IKO RNA6913 Double Row Flat Needle Roller Bearings size 72x90x45mm

Product Introduction:

Needle roller bearings are bearings with cylindrical rollers that are small in diameter relative to their length. The modified roller/raceway profile prevents stress peaks to extend bearing service life.

Supplies needle roller bearings in many different designs, series and in a wide range of sizes, which make them appropriate for a wide variety of operating conditions and applications.

Needle roller bearings are a bearing that is classified as either radial or thrust depending on the direction of the load being supported. Needle roller bearings include bearings whose rollers slightly exceed the size range of needle rollers as stipulated by ISO. Needle roller bearings include drawn cup and solid radial bearings, as well as application-specific cam followers, and roller followers.

Feature:

Needle roller and cage assemblies are single or double row units comprising cages and needle rollers.

Since their radial section is no greater than the diameter of the needle rollers, needle roller and cage assemblies allow bearing arrangements with a very small radial design envelope to be achieved. They have very high load carrying capacity, are suitable for high speeds and can be easily fitted.

If the raceways are produced to high geometrical accuracy, bearing arrangements with high runout accuracy can be achieved.

The radial internal clearance can be influenced by the needle roller sort and by the shaft and housing tolerance.

Needle roller and cage assemblies require a hardened and ground raceway on the shaft and in the housing.

Application:

These bearings are the most common type and are used in a wide variety of applications. Such as Steel Industry , Mining & Construction , Papermaking Machinery , Wind Turbines , Machine Tools , Gearboxes , Electric Motors , Pumps & Compressors , Injection Molding , Motorcycles , Railways, etc.
