How the 619-8-2RS model number is decoded
In the miniature 61900-series, the bore is written directly after the slash as 8 mm (bores below 10 mm use the slash spelling). The envelope is 8×19×6 mm (0.315×0.748×0.236 in) with a 5.5 mm radial section height, C 1.46 kN, C0 0.465 kN and Pu 0.02 kN. SKF catalogues the sealed execution as 619/8-2RS1: two contact elastomer lips (2RS1/2RSH spelling) over a lifetime grease fill; the lips add drag, and no reference (thermal) speed is published. Limiting speed 24000 r/min, catalogue mass 7.1 g. A thin section saves space but leaves little margin for misalignment or shaft deflection.
Typical equipment & failure modes
Common applications
- lay shafts and idler shafts
- textile and packaging machinery
- slew and indexing drives
- industrial electric motors
Known failure patterns
- contact-seal lip hardening and pre-grease loss after long high-temperature service
- grease-life expiry inside the sealed-for-life cavity, which has no relubrication path
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling once the catalogue L10 life is exceeded
Selection pitfalls — read before you substitute
- Do not preload 619-8-2RS to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
- Catalogue ratings for 619-8-2RS (C 1.46 kN, C0 0.465 kN) are SKF figures from PUB BU/P1 17000; geometry revisions can change ratings without changing the designation, so keep the catalogue edition with the specification.
- Contact seals make 619-8-2RS slower than the open 619/8 (limiting 24000 r/min) and forbid solvent washing, which destroys the lifetime grease.
- Do not pry the caps off 619-8-2RS to repack it; shield/seal damage leaves a gap that throws grease and admits dirt.
- Clearance suffixes follow the seal code in the designation stack (e.g. 619/8-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
- At 8 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
Frequently asked questions
What are the dimensions of 619-8-2RS?
The SKF 619/8-2RS1 measures 8 mm bore × 19 mm OD × 6 mm width (0.315 × 0.748 × 0.236 in), mass about 7.1 g. It has two contact rubber seals and a lifetime grease fill.
Why is there a slash in the designation 619/8-2RS1?
The slash writes a bore that falls outside the two-digit code table: 619/8 means 8 mm bore. The site slug 619-8-2RS replaces the slash with a hyphen.
What is the speed rating of 619-8-2RS?
SKF publishes only the 24000 r/min limiting speed for this execution; sealed variants have no thermal reference speed because seal and grease life govern.
What is the difference between 619-8-2RS and a same-bore 62-series bearing?
Section height differs: 619-8-2RS has a 5.5 mm radial section and C 1.46 kN; always match d, D and B — same bore alone never makes two bearings interchangeable.
