HK2020 needle bearing feature:

 

(1) Drawn cup needle roller bearing is by a stamping outer thin wall with a needle roller and cage component complete composition unit;

 

(2) Has the special save space structure;

 

(3) Set with hardening is used in IR or LR series inner ring combination;

 

(4) Double drawn cup needle roller bearing can have oil hole as standard characteristic;

 

(5) But with AXW series thrust needle roller composition combined with use;

 

(6) Sealing the mouth drawn cup needle roller bearing used in closed bearing parts of the shaft end, so it can prevent the damage caused by shaft, avoid moisture and pollution.
