Needle cage -
Needle Roller Cages are bearings which present an enhanced rotational performance. These can accurately integrate and retain needle rollers with small dimensional variations in precisely shaped cages. These cages are responsible for accurately guiding the needle rollers.The cages are effective for use in small spaces when combined with shafts and housing bores that are heat-treated and ground as raceway surfaces. They can also withstand harsh operation conditions such as high speed rotation and shock load. This is due to the lightweight design, high rigidity, and large lubricant holding capacity of the cages.
