What are needle bearings good for?

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

Are needle bearings better than ball bearings?

A needle roller bearing is thus able to withstand 2 to 8 times more load than ball bearings or cylindrical roller bearings of the same shaft diameter, all this in a small space.

Are needle roller bearings better?

Essentially, needle roller bearings have: Higher load capacity than single-row ball or roller bearings of comparable OD. The ability to handle a larger, more rigid shaft in a given application. Excellent rolling characteristics within a small cross section.

What is meant by needle bearing?

Definition of needle bearing : a roller bearing with very slender rollers varying typically from 0.08 to 0.16 inch in diameter.

How do you lubricate a needle bearing?

Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty bearings never require relubrication, but high loads or speeds demand it.

What does false Brinelling lead to?

False brinelling is a bearing damage caused by fretting, with or without corrosion, that causes imprints that look similar to brinelling, but are caused by a different mechanism. False brinelling may occur in bearings which act under small oscillations or vibrations.

What is a Conrad bearing?
