How the 6010-RSR-NSK model number is decoded
6010-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 10 by five gives the 50 mm bore; the 80 mm outside diameter and 16 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 50 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 6010VV), 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 electric motors
- centrifugal and positive-displacement pumps
- gearboxes and speed reducers
- conveyor drives
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
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- Temperature rise and interference fits consume internal clearance on this 50 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 6010 with C3 for those conditions.
- Choosing the 60xx extra-light section saves radial space at 50 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6210 before committing to the smaller envelope.
- The low-drag lip of 6010-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 6010-RSR-NSK does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 50 mm bore position before relying on it as sealed-for-life.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6010-RSR-NSK-C3. No clearance suffix means normal CN clearance.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- NSK catalogues this low-friction non-contact seal as 6010VV (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 50 mm bore puts 6010 in NSK's general-purpose industrial range; the standard pressed-steel cage and CN clearance cover most electric-motor and 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.
- At 24 kN dynamic load rating (C) and 16.6 kN static (C0), 6010 is a medium-load NSK bearing suitable for most electric-motor and pump duty; the C0/C0r ratio matters for preloaded or thrust-loaded arrangements, so confirm the static safety factor with the NSK catalogue.
- At 261 g, 6010 requires a soft-jaw vise or arbor press for mounting — never hammer it onto the shaft, and support the opposite ring to avoid brinelling the raceways.
- The 50×80×16 mm envelope of 6010 gives a D/d ratio of 1.60 and 15.0 mm radial section height — this NSK thin section saves space but is sensitive to misalignment and shock; confirm the housing stays round within IT7 and the shaft does not deflect past the raceway contact angle under load.
- The 24/16.6 kN load ratings, mass 261 g here are NSK Rolling Bearings E1103 Part C catalogue figures for 6010VV on the 50×80×16 mm ISO 15 envelope; internal geometry and ratings legitimately differ between brands, so re-verify before substituting another manufacturer's 6010 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 6010; in motor duty where heat build-up matters, VV is the usual compromise between debris protection and speed capability.
- 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 6010-RSR-NSK bearing?
A 6010-RSR-NSK deep-groove ball bearing has a 50 mm bore, 80 mm outer diameter and 16 mm width (1.969 × 3.15 × 0.63 in), per ISO 15 boundary dimensions. It is fitted with two low-friction non-contact rubber seals.
What internal clearance does 6010-RSR-NSK have?
Unless a clearance suffix says otherwise, 6010-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 6010 and verify the residual clearance after mounting.
How should 6010-RSR-NSK be mounted?
Apply the mounting force to the ring being fitted: on a 50 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 6010?
NSK uses suffix DDU for the contact rubber seal (catalogue number 6010VV), 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 50×80×16 mm ISO 15 envelope.
What is the difference between NSK VV and DDU seals?
VV is a non-contact rubber seal: low torque, speed close to the open bearing, dust-tight but not liquid-tight. DDU is a contact rubber seal: far better exclusion of moisture and fine dust, at the cost of a lower speed ceiling and higher running torque. 6010VV keeps the same ISO 15 envelope either way.
