How the 16036-NTN model number is decoded

16036 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. Within the narrow 160xx section of the ISO 15 general plan, multiplying bore code 36 by five gives the 180 mm bore; the 280 mm outside diameter and 31 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 180 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 NTN catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes ZZ (shields), LLB/LLF (non-contact seals), LLH (low-torque contact seal) and LLU (contact seal).

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Mount this 180 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.
• Because the 160xx narrow section shares the 280 mm OD of the 6036 at 180 mm bore but is only 31 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
• The open 16036-NTN has no lubricant retention: grease escapes and contaminants migrate straight into the 180×280×31 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Storage matters for open bearings: 16036-NTN 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.
• Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 16000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
• Do not quieten a noisy bearing by preloading it: the 16000-series is a deep-groove design, not angular-contact; axial preload raises temperature and shortens grease life.
• The open 16036 has no integral sealing; in the NTN 2203 catalogue the protected variants carry suffixes ZZ (non-contact steel shields), LLB/LLF (non-contact rubber seals), LLU (contact rubber seals) and LLH (a low-torque contact seal with higher speed capability than LLU). A JR or JRX suffix (printed for some thin-section sizes) denotes a pressed-steel cage, not a seal.
• The 180 mm bore places 16036 in 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 2300 r/min for 16036; 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 129 kN dynamic load rating (C) and 134 kN static (C0), 5.85 kN fatigue load limit Cu, 16036 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 6490 g (6.5 kg), 16036 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 180×280×31 mm envelope of 16036 gives a D/d ratio of 1.56 and 50.0 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 129/134 kN load ratings, 5.85 kN fatigue load limit Cu NTN lists the grease limiting speed at 2300 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 6490 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16036 on the 180×280×31 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16036 in a rated drive.
• 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.
• Standard catalogue stock of 16036 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.
