How the W6002-ZZ model number is decoded
The W prefix denotes SKF stainless steel deep-groove bearings (X108CrMo17 / AISI 440C class rings). In the 6000-series, bore code 02 follows the 10/12/15/17 mm exception table, so 6002 fits a 15 mm shaft. Envelope 15×32×9 mm (0.591×1.26×0.354 in), C 4.88 kN, C0 2.8 kN, Pu 0.12 kN; limiting speed 26000 r/min and mass 29 g. SKF spells the double shield W 6002-2Z (suffix 2Z); the shields are non-contact, retain grease and block coarse debris but are not liquid-tight. Stainless is chosen for corrosion and washdown duty, not for extra load — the same-envelope chrome-steel bearing rates higher.
Typical equipment & failure modes
Common applications
- washdown-duty equipment
- chemical and marine atmospheres
- medical and laboratory devices
- small pumps handling corrosive media
Known failure patterns
- seal and grease failure before the rings corrode in sustained washdown service
- surface staining and pitting when even the stainless steel is left unlubricated in salty or acidic duty
- fine-particle abrasion when non-contact shields let dust through in a dirty environment
- grease aging inside the shielded cavity with no relubrication path
Selection pitfalls — read before you substitute
- Temperatures above roughly 300 °C temper the stainless races; even standard greases fail far earlier — keep W6002-ZZ inside the quoted grease temperature range.
- W-prefix stainless rings (X108CrMo17 / AISI 440C class) resist moisture and weak chemicals but will still rust in chloride-rich or salt-spray duty without protection — W6002-ZZ is not marine-grade stainless.
- The stainless steel is martensitic and MAGNETIC; do not reject W6002-ZZ over magnetism — only austenitic grades are non-magnetic, and those are too soft for bearing raceways.
- Stainless bearings carry lower load ratings than chrome steel of the same envelope: W6002-ZZ is quoted at C 4.88 kN versus the 9 mm-wide 52100 version — do not swap on dimensions alone.
- Fillet radii must clear the W6002-ZZ chamfer so the 9 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Mount by heating the inner ring (max 120 °C) — driving W6002-ZZ home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of the stainless W6002-ZZ?
SKF W 6002-2Z measures 15×32×9 mm (0.591×1.26×0.354 in), about 29 g, C 4.88 kN.
What does the W in W 6002-2Z mean?
W is the SKF prefix for stainless steel deep-groove bearings (rings in X108CrMo17 / AISI 440C class); the rest of the designation follows the normal series and bore rules.
Can I replace a chrome-steel bearing with stainless W6002-ZZ?
The envelope matches, but stainless rates lower (C 4.88 kN for W 6002-2Z); for corrosive environments that trade-off is intended, for high loads it shortens life.
Is the stainless bearing magnetic?
Yes. Bearing stainless steels are martensitic (hardened) and magnetic; non-magnetic austenitic grades cannot be hardened enough for raceways and balls.
