SFR2 2rs Bearing Product Overview & Core Advantages
The SFR2 2RS is a sealed miniature ball bearing designed for precision applications requiring reliable performance in compact spaces. This single row deep groove ball bearing excels in handling radial loads while offering protection against contamination. Manufactured entirely from stainless steel with nitrile rubber seals, it provides excellent corrosion resistance and is pre-lubricated for immediate use. Its compact design (0.125" bore, 0.375" OD) makes it ideal for applications where space is limited but high reliability is essential.
