The Original Japan IKO needle roller bearing RNA4904

Material:  

GCr15,GCr15 SiMn , G20Cr2Ni4A

Bore Size:  

10mm-30mm & Special diameter Upon the customers' request

Main Market: 

North & south America, European countries, Middle East

Physical Characteristics:

1)   needle bearing can be separated by single row.

2) This kind of bearing can be submitted to high radial load and some axial load.

3) The rolling element of needle roller bearing is needle,the two ends of the external lines have the corrective slope which can eliminate the contact stress.

4) Moreover, we can manufacture these bearings according to customer's drawings and samples
