SF689ZZW6 Budget Metal Shielded Stainless Steel Flanged Deep Groove Ball Bearing 9x17x6mm

Stainless Steel Metal Shielded Flanged Deep Groove Ball Bearings: Manufactured to the same principal sizes in stainless steel as standard chrome steel bearings and fitted with metal shields, these bearings have an additional flange to allow fitting into housings flush against the shoulder of the flange. They are often used on steel tracks as guides and supports. The shields serve to offer protection to prevent ingress of debris and dust whilst retaining the grease within the bearing
Benefits: Cost effective replacement bearing, Flanged design, Metal shielded, Higher corrosion resistance
Note: These bearings will eventually corrode in a marine environment and it is recommended to completely cover with grease or similar protection where practical. Due to the material requirements of these bearings to have a hard-wearing construction, they will be made of a harder form of Stainless Steel, such as 440 or similar, which will be attracted by magnets.
