How the 6219 model number is decoded
In the 6200-series (ISO 15 diameter series 2) the last two digits encode the bore: 6219 carries bore code 19 = 95 mm. Outside diameter 170 mm and width 32 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
- hoists and winches
- heavy conveyors
- pulp and paper machinery
- medium and heavy industrial drives
Known failure patterns
- contamination wear from dust and dirt ingress through the open arrangement
- lubricant starvation when no regreasing interval is maintained
- cage damage from operation beyond the limiting speed
- electrical pitting in VFD-driven motors without grounding protection
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 62xx light series is the default general-purpose section at 95 mm bore; before upgrading to a 6319 for extra capacity, confirm the housing accepts a 170 mm OD and 32 mm width — it is not a drop-in swap.
- The open 6219 has no lubricant retention: grease escapes and contaminants migrate straight into the 95×170×32 mm raceway, so specify a sealed arrangement for dusty or washdown duty.
- Open bearings tolerate the highest speeds in the 6200-series but need a defined regreasing interval; run-to-failure lubrication is the dominant cause of early failure in open 6219 units.
- Deep-groove ball bearings tolerate only minutes of misalignment; if the 170 mm housing cannot be aligned, switch to a self-aligning type rather than shimming 6219.
- The open 6219 needs external sealing and application-supplied lubrication; in the SKF catalogue the protected variants are separate order numbers 6219-2Z (shields) and 6219-2RSH (contact seals), not suffix-free 6219.
- The 114/81.5 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 6219 bearing?
A 6219 deep-groove ball bearing has a 95 mm bore, 170 mm outer diameter and 32 mm width (3.74 × 6.693 × 1.26 in), per ISO 15 boundary dimensions. It is an open bearing with no seals or shields. Geometry-based estimated mass is about 2549 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
How does the 6219 bore code work?
The last two digits of 6219 are bore code 19, giving 19 × 5 = 95 mm bore. The 170 mm outside diameter and 32 mm width follow the ISO 15 diameter series, not the bore code alone.
What does no suffix on 6219 mean?
A bare 6219 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 6200 compare with other series at the same 95 mm bore?
The '2' is the light diameter series: 170×32 mm with a 37.5 mm radial section at 95 mm bore. A 6319 on the same bore is larger and higher-rated; a 6019 is smaller and lower-rated.
What is the SKF designation and catalogue data for 6219?
In the SKF Rolling Bearings catalogue this size is listed as 6219 — the open (unsealed) execution, 95×170×32 mm per ISO 15. Quoted values: C 114 kN, C0 81.5 kN, Pu 3 kN, limiting speed 5000 r/min, mass 2650 g. Brand suffixes (2Z, 2RSH) differ from the industry-neutral spelling 6219.
