How the 6002-ZZ-NTN model number is decoded

6002-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 extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 15 by five gives the 15 mm bore; the 32 mm outside diameter and 9 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 15 mm shaft under normal load, catalogue practice seats it on a j5 shaft fit with an H7 housing bore — confirm against the actual load direction and magnitude before committing. NTN catalogue order number: 6002ZZ (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

• Interference on a 15 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6002 with C3 clearance and re-check the residual value after mounting.
• Choosing the 60xx extra-light section saves radial space at 15 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6215 before committing to the smaller envelope.
• Do not wash 6002-ZZ-NTN in solvent before mounting: the grease inside the shielded cavity is the service fill, and solvent creeping past the shield gap strips it out.
• Shielded 6002-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.
• Suffixes stack in a defined order — clearance follows the seal code, e.g. 6002-ZZ-NTN-C3. No clearance suffix means normal CN clearance.
• Measure the shaft, do not trust the drawing: a 15 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6002-ZZ-NTN.
• NTN catalogues the shielded version as 6002ZZ — 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.
• At 15 mm bore the 6002 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 6002 at 18000 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 seal lip.
• NTN rates 6002 at 6.2 kN dynamic (C) and 2.84 kN static (C0), 0.2 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 30 g, 6002 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 15×32×9 mm envelope of 6002 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, 0.2 kN fatigue load limit Cu NTN lists the grease limiting speed at 18000 r/min for this designation; oil-mist or jet lubrication raises the ceiling but requires a sealed-housing review. and 30 g mass here are NTN Ball and Roller Bearings CAT.No.2203-3/E figures for 6002ZZ on the 15×32×9 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6002 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.
• 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.
