How the 6010-RSR 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. SKF's low-friction seal suffix is 2RSL/2RZ (this page's industry-neutral spelling is -RSR); catalogue number 6010-2RZ.
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
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- At 50 mm bore, induction heating to roughly 80–100 °C is the clean mounting method; never exceed 120 °C, and hold 6010 against the shaft shoulder while it cools so the ring cannot creep back.
- 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 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 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.
- Measure the shaft, do not trust the drawing: a 50 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6010-RSR.
- The housing bore for the 80 mm OD should be round within IT7; an oval bore pinches the outer ring of 6010-RSR and shows up later as two-point loaded raceway wear.
- SKF catalogues the low-friction seal as 6010-2RZ (suffix -2RSL or -2RZ): a non-contact elastomer lip that runs near the open 9000 r/min limiting speed, closer to the open bearing's 18000 r/min reference than the contact-seal version. It keeps coarse debris out without the drag of a contact seal, but is not liquid-tight — use 2RSH for wet or fine-dust positions.
- The 22.9/15.6 kN ratings here are SKF Explorer-class figures from catalogue PUB BU/P1 17000/1 EN (Oct 2018); SKF can revise internal geometry and ratings without changing the designation, so treat the catalogue version and date as part of the specification and re-verify for critical drives.
Frequently asked questions
What are the dimensions of a 6010-RSR bearing?
A 6010-RSR 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 lubrication does 6010-RSR need?
6010-RSR is supplied pre-greased for life and is not designed to be opened for relubrication; where a relubrication path is required, specify the open 6010 with a housing grease fitting instead.
How does the 6010 bore code work?
The last two digits of 6010 are bore code 10, giving 10 × 5 = 50 mm bore. The 80 mm outside diameter and 16 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the RSR suffix on 6010-RSR mean?
RSR means two low-friction non-contact rubber seals. They keep coarse debris out with minimal drag (speed close to the open bearing) but are not liquid-tight; use -2RS contact seals for wet or fine-dust environments.
What is the SKF designation and catalogue data for 6010-RSR?
In the SKF Rolling Bearings catalogue this size is listed as 6010-2RZ — two low-friction non-contact elastomer seals, 50×80×16 mm per ISO 15. Quoted values: C 22.9 kN, C0 15.6 kN, Pu 0.71 kN, limiting speed 9000 r/min, mass 270 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6010-RSR.
