Needle Roller Bearing Cam Follower Bearing CF20 KR47 Bearing
Needle Bearing
Needle bearing is a roller bearing with a cylindrical roller, which is thin and long relative to its diameter.This roller is called a needle roller.Although has a small cross-section, bearing still has high load capacity, needle bearing with fine and long roller (roller diameter D 5 mm or less, acuity 2.5 L/D, L) for the roller length, so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.
Type
(1) closed punching outer ring needle roller bearing(
(2) needle roller bearing with inner ring
(3) needle roller bearing without inner ring/needle bearing without inner ring without retaining frame
(4) full needle roller bearing with and without a cage
(5) They also can supply various types of needle roller bearing, 1, 2 needle cage components, no guard the needle roller bearing 3, can make 4, combined needle roller / 5, combined needle roller bearing/thrust ball bearings
(6) Combined needle/cylinder roller thrust bearing.
Advantages
Needle bearing with fine and long roller (3 ~ 10 times the diameter of the roller length is, no more than 5 mm in diameter), so the radial structure is compact, its diameter and load capacity at the same time, with other types of bearing outside diameter to a minimum, especially suitable for the limited size of the radial installation supporting structure.The processing precision and surface quality of needle roller bearing should be combined with bearing sleeve and application according to different usage.Needle roller bearing is a bearing unit composed of a core needle bearing and a thrust bearing component.
