We Provide All Kinds of National Needle Bearing

  Open stamped outer ring needle roller bearings, closed stamped outer ring needle roller bearings, inner ring needle roller bearings, and needle roller bearings without inner ring or cage, as well as needle roller bearings with and without cage.
  Stamped outer ring national needle bearing are needle roller bearings with thin stamped outer rings. Its main feature is a low cross-sectional height and high load-bearing capacity. Mainly used for bearing configurations that are compact in structure, cheap in price, and cannot be used as raceway components for needle roller cages. The bearings and bearing housings must be installed in an interference fit manner. If axial positioning functions such as shoulder and stop ring can be omitted, then the bore inside the bearing box can be made extremely simple and economical. The stamped outer ring needle roller bearings installed at the shaft end have double-sided open type and single-sided closed type. The base end face of the closed stamped outer ring can withstand relatively small axial guiding forces. Stamped outer ring needle roller bearings generally do not come with an inner ring. In situations where the shaft neck cannot be hardened or ground, the inner ring listed in the table can be used. The quenched steel plate outer ring of the stamped outer ring needle roller bearing cannot be separated from the needle roller holder assembly. The free space for storing lubricants can extend the interval for replenishing lubrication. Bearings generally adopt a single row design.

  A solid ring national needle bearing is composed of one or two rings and a needle roller assembly with a cage. According to different application scenarios, bearings can be divided into those with inner rings or those without inner rings. Therefore, solid ring needle roller bearings can meet the requirements of light weight, small space occupation, and high power transmission.

  Combination national needle bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components. It has a compact structure, small volume, high rotational accuracy, and can withstand high radial loads while also bearing certain axial loads. And the product structure is diverse, adaptable, and easy to install. Combination needle roller bearings are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery, and printing machinery, and can make the mechanical system design very compact and agile.
