SFRW166 Bearing Structural Features & Performance Benefits
This bearing's performance is derived from its optimized single row construction. The deep groove raceway enables efficient handling of radial loads and moderate axial loads in both directions. The use of stainless steel for all critical components ensures high corrosion resistance, making it suitable for harsh environments. The MC3 radial internal clearance provides optimal operational fit for many standard applications. With a limiting speed of 45,000 rpm, it is capable of high-speed operation when properly lubricated. The extended inner ring enhances mounting stability and simplifies assembly.
