SFR1-5 2rs Bearing Product Overview & Core Advantages
The SFR1-5 2RS is a single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. This inch-series bearing features a sealed construction with stainless steel components throughout, providing excellent corrosion resistance and durability. Its primary advantage lies in its ability to handle radial loads efficiently while operating within a wide temperature range of -86 to 230 °F. The integrated nitrile rubber seals (2RS) ensure contaminant exclusion and lubricant retention, making it ideal for applications where maintenance access is limited.
