diameter and 16 mm width (1.181 × 2.441 × 0.63 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields.
What internal clearance does 6206-FAG have?
Unless a clearance suffix says otherwise, 6206-FAG is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6206 and verify the residual clearance after mounting.
How should 6206-FAG be mounted?
Apply the mounting force to the ring being fitted: on a 30 mm shaft seat the press load must pass through the inner-ring face only. A fitting sleeve and an arbor press are normally sufficient at this size. Never strike the outer ring, the cage or the seals.
What is the FAG order number for an open 6206?
FAG lists the open 6206 under the bare designation 6206-C; protected versions use suffixes 2Z (steel shields), 2RZ (non-contact rubber seals) and 2RSR (lip-contact rubber seals) on the same 30 mm bore envelope.
Does FAG offer 6206 with C3 clearance?
FAG lists C3 internal clearance for most deep-groove sizes (suffix C3 follows the seal code); choose C3 for tight fits or hot shafts and stay with the standard CN clearance of 6206-C for normal duty.
