Needle Roller Bearings

Available462 products

Needle roller bearings have a thin profile for applications where the radial space is limited. These small-diameter cylindrical rollers support high radial loads and high speed applications.

Drawn-Cup Needle Roller Bearings

These drawn-cup needle roller bearings have an outer cup, or shell, that serves as the outer ring raceway. The cup is drawn from a strip of steel and case-hardened. These bearings support radial loads with reduced friction. They are often used in steering systems and drive-lines for automotive applications.

Heavy-Duty Needle Roller Bearings

These heavy-duty needle roller bearings have a thicker outer shell that serves as the outer-ring raceway for high-load capacity and shock resistance. The outer ring is machined with an oil channel for consistent lubrication from an oil port in the bearing's housing. These heavy-duty bearings are used in demanding applications such as industrial machinery and wind power generation.

Single-Direction Needle Roller Clutch & Bearing Assemblies

These needle roller bearings include a clutch in the assembly that move the bearing in a single direction. Their outer shell, or cup, serves as the outer-ring raceway. The cup is drawn from a strip of steel and case-hardened. These bearing and clutch assemblies are often used in conveyor applications that require movement in only one direction.

Needle Roller Bearing Inner Rings

These rings fit a needle roller bearing to provide an inner raceway for the bearing. They are useful for applications that have an unhardened shaft, or when the internal bearing components need more protection from dirt and dust. Inner rings should be matched to a compatible needle roller bearing.
