How the 61814-2RS model number is decoded
61814-2RS 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-thin 618xx section (diameter series 8 of ISO 15), multiplying bore code 14 by five gives the 70 mm bore; the 90 mm outside diameter and 10 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 70 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 61814-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.
Typical equipment & failure modes
Common applications
- packaging machinery
- space-constrained gearboxes
- clutch and transmission assemblies
- robotics and automation joints
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)
- brinelling from static overload or hammering during mounting
- false brinelling from vibration while the shaft is stationary
Selection pitfalls — read before you substitute
- Interference on a 70 mm shaft plus running heat consumes radial clearance: where the shaft runs hot or the fit is tight, order 61814 with C3 clearance and re-check the residual value after mounting.
- Only 10.0 mm of radial section separates bore and OD on the 618xx series at 70 mm: ring flex from clamping or an oval housing bore transfers straight into raceway stress, so seat roundness matters more here than on a 6214.
- Contact seals add drag and heat: 61814-2RS runs slower and cooler-limited than the open 61814; 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 61814-2RS: 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.
- 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.
- The housing bore for the 90 mm OD should be round within IT7; an oval bore pinches the outer ring of 61814-2RS and shows up later as two-point loaded raceway wear.
- SKF catalogues the contact-sealed version as 61814-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 4300 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 15000 r/min thermal reference speed.
- The 12.4/13.2 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 61814-2RS bearing?
A 61814-2RS deep-groove ball bearing has a 70 mm bore, 90 mm outer diameter and 10 mm width (2.756 × 3.543 × 0.394 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 61814-2RS 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 61800 compare with other series at the same 70 mm bore?
618 is an extra-thin section: 90×10 mm, only 10.0 mm radial section at 70 mm bore, far smaller than a 6214, for space-limited layouts at the cost of load rating and misalignment tolerance.
Are 61814 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 61814 uses the same ISO 15 envelope (70×90×10 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 61814-2RS?
In the SKF Rolling Bearings catalogue this size is listed as 61814-2RS1 — two contact elastomer seals over a lifetime grease fill, 70×90×10 mm per ISO 15. Quoted values: C 12.4 kN, C0 13.2 kN, Pu 0.56 kN, limiting speed 4300 r/min, mass 140 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61814-2RS.
