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. Quotations for non-magnetic versions are available upon request.
