What are Needle Bearings?
A needle bearing is a type of rolling-element bearing that utilizes slender, cylindrical rollers known as needles. These needles are arranged radially around a central raceway, with a cage separating them to ensure smooth operation. Due to their unique design, needle bearings offer a compact and high-capacity solution for applications with limited space.
