How the W6007 model number is decoded
The W prefix denotes SKF stainless steel deep-groove bearings (X108CrMo17 / AISI 440C class rings). In the 6000-series, the last two digits encode the bore: 6007 carries code 07 = 35 mm (code × 5). Envelope 35×62×14 mm (1.378×2.441×0.551 in), C 13.8 kN, C0 10.2 kN, Pu 0.44 kN; limiting speed 15000 r/min and mass 138 g. The open W 6007 carries no shields or seals and relies on application lubrication and external sealing. 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
- food and beverage conveyors
- pharmaceutical and packaging machines
- washdown-duty equipment
- chemical and marine atmospheres
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
- contamination wear when the open arrangement is used without external seals
- lubricant starvation where no regreasing interval is maintained
Selection pitfalls — read before you substitute
- Temperatures above roughly 300 °C temper the stainless races; even standard greases fail far earlier — keep W6007 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 — W6007 is not marine-grade stainless.
- The stainless steel is martensitic and MAGNETIC; do not reject W6007 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: W6007 is quoted at C 13.8 kN versus the 14 mm-wide 52100 version — do not swap on dimensions alone.
- At 35 mm bore, C3 clearance is the safe choice when interference fits plus temperature rise consume the CN clearance; a hot tight bearing with no residual clearance fails fast.
- Do not preload W6007 to silence it: a deep-groove ball bearing is not angular-contact, and axial preload only raises temperature and shortens grease life.
Frequently asked questions
What are the dimensions of the stainless W6007?
SKF W 6007 measures 35×62×14 mm (1.378×2.441×0.551 in), about 138 g, C 13.8 kN.
What does the W in W 6007 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 W6007?
The envelope matches, but stainless rates lower (C 13.8 kN for W 6007); 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.
