How the 6005-2RS model number is decoded
6005-2RS is closed by two contacting elastomer lips over a lifetime grease fill; the lips add friction, so the speed ceiling sits below the open execution. Within the extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 05 by five gives the 25 mm bore; the 47 mm outside diameter and 12 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 25 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 contact-seal catalogue number is 6005-2RSH (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.
Typical equipment & failure modes
Common applications
- electric motors
- centrifugal pumps
- small gearboxes
- conveyors and drives
Known failure patterns
- seal-lip hardening and loss of pre-grease in sustained high-temperature service
- grease-life expiry in the sealed-for-life cavity (no relubrication path)
- cage damage from operation beyond the limiting speed
- electrical pitting in VFD-driven motors without grounding protection
Selection pitfalls — read before you substitute
- A 25 mm shaft for 6005 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.
- Choosing the 60xx extra-light section saves radial space at 25 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 6205 before committing to the smaller envelope.
- Contact seals add drag and heat: 6005-2RS runs slower and cooler-limited than the open 6005; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
- Heat is the enemy of the sealed 6005-2RS: sustained running near the lip temperature limit hardens the rubber, after which grease escapes and dirt tracks in — watch the housing temperature in hot drives.
- A 25 mm bore listing showing the right d/D/B but no standard or precision-class reference may be a loose-tolerance import; measure bore/OD spread before fitting it to a machined shaft.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6005-C3. No clearance suffix means normal CN clearance.
- SKF catalogues the contact-sealed version as 6005-2RSH (older printings may read -2RS1); it is shipped pre-greased and its 9500 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 32000 r/min thermal reference speed. The single-seal catalogue number is 6005-RSH, used where one shaft side needs external relubrication.
- A one-seal execution 6005-RSH exists for arrangements that lubricate through the open side; fitting 6005-2RSH instead means lifetime grease and no external oil supply — mixing the two in the same shaft can starve the sealed position.
- The 11.9/6.55 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 6005-2RS bearing?
A 6005-2RS deep-groove ball bearing has a 25 mm bore, 47 mm outer diameter and 12 mm width (0.984 × 1.85 × 0.472 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
What does the 2RS suffix on 6005-2RS mean?
2RS means two contact elastomer seals, one each side, usually over a lifetime grease fill. Sealing against dust and moisture is better than ZZ shields, but the lip drag lowers the speed and temperature ceiling.
How does the 6000 compare with other series at the same 25 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (47×12 mm, 11.0 mm radial section) at 25 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6005 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6005 uses the same ISO 15 envelope (25×47×12 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 6005-2RS?
In the SKF Rolling Bearings catalogue this size is listed as 6005-2RSH — two contact elastomer seals over a lifetime grease fill, 25×47×12 mm per ISO 15. Quoted values: C 11.9 kN, C0 6.55 kN, Pu 0.275 kN, limiting speed 9500 r/min, mass 81 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6005-2RS.
