The D/W Series (Plain) includes high-precision, non-flanged stainless steel bearings following imperial standards. These bearings are designed for standard cylindrical housings where a flange is not required. They offer smooth, low-torque rotation and are frequently used in high-speed fans, HDD spindles, and various electronic precision devices.
