FR1-5 2rs Bearing Product Overview & Core Advantages
The FR1-5 2RS is a miniature sealed ball bearing designed for precision applications requiring compact dimensions and reliable performance. This inch series bearing features a single row construction with integral rubber seals (2RS), providing effective protection against contamination. Engineered to handle radial loads primarily, it offers excellent performance in confined spaces while maintaining ABEC1 precision class tolerances. The combination of chrome steel components and stainless steel cage ensures durability and consistent operation across a wide temperature range from -86 to 230 °F.
