How the 6202-NSK model number is decoded

6202 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. 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. 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

• At 15 mm bore, induction heating to roughly 80–100 °C is the clean mounting method; never exceed 120 °C, and hold 6202 against the shaft shoulder while it cools so the ring cannot creep back.
• 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.
• Storage matters for open bearings: 6202-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.
• Open bearings tolerate the highest speeds in the 6200-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6202 units.
• 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 6202-NSK.
• Never mix components between two 6202-NSK units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
• The open 6202 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 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 6202 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 does not recommend washing new shielded or sealed bearings; the rust-preventive film on open units is compatible with standard lithium greases and needs no removal unless the application demands a special fill.
• When replacing a failed unit, inspect the shaft and housing seats before fitting the new 6202 — a new bearing pressed onto a worn or oval seat reproduces the original failure mode in a fraction of its expected life.
