How the 16002-NTN model number is decoded

In the 16000-series (the narrow extra-light section of ISO 15) the last two digits encode the bore: 16002 carries bore code 15 = 15 mm. Outside diameter 32 mm and width 8 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. For normal-load mounting with a rotating inner ring on a 15 mm shaft, typical catalogue practice is a j5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. 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

• At 15 mm bore, induction heating to roughly 80–100 °C is the clean mounting method; never exceed 120 °C, and hold 16002 against the shaft shoulder while it cools so the ring cannot creep back.
• Because the 160xx narrow section shares the 32 mm OD of the 6015 at 15 mm bore but is only 8 mm wide, a housing machined for the wider bearing needs a spacer or relocated circlip — never assume width interchangeability.
• Storage matters for open bearings: 16002-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.
• Open bearings tolerate the highest speeds in the 16000-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 16002 units.
• Suffixes stack in a defined order — clearance follows the seal code, e.g. 16002-NTN-C3. No clearance suffix means normal CN clearance.
• Never mix components between two 16002-NTN units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• The open 16002 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.
• At 15 mm bore the 16002 sits in NTN's small-bore range; ABEC-1/P0 runout is standard, and the pressed-steel cage is adequate up to the grease limiting speed — for higher accuracy (spindles, instruments) ask NTN for a P6 or P5 tolerance-class listing before relying on catalogue P0 figures.
• NTN rates 16002 at 22000 r/min grease limiting speed — this is a high-speed electric-motor range; keep the grease fill at 20–30% of the free bearing volume and avoid mixing grease thickener types if regreasing through the housing.
• NTN rates 16002 at 6.2 kN dynamic (C) and 2.84 kN static (C0), 0.22 kN fatigue load limit Cu; this light-to-medium rating suits fractional-horsepower drives and instruments — for conveying or gearbox duty with shock loads, verify the equivalent dynamic load stays well below C.
• At only 25 g, 16002 is a lightweight bearing that can be handled by hand; still, press it onto the shaft with a sleeve against the inner ring — never through the balls or outer ring.
• The 15×32×8 mm envelope of 16002 gives a D/d ratio of 2.13 and 8.5 mm radial section height — a heavy section built for high-load, lower-speed duty; specifying it in a high-rpm motor generates excess heat and shortens grease life, so prefer a 62/63-series there.
• The 6.2/2.84 kN load ratings, 0.22 kN fatigue load limit Cu NTN lists the grease limiting speed at 22000 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 25 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 16002 on the 15×32×8 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 16002 in a rated drive.
• NTN's pressed-steel cage (no cage suffix) is the quiet standard for this size; for sustained running close to the limiting speed or for heavy shock duty, ask the NTN channel whether a machined-cage execution of 16002 is listed.
• 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.
