How the 61932 model number is decoded
61932 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the thin 619xx section (diameter series 9 of ISO 15), multiplying bore code 32 by five gives the 160 mm bore; the 220 mm outside diameter and 28 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 160 mm shaft under normal load, catalogue practice seats it on a m6 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
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
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- brinelling from static overload or hammering during mounting
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.
- The open 61932 has no lubricant retention: grease escapes and contaminants migrate straight into the 160×220×28 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 61900-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 61932 units.
- Do not quieten a noisy bearing by preloading it: the 61900-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
- Measure the shaft, do not trust the drawing: a 160 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 61932.
- The open 61932 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 61932-2Z (shields) and 61932-2RSH (contact seals), not suffix-free 61932.
- The 92.3/98 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.
Frequently asked questions
What are the dimensions of a 61932 bearing?
A 61932 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 an open bearing with no seals or shields.
How should 61932 be mounted?
Apply the mounting force to the ring being fitted: on a 160 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 61932 need?
The open 61932 is lubricated by the application; a NLGI 2 lithium-soap grease filled to roughly 25–35% of the free volume is the common choice, with a defined relubrication interval.
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 is the SKF designation and catalogue data for 61932?
In the SKF Rolling Bearings catalogue this size is listed as 61932 — the open (unsealed) execution, 160×220×28 mm per ISO 15. Quoted values: C 92.3 kN, C0 98 kN, Pu 3.05 kN, limiting speed 3800 r/min, mass 2700 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61932.
