Needle Thrust Bearing Roller and Its Uses



Needle thrust roller bearings are form-stable type cage fitted bearings that reliably can retain and guide the huge amount of roller needles. Heavy load on an axis and loads by shocks are assembled with these bearings with a small deviation in diameter.


The roller has slightly relieved ends that help to modify the line of contact with the rollers and the raceways. Thus the service life of a bearing is extended by preventing peak stress at the roller ends.


Uses:
1. Needle thrust bearing roller provides stiffness to a great degree in a nominal space on axis. It is used where the adjacent faces of machinery components are meant to serve raceways it takes as less space a thrust washer.
2. They give higher load taking capacity and superior characteristics towards friction.
3. Separate such bearing can be assembled to when surfaces side by side can’t be hardened to the desired level of hardness.


Characteristics:
High capacity to take load compared to single row ball bearing
Rigid and larger shafts can be handled
Good rolling feature as it has a small cross-section
Low Cost


Needle Bearing Catalogue:
Needle bearing catalogue is a list that offers a wide range of needle roller bearing variety and its components. It consists of information on bearing like dimensional know how, recommendation on mounting, speed limits, ratings for loads that will come helpful for the users.


It contains Technical Data providing answers to the important question on designing and calculations on the bearing. There are two types of catalogs available for INA linear motion bearing and INA Metric Needle Roller bearings.


Taper Roller Bearing Design:
Taper roller bearing design is the design based on Tapered Roller Bearing which accommodates huge axial load and is designed to take sufficient thrust so that they can sustain radial forces for huge capacity.


They are designed such that they contain four components- a) Cone, b) Cup, c) Tapered Rollers and d) Cage that retain the rollers.


From this article, hope you got an idea  on needle thrust bearing roller used the friction torque effect to analyze the types of needle roller thrust bearing to be a single row, double row, and triple row.
