Needle roller bearings are small in sectional height, therefore useful in making machinery smaller and lighter. This type of bearing is used in a wide range of machinery, such as automobiles, motor cycles, electric machines, machine tools, aerospace and office equipment.

Needle roller bearings are compact, highly rigid and superior in load carrying performance, compared with other types of bearings. Excellent for carrying oscillating loads; contains many small diameter rollers.

Widely employed in stud type and yoke type track rollers used as guide rollers in cam mechanisms or linear motion units.

Also used in miniature one-way clutches in the clutch mechanisms of office equipment, such as copying machines.
