Needle Roller Bearings
Needle roller bearings sometimes called needle bearings use long and narrow cylindrical rollers that sometimes exceed JIS/ISO size ranges. They are categorized as thrust or radial bearings based on which load direction they support. Radial types include drawn-cup and solid types, as well as application-specific track rollers Thrust needle and thrust roller bearings respond to axial load needs
Typical Structure
There are four main types of needle roller bearings, including caged roller, drawn cup, precision race and thrust roller. Their typical structure includes an inner race or just a shaft, a cage to contain the needle rollers and an outer raceway. Selecting the correct type of needle roller bearing for your particular application depends on a variety of factors such as the necessary load capacity, load type and speed, as well as the expected temperature limits, lubrication requirements and service life.

Application
Needle roller bearings are most commonly used in automobile, agricultural and construction components, including compressors, transmissions, gearboxes, pumps, torque converters, suspensions, U-joints and rocker-arm pivots. They’re also found in domestic appliances such as portable power tools, pump clutches and spindles
