GQZ 30314D Single Row Tapered Roller Bearing 70×150×35mm Separable Assembly For Combined Load Transmission Shafts
30314D is single row separable tapered roller bearing of 303 series with strengthened D structure design. Its conical roller and raceway contact surface can simultaneously bear large radial load and unidirectional axial load. The separable cone assembly and cup simplify installation and preload adjustment, suitable for power transmission shafts under mixed radial-axial load conditions.
