The SFRW Series offers the highest level of functionality in a miniature bearing: an integrated flange for positioning, an extended inner ring for spacing, and AISI 440C stainless steel for corrosion resistance. These bearings are the premium choice for medical instruments and food-handling robotics where simplified assembly and hygienic, rust-proof performance are essential.
