How the W607-2RS model number is decoded
The W prefix denotes SKF stainless steel deep-groove bearings (X108CrMo17 / AISI 440C class rings). In the 6000-series, the final digit is the bore in millimetres: 607 fits a 7 mm shaft (direct-number miniature spelling). Envelope 7×19×6 mm (0.276×0.748×0.236 in), C 1.53 kN, C0 0.585 kN, Pu 0.025 kN; limiting speed 24000 r/min and mass 7.25 g. SKF catalogues the sealed execution as W 607-2RS1: 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
- bicycle and outdoor equipment
- appliances exposed to moisture
- food and beverage conveyors
- pharmaceutical and packaging machines
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
- 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
- The stainless steel is martensitic and MAGNETIC; do not reject W607-2RS 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: W607-2RS is quoted at C 1.53 kN versus the 6 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 W607-2RS; standard fill is industrial grease unless specified otherwise.
- Corrosion resistance depends on clean, undamaged surfaces: never weld near W607-2RS or scratch the raceways during mounting, since the damaged spot starts corrosion.
- Assign interference to the rotating ring: on a conventional shaft-mounted 7 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.
- Mount by heating the inner ring (max 120 °C) — driving W607-2RS home through the outer ring or balls brinells the raceways.
Frequently asked questions
What are the dimensions of the stainless W607-2RS?
SKF W 607-2RS1 measures 7×19×6 mm (0.276×0.748×0.236 in), about 7.25 g, C 1.53 kN.
What does the W in W 607-2RS1 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.
Where is W607-2RS typically used?
Food and packaging machines, pharmaceutical equipment, washdown conveyors, chemical and marine-atmosphere drives and appliances exposed to moisture.
What grease is supplied in W607-2RS?
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.
