How the 6017-ZZ model number is decoded
In the 6000-series (ISO 15 diameter series 0) the last two digits encode the bore: 6017 carries bore code 17 = 85 mm. Outside diameter 130 mm and width 22 mm come from the ISO 15 boundary-dimensions general plan. Suffix -ZZ denotes two non-contact metallic shields; they retain grease and block coarse debris but are not liquid-tight. For normal-load mounting with a rotating inner ring on a 85 mm shaft, typical catalogue practice is a k5 shaft seat with an H7 housing bore — verify against the actual load direction and magnitude. SKF's own suffix is 2Z (this page's industry-neutral spelling is -ZZ); catalogue number 6017-2Z.
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
- 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 85 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 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.
- ZZ shields are non-contact: 6017-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6017-2RS for that.
- 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.
- Assign fits by which ring rotates: an interference shaft fit for a rotating inner ring; if the outer ring rotates instead, reverse the logic — a loose rotating ring creeps and frets its seat.
- 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. Geometry-based estimated mass is about 853 g for a steel-cage unit; catalogue masses vary slightly with seal and cage design.
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 does the ZZ suffix on 6017-ZZ mean?
ZZ means two non-contact sheet-metal shields, one each side. They retain factory grease and block coarse particles with little friction, but do not seal against liquids, fine dust or pressure washing.
How does the 6000 compare with other series at the same 85 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (130×22 mm, 22.5 mm radial section) at 85 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
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) differ from the industry-neutral spelling 6017-ZZ.
