How the 6019 model number is decoded
In the 6000-series (diameter series 0 of ISO 15) the last two digits encode the bore: 6019 carries bore code 19 = 95 mm. Outside diameter 145 mm and width 24 mm come from the ISO 15 boundary-dimensions general plan. With no seal suffix the bearing is open: no shields or seals are fitted and lubrication is supplied by the application. 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. In the SKF catalogue this open execution carries the bare designation; protected variants are ordered separately as -2Z and -2RSH.
Typical equipment & failure modes
Common applications
- industrial fans and blowers
- hoists and winches
- heavy conveyors
- pulp and paper machinery
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- fretting corrosion on a loose shaft seat
- cage damage from operation beyond the limiting speed
Selection pitfalls — read before you substitute
- At 95 mm bore the ring mass is significant: heat 6019 on an induction heater (max 120 °C), never over an open flame, and plan puller access or a withdrawal sleeve now for the day it has to come off again.
- Choosing the 60xx extra-light section saves radial space at 95 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 6219 before committing to the smaller envelope.
- The open 6019 has no lubricant retention: grease escapes and contaminants migrate straight into the 95×145×24 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Storage matters for open bearings: 6019 leaves the factory with rust preventive only, so clean it and apply the service grease at assembly even if the rings look oily from the wrapper.
- Shaft and housing fillets must clear the bearing chamfer so the 24 mm-wide ring seats square; provide an undercut or withdrawal groove instead of relying on an oversized radius.
- 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 6019.
- The open 6019 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6019-2Z (shields) and 6019-2RSH (contact seals), not suffix-free 6019.
- 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 bearing?
A 6019 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 an open bearing with no seals or shields.
What does no suffix on 6019 mean?
A bare 6019 designation means open: no shields or seals, normal CN radial clearance and P0 normal tolerance unless further suffixes are ordered. The application must supply and retain the lubrication.
How does the 6000 compare with other series at the same 95 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (145×24 mm, 25.0 mm radial section) at 95 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6019 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6019 uses the same ISO 15 envelope (95×145×24 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting.
What is the SKF designation and catalogue data for 6019?
In the SKF Rolling Bearings catalogue this size is listed as 6019 — the open (unsealed) execution, 95×145×24 mm per ISO 15. Quoted values: C 63.7 kN, C0 54 kN, Pu 2.08 kN, limiting speed 6000 r/min, mass 1200 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6019.
