SR2-5 2rs Bearing Product Overview & Core Advantages
The SR2-5 2RS is a sealed single row deep groove ball bearing designed for reliable performance in demanding applications. Engineered with stainless steel construction throughout its rings, balls, and cage, it offers excellent corrosion resistance. Its compact design, featuring a 0.125" bore and 0.3125" outside diameter, provides a space-saving solution. The key advantage of this bearing is its 2RS dual rubber seals, which effectively retain lubrication and exclude contaminants, ensuring long service life and maintenance-free operation in a wide temperature range from -86 to 230 °F.
