How the 6006-ZZ model number is decoded
6006-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 06 by five gives the 30 mm bore; the 55 mm outside diameter and 13 mm width follow the same boundary-dimension plan. For a rotating inner ring on a 30 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 6006-2Z.
Typical equipment & failure modes
Common applications
- small gearboxes
- conveyors and drives
- agricultural equipment
- 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
- A 30 mm shaft for 6006 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.
- Choosing the 60xx extra-light section saves radial space at 30 mm bore, but the trade-off is rating: if the drive sees shock or frequent start-stop cycles, re-check the L10 life against a 6206 before committing to the smaller envelope.
- Do not wash 6006-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 6006-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.
- Measure the shaft, do not trust the drawing: a 30 mm nominal journal worn by even 0.02 mm turns an interference seat into a creeping fit that frets the bore of 6006-ZZ.
- The housing bore for the 55 mm OD should be round within IT7; an oval bore pinches the outer ring of 6006-ZZ and shows up later as two-point loaded raceway wear.
- SKF spells the shielded version 6006-2Z (one shield: 6006-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 6006-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 6006-2Z for high-contamination positions.
- The 13.8/8.3 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 6006-ZZ bearing?
A 6006-ZZ deep-groove ball bearing has a 30 mm bore, 55 mm outer diameter and 13 mm width (1.181 × 2.165 × 0.512 in), per ISO 15 boundary dimensions. It is fitted with two non-contact metallic shields.
How does the 6000 compare with other series at the same 30 mm bore?
The second digit is the diameter series: 60 is the smallest standard section (55×13 mm, 12.5 mm radial section) at 30 mm bore — below 62/63/64 in load capacity, for light loads in compact spaces.
Are 6006 bearings from different brands interchangeable?
For boundary dimensions, yes: every brand's 6006 uses the same ISO 15 envelope (30×55×13 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 6006-ZZ have?
Unless a clearance suffix says otherwise, 6006-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 6006 and verify the residual clearance after mounting.
What is the SKF designation and catalogue data for 6006-ZZ?
In the SKF Rolling Bearings catalogue this size is listed as 6006-2Z — two non-contact sheet-metal shields, 30×55×13 mm per ISO 15. Quoted values: C 13.8 kN, C0 8.3 kN, Pu 0.355 kN, limiting speed 14000 r/min, mass 120 g. Brand suffixes (2Z, 2RSH, 2RSL) differ from the industry-neutral spelling 6006-ZZ.
