 Needle Bearing 2020 Needle Roller Bearing HK2020  

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;

(7) 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.
