RNA,NK,NA,NKI,Solid collar needle roller bearing with high speed,With&Without Inner Ring
needle roller bearing without inner ring.
Needle Roller Bearings have a high load carrying capacity and can
operate at high speeds. They have slim design and are suited where
radial space is limited. They are available with or without an
inner ring.
Needle roller bearings with inner rings are used if the shaft
cannot be used as a raceway.
Drawings and parameters:
No inner ring solid ferrule needle bearing RNA, NK series.
