Needle roller bearing is the roller bearing with cylindrical roller.The roller is thin and long compared with the diameter.This type of roller is called needle roller.Although it has a small section,the bearing stil has high load bearing ability. Therefore,it is especially suitable for occasion where the radial space is limited.
The contour surface slightly contract at the place near the end.The correction of contact between needle roller and raceway can avoid the destructive edge stress.
The types of bearing only bear radical load.
