How the 6019-2RS model number is decoded
6019-2RS 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 19 by five gives the 95 mm bore; the 145 mm outside diameter and 24 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 95 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 6019-2RS1 (older text: -2RS1), mapped here from the industry-neutral -2RS spelling.
Typical equipment & failure modes
Common applications
- large gearboxes
- industrial fans and blowers
- hoists and winches
- heavy conveyors
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)
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- Mount this 95 mm bore bearing by heating the inner ring (induction heater, max 120 °C) — never drive it home through the outer ring or balls, that brinells the raceways.
- The 60xx extra-light section at 95 mm bore uses a smaller 145 mm OD than a 6219; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- Contact seals add drag and heat: 6019-2RS runs slower and cooler-limited than the open 6019; rubber lips are generally limited to roughly 80–110 °C continuous depending on grease, and C3 clearance is the common hot-duty choice.
- Never wash a sealed 6019-2RS in solvent or press it home via the outer ring; solvent destroys the grease thickener and mounting force through the seal deforms the lip.
- Grease compatibility is not guaranteed between fills: mixing lithium and polyurea thickeners in a 6000-series position can soften the mixture and leak — clean out the old fill before switching grease types.
- Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 24 mm-wide ring of 6019-2RS drags the lip and overheats it.
- SKF catalogues the contact-sealed version as 6019-2RS1 (older printings may read -2RS1); it is shipped pre-greased and its 2800 r/min limiting speed is set by seal-lip drag and grease life versus the open bearing's 9500 r/min thermal reference speed.
- The 63.7/54 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 6019-2RS bearing?
A 6019-2RS deep-groove ball bearing has a 95 mm bore, 145 mm outer diameter and 24 mm width (3.74 × 5.709 × 0.945 in), per ISO 15 boundary dimensions. It is fitted with two contact rubber seals and is normally pre-greased.
What internal clearance does 6019-2RS have?
Unless a clearance suffix says otherwise, 6019-2RS is manufactured to normal (CN) radial internal clearance. Tight fits and hot shafts consume clearance in service — for those conditions order the C3 execution of 6019 and verify the residual clearance after mounting.
How should 6019-2RS be mounted?
Apply the mounting force to the ring being fitted: on a 95 mm shaft seat the press load must pass through the inner-ring face only. Induction heating of the inner ring (max 120 °C) is the clean method at this size. Never strike the outer ring, the cage or the seals.
What lubrication does 6019-2RS need?
6019-2RS is supplied pre-greased for life and is not designed to be opened for relubrication; where a relubrication path is required, specify the open 6019 with a housing grease fitting instead.
What is the SKF designation and catalogue data for 6019-2RS?
In the SKF Rolling Bearings catalogue this size is listed as 6019-2RS1 — two contact elastomer seals over a lifetime grease fill, 95×145×24 mm per ISO 15. Quoted values: C 63.7 kN, C0 54 kN, Pu 2.08 kN, limiting speed 2800 r/min, mass 1250 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6019-2RS.
