A stainless steel bearing can be used “dry” or without any lubrication. Chrome steel bearings rely on a protective film of oil to prevent corrosion. This oil film is not required by stainless steel bearings.
Unlubricated stainless steel bearings should only be used at extremely low speeds. This is because lubrication reduces friction and prevents excessive heat build-up where metal to metal contact occurs. An unlubricated bearing will run much hotter at anything other than very low speed, leading to more rapid wear.
