Needle rollers are the load-carrying component of the bearing, and are the one common component of all needle roller bearing types. These allow the outer and inner rings to rotate almost friction-free. They are most frequently manufactured from a steel alloy.

Raceways (if present) serve to guide the rollers within the bearing. These items are commonly manufactured from carbon chromium steel or other alloys to improve hardness, fatigue resistance, and dimensional stability.

Bearing cages separate rollers to keep the load evenly distributed around the bearing. They also reduce bearing noise, improve rolling conditions, and prevent sliding. Additionally, they contain rollers within a single assembly. Steel is the most commonly used cage material in needle roller bearings. Plastic cages can be used where operating conditions permit. Lubrication and surface treatments can reduce the amount of heat generated from friction. Some drawn cup needle roller bearings are designed without a cage, and contain a full complement of needle rollers.
