How the 61932-ZZ-NTN model number is decoded

61932-ZZ carries two non-contact sheet-steel shields that hold the factory grease in and keep coarse debris out; they do not seal against liquids. 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. NTN catalogue order number: 6932ZZ (suffix ZZ), two non-contact steel shields, mapped here from the industry-neutral -ZZ spelling.

Typical equipment & failure modes

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.
• ZZ shields are non-contact: 61932-ZZ-NTN blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 61932-2RS for that.
• Shielded 61932-ZZ-NTN units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
• 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-ZZ-NTN.
• 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-ZZ-NTN.
• NTN catalogues the shielded version as 6932ZZ — suffix ZZ, two non-contact steel shields. The industry-neutral page spelling is -ZZ; quote the NTN order number when buying through an NTN channel.
• The 160 mm bore places 61932 at the lower end of NTN's large-size range; at these diameters the pressed-steel cage is speed-limited and NTN commonly supplies a machined brass cage (suffix M) as an option. Verify cage material and relubrication interval with the NTN distributor, and do not extrapolate small-bore speed ratings to this size.
• NTN lists the grease limiting speed at 2800 r/min for 61932; this is a large or heavy-section size where centrifugal force and cage inertia cap the speed — for higher shaft speeds either step to a smaller bearing on the same bore or consult NTN for an oil-lubricated, machined-cage variant.
• At 96.5 kN dynamic load rating (C) and 96 kN static (C0), 4.65 kN fatigue load limit Cu, 61932 is a heavy-load bearing for industrial gearboxes and large conveyors; NTN expects a machined brass cage (suffix M) at this rating for shock duty, and the static C0 must be checked against any mounting or lifting loads.
• At 2610 g (2.6 kg), 61932 needs mechanical handling for mounting; NTN recommends induction heating the inner ring (max 120 °C) rather than pressing cold, and a lifting eye 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 — this is an ultra-thin section where shaft deflection and housing ovality directly load the ball-raceway contact; verify shaft stiffness (target deflection under 0.05 mm) before specifying it over a 62-series.
• The 96.5/96 kN load ratings, 4.65 kN fatigue load limit Cu NTN lists the grease limiting speed at 2800 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 2610 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6932ZZ 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.
• Standard catalogue stock of 61932 is the general-purpose execution; for low-noise motor duty NTN offers low-torque seal and special-grease variants in this size class, which are separate order numbers.
• Factory-fill grease in NTN sealed units is a general-duty lithium-soap grease; food-grade, low-temperature and high-temperature fills are request options at order time, because LLU/LLB units are not meant to be opened and re-greased in the field.
