How the 6202-RSR-NSK model number is decoded

6202-RSR uses two non-contact elastomer lips with very low drag; coarse debris stays out, but the bearing is not liquid-tight. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 15 by five gives the 15 mm bore; the 35 mm outside diameter and 11 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. NSK's non-contact seal suffix is VV (catalogue number 6202VV), mapped here from the industry-neutral -RSR spelling; speed capability is close to the open bearing but VV is not liquid-tight.

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 6202 with C3 clearance and re-check the residual value after mounting.
• The 62xx light series is the default general-purpose section at 15 mm bore; before upgrading to a 6315 for extra capacity, confirm the housing accepts a 35 mm OD and 11 mm width — it is not a drop-in swap.
• RSR low-friction seals on 6202-RSR-NSK run faster than contact-seal 6202-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 6202-2RS instead.
• The low-drag lip of 6202-RSR-NSK barely touches the inner ring; after long shelf storage the grease can separate, so rotate the rings by hand and confirm smooth, silent running before fitting.
• Never mix components between two 6202-RSR-NSK units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• The housing bore for the 35 mm OD should be round within IT7; an oval bore pinches the outer ring of 6202-RSR-NSK and shows up later as two-point loaded raceway wear.
• NSK catalogues this low-friction non-contact seal as 6202VV (suffix VV), mapped here from the industry-neutral -RSR spelling. NSK rates its speed capability close to the open bearing, but VV is not liquid-tight — for wet or fine-dust duty step up to the DDU contact seal (industry-neutral -2RS).
• At 15 mm bore the 6202 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 6202 at 8.4 kN dynamic (C) and 3.75 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 45 g, 6202 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 15×35×11 mm envelope of 6202 gives a D/d ratio of 2.33 and 10.0 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 8.4/3.75 kN load ratings, mass 45 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6202VV on the 15×35×11 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6202 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.
• NSK's VV non-contact seal keeps frictional torque close to the open 6202; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
• Standard P0 runout from NSK is adequate up to the catalogue limiting speed on ground shaft seats; spindle or instrument positions should specify P6/P5 accuracy explicitly — it is a different order code, not a sorting of standard stock.
