Product Description

CHIK NA4908 NA4909 NA4910 NA4911 NA4912 NA4913 NA4914 NA4915 Needle Roller Bearings 
Features: 
Compared to ball b earings  and ordinary roller bearings, needle bearings havea greater surface area in contact with the races, so they can support a greaterload.  They are also thinner, so they require less clearance between the axleand the surrounding structure.

Classification:

1	Drawn Cup Needle Bearing	HK, BK
2	Needle Bearing with Inner Ring	NA, NKI
3	Needle Bearing without Inner Ring	NK, RNA
4	Full Complement Needle Bearing	NAV
5	Radial Needle Roller and Cage Assemblies	K, KK
6	Thrust Needle Roller and Cage Assemblies	AXK, AS

Applications: 
Needle bearings are heavily used in automobile components such as rocker arm pivots, pumps, compressors, and transmissions. The drive shaft of arear-wheel drive vehicle typically has at least eight needle bearings (four ineach U joint) and often more if it is particularly long, or operates on steepslopes.
