How the 6009-ZZ model number is decoded
6009-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 09 by five gives the 45 mm bore; the 75 mm outside diameter and 16 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 45 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 6009-2Z.
Typical equipment & failure modes
Common applications
- agricultural equipment
- fans and blowers
- electric motors
- centrifugal pumps
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
- A 45 mm shaft for 6009 should be finished to Ra ≤ 1.6 µm with square seating faces; at this bore a scored or oval journal shows up directly as running noise and early raceway damage.
- The 60xx extra-light section at 45 mm bore uses a smaller 75 mm OD than a 6209; 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: 6009-ZZ blocks chips and coarse dust but is not waterproof — do not install it expecting a pressure-wash seal, step up to 6009-2RS for that.
- Do not wash 6009-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.
- Never mix components between two 6009-ZZ units: rings, cage and balls are factory-matched and are not field-interchangeable, even between identical designations.
- Suffixes stack in a defined order — clearance follows the seal code, e.g. 6009-C3. No clearance suffix means normal CN clearance.
- SKF spells the shielded version 6009-2Z (one shield: 6009-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 6009-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 6009-2Z for high-contamination positions.
- The 22.1/14.6 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 6009-ZZ bearing?
A 6009-ZZ deep-groove ball bearing has a 45 mm bore, 75 mm outer diameter and 16 mm width (1.772 × 2.953 × 0.63 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
What does the ZZ suffix on 6009-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 45 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (75×16 mm, 15.0 mm radial section) at 45 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6009 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6009 uses the same ISO 15 envelope (45×75×16 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 is the SKF designation and catalogue data for 6009-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6009-2Z — two non-contact sheet-metal shields, 45×75×16 mm per ISO 15. Quoted values: C 22.1 kN, C0 14.6 kN, Pu 0.64 kN, limiting speed 10000 r/min, mass 250 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6009-ZZ.
