How the 6219-ZZ model number is decoded
6219-ZZ carries two non-contact sheet-steel shields that hold the factory grease in and keep coarse debris out; they do not seal against liquids. Within the light 62xx section (diameter series 2 of ISO 15), multiplying bore code 19 by five gives the 95 mm bore; the 170 mm outside diameter and 32 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 own suffix is 2Z (this page's industry-neutral spelling is -ZZ); catalogue number 6219-2Z.
Typical equipment & failure modes
Common applications
- pulp and paper machinery
- medium and heavy industrial drives
- large gearboxes
- industrial fans and blowers
Known failure patterns
- fine-particle abrasion when non-contact shields let dust past in dirty duty
- grease aging in the shield-for-life cavity with no relubrication path
- edge loading from shaft deflection or housing misalignment
- rolling-contact fatigue spalling after the rated L10 life is exceeded
Selection pitfalls — read before you substitute
- At 95 mm bore the ring mass is significant: heat 6219 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.
- At 95 mm bore the 62xx light series is the workhorse section; its 170×32 mm envelope is what most motor and gearbox seats are machined for, so any alternative section must be checked against both this OD and this width, not the bore alone.
- Do not wash 6219-ZZ in solvent before mounting: the grease inside the shielded cavity is the service fill, and solvent creeping past the shield gap strips it out.
- Shielded 6219-ZZ units are typically greased for life; prying the shields out for regreasing usually bends them and leaves a gap that throws grease in service.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6219-C3. No clearance suffix means normal CN clearance.
- The housing bore for the 170 mm OD should be round within IT7; an oval bore pinches the outer ring of 6219-ZZ and shows up later as two-point loaded raceway wear.
- SKF spells the shielded version 6219-2Z (one shield: 6219-Z), not "-ZZ": the suffix language differs by brand even though the ISO envelope is identical, so quote the brand designation when ordering.
- The single-shield execution 6219-Z is a distinct order number in catalogue 17000: it suits open gears or oil-bath arrangements where the unshielded face faces the lubricant, and it is not interchangeable with the double-shield 6219-2Z for high-contamination positions.
- 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-ZZ bearing?
A 6219-ZZ 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 fitted with two non-contact metallic shields.
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.
Are 6219 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6219 uses the same ISO 15 envelope (95×170×32 mm). Load ratings, limiting speeds, clearance, precision class and sealing design can differ, so verify those in the supplier catalogue when substituting. Seal suffixes also differ by brand (2RS, DDU, LLU, 2RSL and similar).
What internal clearance does 6219-ZZ have?
Unless a clearance suffix says otherwise, 6219-ZZ 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 6219 and verify the residual clearance after mounting.
What is the SKF designation and catalogue data for 6219-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6219-2Z — two non-contact sheet-metal shields, 95×170×32 mm per ISO 15. Quoted values: C 114 kN, C0 81.5 kN, Pu 3 kN, limiting speed 4000 r/min, mass 2700 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6219-ZZ.
