How the 61819-2RS model number is decoded
In the 61800-series (diameter series 8 of ISO 15) the last two digits encode the bore: 61819 carries bore code 19 = 95 mm. Outside diameter 120 mm and width 13 mm come from the ISO 15 boundary-dimensions general plan. Suffix -2RS denotes two contact-type elastomer seals over a lifetime grease fill; the sealing lips add drag compared with open or shielded versions. For normal-load mounting with a rotating inner ring on a 95 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's contact-seal catalogue number is 61819-2RS1 (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)
- rolling-contact fatigue spalling after the rated L10 life is exceeded
- brinelling from static overload or hammering during mounting
Selection pitfalls — read before you substitute
- Large bores like the 95 mm of 61819-2RS demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
- Only 12.5 mm of radial section separates bore and OD on the 618xx series at 95 mm: ring flex from clamping or an oval housing bore transfers straight into raceway stress, so seat roundness matters more here than on a 6219.
- Heat is the enemy of the sealed 61819-2RS: 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.
- Never wash a sealed 61819-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- Measure the shaft, do not trust the drawing: a 95 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 61819-2RS.
- Vibration during standstill brinells the raceways of a 95 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- SKF catalogues the contact-sealed version as 61819-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 3000 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 11000 r/min thermal reference speed.
- The 19.9/17.6 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 61819-2RS bearing?
A 61819-2RS deep-groove ball bearing has a 95 mm bore, 120 mm outer diameter and 13 mm width (3.74 × 4.724 × 0.512 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
What lubrication does 61819-2RS need?
61819-2RS is supplied pre-greased for life and is not designed to be opened for relubrication; where a relubrication path is required, specify the open 61819 with a housing grease fitting instead.
How does the 61819 bore code work?
The last two digits of 61819 are bore code 19, giving 19 × 5 = 95 mm bore. The 120 mm outside diameter and 13 mm width follow the ISO 15 diameter series, not the bore code alone.
What does the 2RS suffix on 61819-2RS 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.
What is the SKF designation and catalogue data for 61819-2RS?
In the SKF Rolling Bearings catalogue this size is listed as 61819-2RS1 — two contact elastomer seals over a lifetime grease fill, 95×120×13 mm per ISO 15. Quoted values: C 19.9 kN, C0 17.6 kN, Pu 0.93 kN, limiting speed 3000 r/min, mass 310 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 61819-2RS.
