Jinan Kelunte K12*15*8 Needle Roller Bearing Needle Roller and Cage Assemblies Manufacturer
Description of Needle Roller and Cage Bearing:
Needle roller bearings with machined rings made of carbon chromium bearing steel have a low sectional height and a very high load carrying capacity for their size. They may be used with or without an inner ring, depending on the application.
Needle roller bearings without an inner ring (fig 1) are an excellent choice for compact bearing arrangements if the shaft can be hardened and ground. Eliminating the need for a separate inner ring enables a larger shaft diameter and a stiffer arrangement.
Needle roller and cage assemblies have a complement of needle rollers held in place by a cage. With no inner or outer ring, the low cross section provides maximum load-carrying capability within the smallest envelope. The mating shaft and housing are normally used as inner and outer raceways.
The unitized design makes for easy handling and installation. Controlled contour rollers with an optimum profile reduce end stresses and allow operation under moderate misalignment. A variety of cage designs, styles and materials, as well as multiple roller paths and segmented construction, meet broad application requirements.
Size range: 6mm - 150mm bore
