How the 6017-ZZ model number is decoded
6017-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 extra-light 60xx section (diameter series 0 of ISO 15), multiplying bore code 17 by five gives the 85 mm bore; the 130 mm outside diameter and 22 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 85 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 6017-2Z.
Typical equipment & failure modes
Common applications
- large gearboxes
- industrial fans and blowers
- hoists and winches
- heavy conveyors
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
- raceway smearing under marginal lubrication at start-up
- edge loading from shaft deflection or housing misalignment
Selection pitfalls — read before you substitute
- Large bores like the 85 mm of 6017-ZZ 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 60xx extra-light section at 85 mm bore uses a smaller 130 mm OD than a 6217; load ratings are lower, so do not replace a failed 62-series bearing with a 60-series without re-rating the load.
- Do not wash 6017-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 6017-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.
- Never mix components between two 6017-ZZ units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- Vibration during standstill brinells the raceways of a 85 mm bearing at ball spacing; if the machine sits idle next to running equipment, turn the shaft over periodically or isolate the arrangement.
- SKF spells the shielded version 6017-2Z (one shield: 6017-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 6017-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 6017-2Z for high-contamination positions.
- The 52/43 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 6017-ZZ bearing?
A 6017-ZZ deep-groove ball bearing has a 85 mm bore, 130 mm outer diameter and 22 mm width (3.346 × 5.118 × 0.866 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
How should 6017-ZZ be mounted?
Apply the mounting force to the ring being fitted: on a 85 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 6017-ZZ need?
6017-ZZ is greased at the factory and the shields hold the fill for the bearing's service life; relubrication is not intended, and adding grease through the shield gap usually forces dirt in with it.
How does the 6017 bore code work?
The last two digits of 6017 are bore code 17, giving 17 × 5 = 85 mm bore. The 130 mm outside diameter and 22 mm width follow the ISO 15 diameter series, not the bore code alone.
What is the SKF designation and catalogue data for 6017-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6017-2Z — two non-contact sheet-metal shields, 85×130×22 mm per ISO 15. Quoted values: C 52 kN, C0 43 kN, Pu 1.76 kN, limiting speed 5300 r/min, mass 940 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6017-ZZ.
