Needle roller bearing overview:
They are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle bearing have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.
Equipments:CNC Lathe,CNC Vertical Machining Center,CNC Horizontal Machining Center,Radial Drilling machine,Millingmachine,Turning Lathe,Boring machine,Gantry Machining Center,Surface Grinding Machine,Internal Grinding Machine and so on.
Quality control:In house,coming inspection,first off,spot check in processing ,final inspection, 100% inspection for critical dimension.

Main Market: | North & south America, European countries, Middle East |
Delivery Time: | 20-30 days After order confirmation |
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 |
Introduction
Needle roller bearing is a kind of roller bearing with cylindrical rollers, about its diameter, rollers are slim and long, this kind of rollers called needle rollers.
Application feilds
It is widely used in machine tools, metallurgical machinery, textile machinery, printing machinery and other mechanical equipment.
