How the 6006-RSR-NSK model number is decoded

6006-RSR uses two non-contact elastomer lips with very low drag; coarse debris stays out, but the bearing is not liquid-tight. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 06 by five gives the 30 mm bore; the 55 mm outside diameter and 13 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 30 mm shaft under normal load, catalogue practice seats it on a k5 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 6006VV), 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

• A 30 mm shaft for 6006 should be finished to Ra ≤ 1.6 µm with square seating faces; at this bore a scored or oval journal shows up directly as running noise and early raceway damage.
• The 60xx extra-light section at 30 mm bore uses a smaller 55 mm OD than a 6206; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
• The low-drag lip of 6006-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.
• The non-contact lip of 6006-RSR-NSK does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 30 mm bore position before relying on it as sealed-for-life.
• Deep-groove ball bearings tolerate only minutes of misalignment; if the 55 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6006-RSR-NSK.
• Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
• NSK catalogues this low-friction non-contact seal as 6006VV (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).
• The 30 mm bore puts 6006 in NSK's light industrial range; the standard pressed-steel cage and CN clearance cover most fractional-horsepower motor and small-pump duty. NSK's VV non-contact seal is the high-speed choice here — DDU contact seal costs roughly 30–40% of the open-bearing speed ceiling.
• NSK rates 6006 at 14.6 kN dynamic (C) and 8.3 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 116 g, 6006 is light enough for hand assembly but should be pressed on with a fitting sleeve against the inner ring; do not strike the outer ring or cage with a hammer.
• The 30×55×13 mm envelope of 6006 gives a D/d ratio of 1.83 and 12.5 mm radial section height — a standard NSK medium section that balances load capacity and speed; for this geometry the pressed-steel cage is adequate up to NSK's listed speed ratings, and C3 clearance is the common choice for hot shafts.
• The 14.6/8.3 kN load ratings, mass 116 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6006VV on the 30×55×13 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6006 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.
• When replacing a failed unit, inspect the shaft and housing seats before fitting the new 6006 — a new bearing pressed onto a worn or oval seat reproduces the original failure mode in a fraction of its expected life.
• NSK's VV non-contact seal keeps frictional torque close to the open 6006; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
