How the 6302-2RS model number is decoded

6302-2RS 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 medium 63xx section (diameter series 3 of ISO 15), its bore code 02 comes from the 10/12/15/17 mm exception table, giving a 15 mm bore; the 42 mm outside diameter and 13 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 15 mm shaft under normal load, catalogue practice seats it on a j5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. SKF's contact-seal catalogue number is 6302-2RSH (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Miniature bearings like 6302-2RS (15 mm bore) brinell under surprisingly small pressing force; use a fitting sleeve on the ring being mounted and never let the assembly load cross the balls.
• The 63xx medium section at 15 mm bore gains dynamic rating through larger rolling elements on a 42 mm OD; the penalty is mass and a lower limiting speed than the 6202 — do not specify it for speed-critical shafts.
• Contact seals add drag and heat: 6302-2RS runs slower and cooler-limited than the open 6302; 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 6302-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
• Do not quieten a noisy bearing by preloading it: the 6300-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
• Vibration during standstill brinells the raceways of a 15 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
• SKF catalogues the contact-sealed version as 6302-2RSH (older printings may read -2RS1); it is shipped pre-greased and its 12000 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 38000 r/min thermal reference speed. The single-seal catalogue number is 6302-RSH, used where one shaft side needs external relubrication.
• A one-seal execution 6302-RSH exists for arrangements that lubricate through the open side; fitting 6302-2RSH instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
• The 11.9/5.4 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.
