How the W6200-2RS model number is decoded
The W prefix denotes SKF stainless steel deep-groove bearings (X108CrMo17 / AISI 440C class rings). In the 6200-series, bore code 00 follows the 10/12/15/17 mm exception table, so 6200 fits a 10 mm shaft. Envelope 10×30×9 mm (0.394×1.181×0.354 in), C 4.36 kN, C0 2.32 kN, Pu 0.1 kN; limiting speed 16000 r/min and mass 30 g. SKF catalogues the sealed execution as W 6200-2RS1: two contact elastomer lips (2RS1/2RSH spelling) over a lifetime grease fill; the lips add drag, and no reference (thermal) speed is published. 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
- chemical and marine atmospheres
- medical and laboratory devices
- small pumps handling corrosive media
- bicycle and outdoor equipment
Known failure patterns
- surface staining and pitting when even the stainless steel is left unlubricated in salty or acidic duty
- seal and grease failure before the rings corrode in sustained washdown service
- contact-seal lip hardening and pre-grease loss after long high-temperature service
- grease-life expiry inside the sealed-for-life cavity, which has no relubrication path
Selection pitfalls — read before you substitute
- 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 — W6200-2RS is not marine-grade stainless.
- The stainless steel is martensitic and MAGNETIC; do not reject W6200-2RS 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: W6200-2RS is quoted at C 4.36 kN versus the 9 mm-wide 52100 version — do not swap on dimensions alone.
- Food, pharmaceutical and washdown positions need food-grade grease (e.g. NSF H1 registered) inside W6200-2RS; standard fill is industrial grease unless specified otherwise.
- Fillet radii must clear the W6200-2RS chamfer so the 9 mm-wide ring seats square; an oversized shaft radius creates point contact on the ring face.
- Deep-groove geometry tolerates only minutes of misalignment; if the 30 mm housing bore cannot be aligned, move to a self-aligning bearing rather than shimming W6200-2RS.
Frequently asked questions
What are the dimensions of the stainless W6200-2RS?
SKF W 6200-2RS1 measures 10×30×9 mm (0.394×1.181×0.354 in), about 30 g, C 4.36 kN.
What does the W in W 6200-2RS1 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.
What grease is supplied in W6200-2RS?
Sealed units are pre-greased for life; for food or pharmaceutical duty order (or re-grease before service) with an NSF H1 registered food-grade grease.
Are W stainless bearings waterproof?
No — the stainless rings resist moisture and weak chemicals far better than 52100 chrome steel, but salt spray, strong chlorides and unlubricated washdown duty can still corrode W6200-2RS; add seals and food-grade grease for wet positions.
