How the W6202-2RS 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 02 follows the 10/12/15/17 mm exception table, so 6202 fits a 15 mm shaft. Envelope 15×35×11 mm (0.591×1.378×0.433 in), C 6.37 kN, C0 3.6 kN, Pu 0.156 kN; limiting speed 13000 r/min and mass 44 g. SKF catalogues the sealed execution as W 6202-2RS1: 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
- small pumps handling corrosive media
- bicycle and outdoor equipment
- appliances exposed to moisture
- food and beverage conveyors
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
- Stainless bearings carry lower load ratings than chrome steel of the same envelope: W6202-2RS is quoted at C 6.37 kN versus the 11 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 W6202-2RS; standard fill is industrial grease unless specified otherwise.
- Corrosion resistance depends on clean, undamaged surfaces: never weld near W6202-2RS or scratch the raceways during mounting, since the damaged spot starts corrosion.
- Temperatures above roughly 300 °C temper the stainless races; even standard greases fail far earlier — keep W6202-2RS inside the quoted grease temperature range.
- Assign interference to the rotating ring: on a conventional shaft-mounted 15 mm position the inner ring rotates, so use a k5/m6 shaft seat with an H7 housing — reverse the logic if the outer ring rotates.
- Clearance suffixes follow the seal code in the designation stack (e.g. W 6202-2Z/C3 in SKF spelling); no suffix means normal CN internal clearance.
Frequently asked questions
What are the dimensions of the stainless W6202-2RS?
SKF W 6202-2RS1 measures 15×35×11 mm (0.591×1.378×0.433 in), about 44 g, C 6.37 kN.
What does the W in W 6202-2RS1 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.
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.
Where is W6202-2RS typically used?
Food and packaging machines, pharmaceutical equipment, washdown conveyors, chemical and marine-atmosphere drives and appliances exposed to moisture.
