2.Description:
Needle roller and cage assemblies are ready-to-mount, self-contained bearing components. They are an excellent choice for applications that require a very rigid bearing arrangement as well as a high load carrying capacity. If the shaft and housing bore can serve as raceways, needle roller and cage assemblies require minimal radial space.

3.Basic Design:
The needle roller bearings are roller bearings with cylindrical rollers that are long and thin in relation to their diameter.In spite of their low cross section ,needle roller bearings have a high load carrying capacity and are therefore extremely suitabale for bearing arrangements where radial space is limited.

4.Characteristics and uses needle roller bearings:
With thin and long needle bearing roller (roller length of 3 to 10 times the diameter of a diameter of generally not more than 5mm), so the radial structure is compact, the diameter size and payload capacity the same with other types of bearings, minimum diameter, especially for radial bearing mounting dimensions restricted results. Depending on different occasions, the choice of the bearing without inner ring or needle roller and cage assemblies, this time to match the journal and the bearing surface and shell holes, as bearing directly on the surface, the outer rolling surface, in order to ensure the load capacity and operational performance and a ring bearing the same shaft or housing bore raceway surface hardness, machining accuracy and surface quality should be similar roller bearing rings. Such bearings can only bear radial load.

4.Applications:
 In addition to catalogs listed in the bearing can be used for general engineering, such as: open type Needle roller bearings (1), closed Needle roller bearings (2), needle roller bearings with inner ring (3) and non-Needle roller bearing inner ring / no cage needle roller bearings without inner ring (4), a cage and no cage full of needle roller bearings (5) SKF can supply all types of needle roller bearings, 1 needle Cage assembly 2, needle roller bearings without ribs 3, self-aligning roller bearings 4, combined needle roller / ball bearings 5, combined needle roller / thrust ball bearings 6, combined needle roller / cylindrical roller thrust bearings
