Product Description Product DescriptionNA/RNA/NK series 16X24X13mm radial needle roller bearing RNA4901 for riveting machineryA part of our products: Pictures showDrawingDescriptionsNeedle roller bearing is a bearing unit composed of machined outer ring & inner ring,cage and needle roller assembly featuring small section height,big load capacity & rigidity,compact structure and small size,high rotating accuracy with the structure of disposed inner ring. Needle roller bearing is characterized by multiple structures,broad adaptability and easy installation. It is widely used in automobile,machine toll,lathe,metallurgical,textile,printing industry and etc. Various machinery equipment. With this kind of bearing,machine design can realize the goal of small-scale & light weight. Types of Designs: This kind of bearing has multiple structural styles for the choice of customers,such as narrow & broad series,with or without inner rings,cages,rib or sealings. It can be designed according to the special structural requirements of customers as well. Product Precision Accuracy: Dimensional tolerance and geometrical accuracy is based on GB/T5801.Mutual difference of needle roller diameter is 2 um,and the precision grade is class G2(ISO GB/T309)The diameter of inscribed circle conforms to tolerance grade F6 before the fitting of outer ring with cage and roller assembly.Bearing radial running clearance conforms to the value defined by class 0 group of GB/T4604Special precision grade in based on GB/T307.1For fuller information on the special requirement of bearing running clearance, inscribed circle and precision grade,please contact our company. Material: Material for needle roller is GCr15 bearing steel,quench-hardening HRC60-65Material for inner and outer rings is GCr15 bearing steel,quench-hardening HRC60-65Material for cages is quality low-carbon steel or reinforced nylon. Special Directions: Bearing running clearance and inner-cutting roundness should be regulated according to different conditions. Machine tolls should be used for press-in fitting or thermal fitting when install the bearing.Limited by plastic cages(suffixed with TN) and sealing-element material ,operating temperatureis -30--+100 For general-disposition design of bearings,refer to the relevant recommendation in the applied technology of roller bearings.
