needle roller bearings are a type of roller bearing that uses long, thin cylindrical rollers instead of spherical or tapered rollers. The rollers have a high length to diameter ratio, which allows them to carry high radial loads while maintaining a small profile.

needle rollers are held in place by a cage or retainer, which maintains a uniform spacing between the rollers and prevents them from contacting each other. the cage is typically made of steel, plastic, or brass. needle roller bearings are commonly used in applications where high radial load capacity is required, but the available space is limited. they are used in a wide range of applications.
