How the 6206-2RS model number is decoded

6206-2RS is closed by two contacting elastomer lips over a lifetime grease fill; the lips add friction, so the speed ceiling sits below the open execution. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 06 by five gives the 30 mm bore; the 62 mm outside diameter and 16 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 30 mm shaft under normal load, catalogue practice seats it on a k5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. SKF's contact-seal catalogue number is 6206-2RSH (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

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.
• Contact seals add drag and heat: 6206-2RS runs slower and cooler-limited than the open 6206; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
• Heat is the enemy of the sealed 6206-2RS: sustained running near the lip temperature limit hardens the rubber, after which grease escapes and dirt tracks in — watch the housing temperature in hot drives.
• A 30 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.
• 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.
• SKF catalogues the contact-sealed version as 6206-2RSH (older printings may read -2RS1); it is shipped pre-greased and its 7500 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 24000 r/min thermal reference speed. The single-seal catalogue number is 6206-RSH, used where one shaft side needs external relubrication.
• A one-seal execution 6206-RSH exists for arrangements that lubricate through the open side; fitting 6206-2RSH instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
• The 20.3/11.2 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
