2 .  Product Description
 

Needle roller bearing NA4872

 

Needle roller bearing NA4872 are roller bearings with cylindrical rollers that are small in diameter . In spite of their low cross section , needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited .

 

Needle roller bearing NA4872 have a high load carrying capacity in addition to their low cross-section and stiffness . They are especially suitable for bearing arrangements where radial space is limited . Because needle roller bearing NA4872 only carry pure radial load and can not limit the axial displacement of shaft relative to the housing . It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings .

 

 

 

 3 .  Needle Roller Bearings Information

 

Material: GCr15, 
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
