How the 6013-2RS model number is decoded

6013-2RS 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 extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 13 by five gives the 65 mm bore; the 100 mm outside diameter and 18 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 65 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 6013-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Interference on a 65 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6013 with C3 clearance and re-check the residual value after mounting.
• Choosing the 60xx extra-light section saves radial space at 65 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6213 before committing to the smaller envelope.
• Contact seals add drag and heat: 6013-2RS runs slower and cooler-limited than the open 6013; 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 6013-2RS: 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.
• Measure the shaft, do not trust the drawing: a 65 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6013-2RS.
• 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 6013-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 4000 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 14000 r/min thermal reference speed. The single-seal catalogue number is 6013-RS1, used where one shaft side needs external relubrication.
• A one-seal execution 6013-RS1 exists for arrangements that lubricate through the open side; fitting 6013-2RS1 instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
• The 31.9/25 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.
