Product Description

Engeering Machinery Bearing Needle Roller Bearing NA4844 NA4848 NA4852 NA4856 NA4860 NA4864 NA4868 NA4872  

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.









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.
