How the 6226-2RS model number is decoded

6226-2RS 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 26 by five gives the 130 mm bore; the 230 mm outside diameter and 40 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 130 mm shaft under normal load, catalogue practice seats it on a m6 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. SKF's contact-seal catalogue number is 6226-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount this 130 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
• At 130 mm bore the 62xx light series is the workhorse section; its 230×40 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.
• Heat is the enemy of the sealed 6226-2RS: 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.
• Never wash a sealed 6226-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
• Shaft and housing fillets must clear the bearing chamfer so the 40 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
• Measure the shaft, do not trust the drawing: a 130 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6226-2RS.
• SKF catalogues the contact-sealed version as 6226-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 1800 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 5600 r/min thermal reference speed. The single-seal catalogue number is 6226-RS1, used where one shaft side needs external relubrication.
• A one-seal execution 6226-RS1 exists for arrangements that lubricate through the open side; fitting 6226-2RS1 instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
• The 156/132 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.
