The SFR Series combines the axial locating advantages of a flanged outer ring with the superior corrosion resistance of AISI 440C stainless steel. These inch-series bearings are specifically engineered for use in environments exposed to moisture, mild chemicals, or sterilization processes. They are widely utilized in medical devices, dental handpieces, and marine navigational equipment where both precision and rust prevention are critical.
