What are the classifications of combined needle roller bearings

View:39301/11/2023  

The so-called combined needle roller bearing refers to the bearing composed of needle roller bearing and other types of bearings. According to the difference of the combined bearing, the combined needle roller bearing is divided into NKX type, NKXR type, NKIA type, NKIB type, AXN type and ARN type. Let the manufacturers of combined needle roller bearings introduce these classifications in detail.

NKX type combined needle roller bearing: needle roller bearing bears radial load, thrust ball bearing bears axial load, suitable for bearing light axial load, and can rotate at high speed. Common codes such as NKX20T2Z, where T2 represents resin cage, Z represents with dust cover, and if there is no afterwear, it is iron cage.

NKXR type combined needle bearing: NKXR type is basically the same as NKX type, the ball is replaced with roller, which can bear higher axial load, and the post-code is the same as NKX type.

NKIA type combined needle roller bearing: the combined bearing composed of needle roller bearing and angular contact ball bearing can bear the unidirectional axial load determined by angular contact ball bearing, and is suitable for high-speed rotation and light load scenarios.

NKIB type combined needle roller bearing: a combined bearing composed of needle roller bearing and three-point contact ball bearing, with the same application range as NKIA type, and can bear two-way axial load.

AXN type combined needle roller bearing: the combined bearing of needle roller bearing and bi-directional thrust needle roller, which is a support bearing for precision ball screw, can bear bi-directional axial load.

ARN type combined needle roller bearing: basically the same as AXN type, but in comparison, ARN type has higher axial bearing capacity.

The above is about the classification of combined needle roller bearings. Zhihua is combined needle roller bearings manufacturer from china. We have many years of experience in producing and selling combined needle roller bearings. At present, our combined needle roller bearings are not only of good quality but also of relatively low price. If there is any need, welcome to consult!
