How the 6000-RSR-NSK model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6000 carries bore code 10 = 10 mm. Outside diameter 26 mm and width 8 mm come from the ISO 15 boundary-dimensions general plan. Suffix -RSR denotes two low-friction non-contact elastomer seals; they keep coarse debris out with minimal drag but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 10 mm shaft, typical catalogue practice is a j5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. NSK's non-contact seal suffix is VV (catalogue number 6000VV), 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
Common applications
- industrial fans
- industrial electric motors
- centrifugal and positive-displacement pumps
- gearboxes and speed reducers
Known failure patterns
- ingress of fine dust or moisture past the non-contact lip in dirty or wet duty (RSR is not liquid-tight)
- lip-lubricant starvation if the bearing runs dry for extended periods
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Interference on a 10 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 6000 with C3 clearance and re-check the residual value after mounting.
- The 60xx extra-light section at 10 mm bore uses a smaller 26 mm OD than a 6210; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- RSR low-friction seals on 6000-RSR-NSK run faster than contact-seal 6000-2RS but let fine dust and moisture past the non-contact lip; in dirty or wet duty specify 6000-2RS instead.
- The low-drag lip of 6000-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.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 26 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6000-RSR-NSK.
- Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 8 mm-wide ring of 6000-RSR-NSK drags the lip and overheats it.
- NSK catalogues this low-friction non-contact seal as 6000VV (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 10 mm bore the 6000 sits in NSK's miniature 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 6000 at 5.05 kN dynamic (C) and 1.97 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 18 g, 6000 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 10×26×8 mm envelope of 6000 gives a D/d ratio of 2.60 and 8.0 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 5.05/1.97 kN load ratings, mass 18 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6000VV on the 10×26×8 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6000 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 supplies its sealed units pre-greased for general duty between roughly -10 and +110 °C; low-temperature, food-grade and high-temperature fills are special executions — ask at order time, because DDU/VV units are not designed to be opened and repacked.
- 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.
Frequently asked questions
What are the dimensions of a 6000-RSR-NSK bearing?
A 6000-RSR-NSK deep-groove ball bearing has a 10 mm bore, 26 mm outer diameter and 8 mm width (0.394 × 1.024 × 0.315 in), per ISO 15 boundary dimensions. It is fitted with two low-friction non-contact rubber seals.
What internal clearance does 6000-RSR-NSK have?
Unless a clearance suffix says otherwise, 6000-RSR-NSK is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6000 and verify the residual clearance after mounting.
How should 6000-RSR-NSK be mounted?
Apply the mounting force to the ring being fitted: on a 10 mm shaft seat the press load must pass through the inner-ring face only. A fitting sleeve and an arbor press are normally sufficient at this size. Never strike the outer ring, the cage or the seals.
What is the NSK suffix for a sealed 6000?
NSK uses suffix DDU for the contact rubber seal (catalogue number 6000VV), VV for the non-contact rubber seal, and ZZ for steel shields. The industry-neutral spellings on this page (-2RS / -RSR / -ZZ) map to those NSK suffixes while keeping the 10×26×8 mm ISO 15 envelope.
Does NSK offer 6000 with C3 clearance?
NSK lists C3 (and C4) internal-clearance options for most deep-groove sizes under the same base designation; the clearance is fixed at manufacture, so specify it at order time rather than planning to adjust later.
