SHAPE LOCATION TOLERANCE SHOULD BE TO CURRENT STANDARD;
Outer ring for drawn cup needle roller bearings(DC type) is made of cold rolled steel strip accurately formed.Structure of DC needle roller bearings features space saving and higher capacity.They are suitable for applications with limited space and housing not hard enough to act as raceway. No requirement on axial location when the DC needle roller bearing is pressed into the housing.
We can offer almost types of linear bearings (LM,LME,LMF,LMH,LMK,KH,etc)Size range is from ID6-60mm Linear
motion bearings have the characterized of smooth movement,low friction,high rigidity and long life span,economical and easy to maintain or replace
Applications:Widely used in the defense,precision machinery,medical instrument,chemical,printing,agriculture,robotic,automatic production line etc
our top mission is 100% quality control and 100% customer satisfied. we are responsible to assist our customer to be competitive and advantaged in the market.
