What’s the features of k type needle bearing?

There are many types of bearings. Different bearings have different characteristics. What are the characteristics of k type needle bearing? Can accept higher radial load, higher speed, can not accept axial load, higher rigidity.

The general surface of the needle roller is slightly shortened at the proximal surface. The results of the needle roller and raceway line touch correction can be k type needle bearing to prevent destructive marginal stress. The k type needle bearing of the support roller is a thick-walled outer ring, which is quenched by high temperature and high nitrogen. The high-precision sorted rollers are guided by the ribs of the high-rigidity outer ring. With linear touch, the roller can be easily transformed directly on the raceway Accept huge loads. In order to remove the stress, the outer ring of the supporting roller is drawn with a curved surface. The curved roller has various specifications with single and double sealing rings, without sealing ring, with sealing ring and other specifications.

The k type needle bearing is equipped with thin and long rollers, the length of the roller is three to ten times the diameter, and the diameter is usually not more than 5mm, so the radial layout is compact, and the inner diameter scale and load can be the same as other types of bearings. most. Depending on the application, the bearing or needle roller and cage assembly without inner ring can be used. At this moment, the appearance of the journal matched with the bearing and the appearance of the housing hole are directly used as the inner and outer rolling appearance of the k type needle bearing, in order to ensure the load capacity and working performance. Like the bearing with ring, the hardness, processing accuracy and appearance quality of the shaft or shell hole raceway should be similar to the raceway of the bearing ring. Such k type needle bearing can only accept radial loads.

The types of k type needle bearing, in addition to those listed in the catalog, can be used for bearings in general engineering, such as: open drawn cup needle roller bearings. Cage-filled needle roller bearings with and without cages, closed-end stamped outer ring needle roller bearings, and k type needle bearing without inner ring / needle roller bearings without inner ring without cage, needle roller bearings with inner ring, also available Various types of needle roller bearings.

k type needle bearing without ribs, combined needle roller / ball bearings, needle roller cage assemblies, self-aligning needle roller bearings, combined needle roller / thrust ball bearings. Combined needle roller / cylindrical roller thrust bearings, drawn cup needle roller bearings. Drawn cup needle roller bearings are needle roller bearings with a thin stamped outer ring. Its first characteristic is that the cross-sectional height is very low and the load can be high. It is mainly used for bearing equipment with compact layout and low price, and the inner hole of the bearing box cannot be used as the raceway of the needle roller cage assembly.

The combined needle roller bearing is a bearing unit composed of a radial needle roller bearing and a thrust bearing component, and its layout is compact and compact. Moreover, the product layout has various forms, wide adaptability and easy installation. Combined k type needle bearing are widely used in various mechanical equipment such as machine tools, metallurgical machinery, textile machinery and printing machinery, and can make the mechanical system described very compact and flexible.
