How the 61932-2RS model number is decoded
In the 61900-series (ISO 15 diameter series 9) the last two digits encode the bore: 61932 carries bore code 32 = 160 mm. Outside diameter 220 mm and width 28 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
- space-constrained gearboxes
- clutch and transmission assemblies
- robotics and automation joints
- lay shafts and idler shafts
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)
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
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 619xx thin section (30.0 mm section height at 160 mm bore) trades load capacity for compactness; stiff, accurately aligned seats are essential or edge loading will spall the raceway early.
- Contact seals add drag and heat: 61932-2RS runs slower and cooler-limited than the open 61932; 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 61932-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- A 160 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
- NSK catalogues the contact-sealed version as 6932DDU (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 95.5/96 kN ratings, mass 2710 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6932DDU; 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 61932-2RS bearing?
A 61932-2RS deep-groove ball bearing has a 160 mm bore, 220 mm outer diameter and 28 mm width (6.299 × 8.661 × 1.102 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
How does the 61932 bore code work?
The last two digits of 61932 are bore code 32, giving 32 × 5 = 160 mm bore. The 220 mm outside diameter and 28 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the 2RS suffix on 61932-2RS 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 61900 compare with other series at the same 160 mm bore?
619 is a thin section one step above 618: 220×28 mm with a 30.0 mm radial section at 160 mm bore; a 6232 on the same bore is substantially larger and more heavily rated.
What is the NSK designation and catalogue data for 61932-2RS?
In the NSK Rolling Bearings catalogue (E1103 Part C) this size is listed as 6932DDU — two contacting rubber seals over a lifetime grease fill (NSK suffix DDU), 160×220×28 mm per ISO 15. Quoted values: C 95.5 kN, C0 96 kN, mass 2710 g. The industry-neutral page spelling 61932-2RS 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.
