How the 6015-2RS model number is decoded

In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6015 carries bore code 15 = 75 mm. Outside diameter 115 mm and width 20 mm come from the ISO 15 boundary-dimensions general plan. Suffix -2RS denotes two contact-type elastomer seals over a lifetime grease fill; the sealing lips add drag compared with open or shielded versions. For normal-load mounting with a rotating inner ring on a 75 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's contact-seal catalogue number is 6015-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Temperature rise and interference fits consume internal clearance on this 75 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 6015 with C3 for those conditions.
• Choosing the 60xx extra-light section saves radial space at 75 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 6215 before committing to the smaller envelope.
• Contact seals add drag and heat: 6015-2RS runs slower and cooler-limited than the open 6015; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
• Never wash a sealed 6015-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
• Never mix components between two 6015-2RS units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• The housing bore for the 115 mm OD should be round within IT7; an oval bore pinches the outer ring of 6015-2RS and shows up later as two-point loaded raceway wear.
• SKF catalogues the contact-sealed version as 6015-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 3400 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 12000 r/min thermal reference speed. The single-seal catalogue number is 6015-RS1, used where one shaft side needs external relubrication.
• A one-seal execution 6015-RS1 exists for arrangements that lubricate through the open side; fitting 6015-2RS1 instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
• The 41.6/33.5 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.
