Stainless steel truck needle bearing NAV4009

Overview of  truck needle bearing NAV4009

Drawn cup needle roller bearings support radial loads and reduce friction between rotating components, with a drawn outer shell serving as a raceway for the rollers. The low cross section of the drawn cup bearing provides high load-carrying capability with minimum required space. Drawn cup bearings are easily installed with a press fit in the housing.

Needle roller bearings 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.

As for the full complement needle roller bearing with inner ring, the outer ring has the oil hole. The lubricating oil can be fed in from the oil hole. The outer ring has the double shoulders. As for the full complement needle roller bearing without inner ring, since the inner ring has no shoulder and cage, the inner ring, outer ring, complete set of needles can be mounted respectively. It is s suitable for parts of which the radial size is limited.
The surface of shaft journal fitted with it is acted directly as rolling surface. It is requested that the surface hardness be no less than HRC60, surface roughness, no more than 0.63μm. This kind of full complement bearing, with inner ring or without inner ring, does not limit the axial shift of shaft and housing.

Advantages of  truck needle bearing NAV4009

- Smaller cross-section leading to greated rigidity,higher load-carrying capacity & lower inertia of the needle roller bearings help size and weight reductions in machinery.

- Though they are less wide,their load carrying capacity is high and is most suitable for applications where the load is high & the radial space is less.

- Needle roller bearings,which are designed to withstand oscillation can operate under severe conditions & interchange with sliding bearings

Physical Characteristic of truck needle bearing NAV4009

	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
