How the 6219 model number is decoded
6219 is supplied open, without shields or seals, so the arrangement around it must supply and retain the lubricant. 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. 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
- electrical pitting in VFD-driven motors without grounding protection
- raceway smearing under marginal lubrication at start-up
Selection pitfalls — read before you substitute
- Large bores like the 95 mm of 6219 demand clean, burr-free seats; one raised burr under a ring this size cocks the bearing and concentrates load at the raceway edge, cutting life drastically.
- 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.
- Vibration during standstill brinells the raceways of a 95 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- Axial location must clamp the ring face, not the seal area: a shoulder or circlip bearing on the seal side of the 32 mm-wide ring of 6219 drags the lip and overheats it.
- 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.
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, 2RSL) differ from the industry-neutral spelling 6219.
