NKI 80/35 Needle roller bearings without inner rings NKI80/35 80x110x35mm mechanical component bearing NKI series
Needle Roller Bearings Information
| 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 |
