How the 61832-2RS model number is decoded
In the 61800-series (ISO 15 diameter series 8) the last two digits encode the bore: 61832 carries bore code 32 = 160 mm. Outside diameter 200 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 160 mm shaft, typical catalogue practice is a m6 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude.
Typical equipment & failure modes
Common applications
- textile machinery
- packaging machinery
- space-constrained gearboxes
- clutch and transmission assemblies
Known failure patterns
- seal-lip hardening and loss of pre-grease in sustained high-temperature service
- grease-life expiry in the sealed-for-life cavity (no relubrication path)
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- Mount this 160 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 618xx thin section at 160 mm bore has only a 20.0 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 6232.
- Contact seals add drag and heat: 61832-2RS runs slower and cooler-limited than the open 61832; 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 61832-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 61832-C3. No clearance suffix means normal CN clearance.
- NSK catalogues the contact-sealed version as 6832DDU (suffix DDU), the NSK equivalent of the industry-neutral -2RS spelling on this page; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing.
- The 53/61 kN ratings, mass 1230 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6832DDU; this seal/size combination has no counterpart in the SKF 17000 extract used elsewhere on this site, so the page rests on a single manufacturer source — internal geometry and ratings legitimately differ between brands, so re-verify before substituting in a rated drive.
Frequently asked questions
What are the dimensions of a 61832-2RS bearing?
A 61832-2RS deep-groove ball bearing has a 160 mm bore, 200 mm outer diameter and 20 mm width (6.299 × 7.874 × 0.787 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
How does the 61832 bore code work?
The last two digits of 61832 are bore code 32, giving 32 × 5 = 160 mm bore. The 200 mm outside diameter and 20 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the 2RS suffix on 61832-2RS mean?
2RS means two contact elastomer seals, one each side, usually over a lifetime grease fill. Sealing against dust and moisture is better than ZZ shields, but the lip drag lowers the speed and temperature ceiling.
How does the 61800 compare with other series at the same 160 mm bore?
618 is an extra-thin section: 200×20 mm, only 20.0 mm radial section at 160 mm bore, far smaller than a 6232, for space-limited layouts at the cost of load rating and misalignment tolerance.
What is the NSK designation and catalogue data for 61832-2RS?
In the NSK Rolling Bearings catalogue (E1103 Part C) this size is listed as 6832DDU — two contacting rubber seals over a lifetime grease fill (NSK suffix DDU), 160×200×20 mm per ISO 15. Quoted values: C 53 kN, C0 61 kN, mass 1230 g. The industry-neutral page spelling 61832-2RS follows the seal-suffix convention used across this site, not NSK order-number spelling. Reference and limiting speeds are not tabulated in the E1103 dimension tables used here; consult NSK speed tables before high-speed service.
