How the 6032-2RS-NTN model number is decoded

6032-2RS is closed by two contacting elastomer lips over a lifetime grease fill; the lips add friction, so the speed ceiling sits below the open execution. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 32 by five gives the 160 mm bore; the 240 mm outside diameter and 38 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's contact-seal catalogue number is 6032LLU (suffix LLU, or LLH low-torque variant), mapped here from the industry-neutral -2RS spelling; the contacting lip lowers the speed ceiling versus the open bearing.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Large bores like the 160 mm of 6032-2RS-NTN demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
• The 60xx extra-light section at 160 mm bore uses a smaller 240 mm OD than a 6232; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
• Contact seals add drag and heat: 6032-2RS-NTN runs slower and cooler-limited than the open 6032; 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 6032-2RS-NTN in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
• Vibration during standstill brinells the raceways of a 160 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
• The housing bore for the 240 mm OD should be round within IT7; an oval bore pinches the outer ring of 6032-2RS-NTN and shows up later as two-point loaded raceway wear.
• NTN catalogues the contact-sealed version as 6032LLU (suffix LLU), mapped here from the industry-neutral -2RS spelling; it is greased for life and the contacting lip lowers the speed ceiling versus the open bearing.
• The 160 mm bore places 6032 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 1600 r/min for 6032; 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 158 kN dynamic load rating (C) and 144 kN static (C0), 7.3 kN fatigue load limit Cu, 6032 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 5050 g (5.0 kg), 6032 is a heavy bearing that requires a crane or hoist for handling; induction-heat the inner ring (max 120 °C) and use a mechanical puller for removal — never apply heat directly to the balls or cage.
• The 160×240×38 mm envelope of 6032 gives a D/d ratio of 1.50 and 40.0 mm radial section height — this thin section saves space but is sensitive to misalignment and shock; confirm the housing stays round within IT7 and the shaft does not deflect past the raceway contact angle under load.
• The 158/144 kN load ratings, 7.3 kN fatigue load limit Cu NTN lists the grease limiting speed at 1600 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 5050 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6032LLU on the 160×240×38 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6032 in a rated drive.
• Order the C3 internal-clearance version (6032 with C3 after the seal code) when the shaft fit is tight or the shaft-to-housing temperature gradient exceeds roughly 10 °C — the residual clearance after mounting, not the catalogue CN figure, decides service life.
• Two NTN bearings of the same designation from different production lots can carry minor internal-geometry revisions; for paired or preloaded arrangements on one shaft, order a single lot through the NTN distributor.
