How the 61932-FAG 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 Schaeffler HR 1 catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes 2Z (steel shields), 2RZ (non-contact rubber seals) and 2RSR (lip-contact rubber seals).

Typical equipment & failure modes

Common applications

  • robotics and automation joints
  • lay shafts and idler shafts
  • textile machinery
  • packaging machinery

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 at 160 mm bore (30.0 mm section height) cannot shrug off the misalignment a standard section tolerates; keep the housing bores round and aligned, or edge contact will spall the raceways early.
  • Storage matters for open bearings: 61932-FAG leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
  • 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.
  • Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 28 mm-wide ring of 61932-FAG drags the lip and overheats it.
  • Deep-groove ball bearings tolerate only minutes of misalignment; if the 220 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 61932-FAG.
  • The open 61932 has no integral sealing; in the Schaeffler HR 1 catalogue the protected variants carry suffixes 2Z (two steel shields), 2RZ (two non-contact rubber seals) and 2RSR (two lip-contact rubber seals). Do not confuse FAG's 2RZ with a contact seal — the RZ lip does not touch the inner ring, which is why its speed capability stays close to the open bearing.
  • FAG lists the mechanical limiting speed at 4050 r/min for 61932 (thermal reference speed 3450 r/min); the thermal reference speed is the binding figure for continuous duty — size the lubrication interval off the reference speed, not the mechanical limit.
  • The 160 mm bore places 61932 at the lower end of Schaeffler's large-size range; at these diameters the pressed steel cage is speed-limited and FAG commonly offers a machined brass cage (suffix M) as an option. Verify cage material and relubrication provision with the distributor, and do not extrapolate small-bore speed ratings to this size.
  • At 98 kN dynamic load rating (C) and 99 kN static (C0), 61932 is a heavy-load FAG bearing for industrial gearboxes and large conveyors; Schaeffler expects a machined brass cage (suffix M) at this rating for shock duty, and C0 must be checked against mounting or lifting loads.
  • At 2700 g (2.7 kg), 61932 needs mechanical handling for mounting; Schaeffler recommends induction heating the inner ring (max 120 °C) rather than pressing cold, and a lifting provision if the housing is pre-assembled.
  • The 160×220×28 mm envelope of 61932 gives a D/d ratio of 1.38 and only 30.0 mm radial section height — an ultra-thin section in the HR 1 range where shaft deflection and housing ovality load the ball-raceway contact directly; verify shaft stiffness (target deflection under 0.05 mm) before choosing it over a 62-series.
  • The 98/99 kN load ratings, mass 2700 g here are Schaeffler HR 1 Rolling Bearings (Jan 2020) catalogue figures for 61932-FAG on the 160×220×28 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 61932 in a rated drive. Where FAG has since released an X-life version of this size, its expanded C/C0 ratings supersede the HR 1 print values quoted here.
  • Mixing old and new FAG generations of the same designation in one arrangement is dimensionally acceptable, but where ratings matter — preloaded or matched sets — order both positions from the same generation and lot.
  • Schaeffler has moved many HR 1 sizes to the X-life generation with higher C/C0 ratings; the designation is unchanged, so a current eKatalog listing for 61932 may quote higher values than the HR 1 print figures on this page — the envelope is identical either way.

Frequently asked questions

What are the dimensions of a 61932-FAG bearing?

A 61932-FAG 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.

What internal clearance does 61932-FAG have?

Unless a clearance suffix says otherwise, 61932-FAG is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 61932 and verify the residual clearance after mounting.

How should 61932-FAG 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 is the FAG order number for an open 61932?

FAG lists the open 61932 under the bare designation 61932-FAG; protected versions use suffixes 2Z (steel shields), 2RZ (non-contact rubber seals) and 2RSR (lip-contact rubber seals) on the same 160 mm bore envelope.

Does FAG offer 61932 with C3 clearance?

FAG lists C3 internal clearance for most deep-groove sizes (suffix C3 follows the seal code); choose C3 for tight fits or hot shafts and stay with the standard CN clearance of 61932-FAG for normal duty.
