How the 6002-NSK model number is decoded

In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6002 carries bore code 15 = 15 mm. Outside diameter 32 mm and width 9 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 NSK catalogue this open execution carries the bare designation; protected variants are ordered separately with suffixes ZZ (steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals).

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.
• The 60xx extra-light section at 15 mm bore uses a smaller 32 mm OD than a 6215; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
• The open 6002-NSK has no lubricant retention: grease escapes and contaminants migrate straight into the 15×32×9 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
• Storage matters for open bearings: 6002-NSK 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.
• Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 9 mm-wide ring of 6002-NSK drags the lip and overheats it.
• The housing bore for the 32 mm OD should be round within IT7; an oval bore pinches the outer ring of 6002-NSK and shows up later as two-point loaded raceway wear.
• The open 6002 has no integral sealing; in the NSK E1103 catalogue the protected variants carry suffixes ZZ (non-contact steel shields), VV (non-contact rubber seals) and DDU (contact rubber seals). NSK does not offer a low-torque contact seal equivalent to NTN's LLH in this catalogue — for high-speed sealed duty specify the VV non-contact seal and an external housing labyrinth.
• At 15 mm bore the 6002 sits in NSK's small-bore range; NSK ships these sizes with a pressed-steel cage and P0 tolerance as standard, and NSK's EA (extra-precision) or P5 class is a special-order upgrade for spindle duty — do not assume catalogue P0 figures hold for instrument use without an NSK engineering check.
• NSK rates 6002 at 6.15 kN dynamic (C) and 2.84 kN static (C0); 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 31 g, 6002 is a lightweight NSK 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 NSK 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 6.15/2.84 kN load ratings, mass 31 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6002 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. NSK does not tabulate reference or limiting speeds in the E1103 Part C dimension tables used for this page — consult NSK's separate speed-rating tables before high-speed service.
• Keep NSK bearings in the original packaging until fitting: the wrapper carries the production lot, and the unopened shelf life of greased sealed units is typically quoted at three to five years in dry, vibration-free storage.
• NSK's VV non-contact seal keeps frictional torque close to the open 6002; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
