How the 61822-RSR model number is decoded

In the 61800-series (diameter series 8 of ISO 15) the last two digits encode the bore: 61822 carries bore code 22 = 110 mm. Outside diameter 140 mm and width 16 mm come from the ISO 15 boundary-dimensions general plan. Suffix -RSR denotes two low-friction non-contact elastomer seals; they keep coarse debris out with minimal drag but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 110 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's low-friction seal suffix is 2RSL/2RZ (this page's industry-neutral spelling is -RSR); catalogue number 61822-2RZ.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Large bores like the 110 mm of 61822-RSR demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
• The 618xx thin section at 110 mm bore has only a 15.0 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 6222.
• RSR low-friction seals on 61822-RSR run faster than contact-seal 61822-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 61822-2RS instead.
• The low-drag lip of 61822-RSR barely touches the inner ring; after long shelf storage the grease can separate, so rotate the rings by hand and confirm smooth, silent running before fitting.
• Do not quieten a noisy bearing by preloading it: the 61800-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
• 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 low-friction seal as 61822-2RZ (suffix -2RSL or -2RZ): a non-contact elastomer lip that runs near the open 4500 r/min limiting speed, closer to the open bearing's 9500 r/min reference than the contact-seal version. It keeps coarse debris out without the drag of a contact seal, but is not liquid-tight — use 2RSH for wet or fine-dust positions.
• The 28.1/26 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.
