How the 61802-2RS model number is decoded

In the 61800-series (diameter series 8 of ISO 15) the last two digits encode the bore: 61802 carries bore code 02 = 15 mm. Codes 00–03 follow the 10/12/15/17 mm exception table rather than code × 5. Outside diameter 24 mm and width 5 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 15 mm shaft, typical catalogue practice is a j5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's contact-seal catalogue number is 61802-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Bore codes 00–03 use the exception table: 61802 fits a 15 mm shaft — the code × 5 mnemonic does not apply below code 04 (it would imply 0 mm for code 00).
• The 618xx thin section at 15 mm bore has only a 4.5 mm radial section height: it saves space but is highly sensitive to misalignment, shaft deflection and shock loads — verify shaft stiffness before choosing it over a 6202.
• Contact seals add drag and heat: 61802-2RS runs slower and cooler-limited than the open 61802; 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 61802-2RS: 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 mix components between two 61802-2RS units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• Deep-groove ball bearings tolerate only minutes of misalignment; if the 24 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 61802-2RS.
• SKF catalogues the contact-sealed version as 61802-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 17000 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 60000 r/min thermal reference speed.
• The 1.9/1.1 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.
