What does a needle bearing do?

People also ask what a needle thrust bearing is.

Thrust Bearings & Washers Needle thrust bearings can be used when high axial loads are required and the envelope space is limited. These bearings are made up of a machined or stamped cage and rollers. Thrust washers act as raceways and are paired with the cage that holds the rollers.

What is a drawn cup bearing? Complete bearing units, called drawn cup needle roller bearings, consist of a thin-walled outer cup with a drawn needle and a roller. They can be ordered in full complement or as a cage assembly. Caged bearings have fewer rollers, which reduces friction and allows for higher speeds.

Do Needle Bearings require grease?

Grease is the most common lubricant for needle bearings, but oil or oil mist lubrication are preferred for high-speed or heavy-duty applications. While many bearings are light-duty, they don't require relubrication. However, high loads and speeds may call for it.

What's the purpose of needle bearing?

A needle roller bearing uses small cylindrical rollers. These rollers are used for reducing friction on a rotating surface. Needle roller bearings are larger than ball bearings because they have a greater surface area in contact with the bearing raceway journals.
