Needle rollers have a high length-to-diameter ratio, which allows them to have a larger contact area with the raceway, providing more surface for load-bearing and reducing friction between two surfaces. Needle rollers are commonly made from high-quality steel or another durable material and are often used in applications where space is limited, and high load-carrying capability is required.
