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.

Needle roller bearings without inner ring include NK, NKS, RNA49, RNA69, RNAO series. The rolling needles roll directory on the quenched and ground shaft. The needle bearings without inner ring are compact in structure. The rotating precision will be increased if the shaft is machined with high precision.
