How the 6015-RSR model number is decoded
6015-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 15 by five gives the 75 mm bore; the 115 mm outside diameter and 20 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 75 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 6015-2RZ.
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
- false brinelling from vibration while the shaft is stationary
- fretting corrosion on a loose shaft seat
Selection pitfalls — read before you substitute
- Temperature rise and interference fits consume internal clearance on this 75 mm bore: a CN bearing on a tight, hot shaft can lose all residual clearance — size 6015 with C3 for those conditions.
- The 60xx extra-light section at 75 mm bore uses a smaller 115 mm OD than a 6215; 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 6015-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 6015-RSR does not retain a lifetime grease fill the way a contact seal does; confirm the regreasing interval for the 75 mm bore position before relying on it as sealed-for-life.
- Never mix components between two 6015-RSR units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6015-C3. No clearance suffix means normal CN clearance.
- SKF catalogues the low-friction seal as 6015-2RZ (suffix -2RSL or -2RZ): a non-contact elastomer lip that runs near the open 6000 r/min limiting speed, closer to the open bearing's 12000 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 41.6/33.5 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 6015-RSR bearing?
A 6015-RSR deep-groove ball bearing has a 75 mm bore, 115 mm outer diameter and 20 mm width (2.953 × 4.528 × 0.787 in), per ISO 15 boundary dimensions. It is fitted with two low-friction non-contact rubber seals.
What does the RSR suffix on 6015-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.
How does the 6000 compare with other series at the same 75 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (115×20 mm, 20.0 mm radial section) at 75 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6015 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6015 uses the same ISO 15 envelope (75×115×20 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting. Seal suffixes also differ by brand (2RS, DDU, LLU, 2RSL and similar).
What is the SKF designation and catalogue data for 6015-RSR?
In the SKF Rolling Bearings catalogue this size is listed as 6015-2RZ — two low-friction non-contact elastomer seals, 75×115×20 mm per ISO 15. Quoted values: C 41.6 kN, C0 33.5 kN, Pu 1.43 kN, limiting speed 6000 r/min, mass 670 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6015-RSR.
