NA4822 Needle Roller Bearing 110x140x30mm Single Row For Hydraulic Motor Pump Rotary Assemblies

• NA4822 is a single row machined ring needle roller bearing complete with separable inner ring, standard dimension 110×140×30 mm. Produced from high toughness GCr15 bearing steel, it adopts stamped steel cage to evenly arrange needle rollers.Equipped with integrated inner ring, it can be directly installed on common shafts without special quenching and grinding treatment, greatly simplifying assembly work. Featuring ultra-small radial section and excellent radial load capacity, it is ideal for heavy-load occasions with limited radial installation space. The open design allows easy grease filling and routine maintenance for long-term stable operation.
