Needle Roller Bearings NA49 For Vibrating Machine

Category:

Description

Needle bearings are a small cylindrical type of roller bearings which are used to prevent friction between moving surfaces which have low rotational speeds.

Cage Type
Features
CC
It consists of two pressed steel cages, flangeless inner ring and guide ring centred on the inner ring, It adopts symmetrical spherical roller,which bear the larger load , longer life compared with CA
CA
It consists of one piece of machined brass cage,one inner ring with double flanges and one guide ring centred on the inner ring.The limit speed is higher,and have a relatively small noise.
MB
It consists of two piece of machined brass cage,one inner ring with double flanges and one guide ring centred on the inner ring.its performance and characteristics are similar to CA, but load rating is lower.
E
It is the latest design, using symmetric spherical roller, two piece of pressed steel cages ,flangeless inner ring and guide ring centred on the cage,Guide ring around the outer can improve lubricating condition on roller face of end.It can also reduce friction,help guiding roller in the nonload region,and assist roller into the loading area,meanwhile,the length of roller is getting longer so that the load ratde has been enhanced. Usually rated load can be increased by 20% -35%.
