INA type of needle roller bearing:
HK, BK, NK, NKS, NA, RNS, NAO, RNAO, NKI, NKIS series and so on.
IKO type of needle roller bearings:
NA, RNA, TAF, TR, BR, KT…EG, KTV…EG series and so on.
Application:
This kind of bearings is widely used in areas of auto, motor, electric bicycle, electric tool, thread spinner, agricultural machinery, industrial sewing machine, construction machinery and so on.
Features:
Needle roller bearings is a kind of bearings with low cross section which have a high load carrying capacity, thus is extremely suitable for the bearing arrangement where radial space is limited. That is to say, this kind of bearings has lower height of cross section and higher carrying capacity. Common needle holding bearings have excellent performance during high rotation speed, its needle rollers is leaded by high rigidity and high precision retainers with very low error of size. It’s especially suitable to used in limited space, moreover, because of its features of rather high capacity of lubrication, gently weight and high rigidity, it also have very wide usage, even in such special situation with high requirement, such as high rotation speed, high impacting load.
