Needle Roller Bearings
Needle roller bearings are specialized for high radial loads, minimal friction, and space efficiency. They consist of small, cylindrical needle rollers held together by a cage or retainer, distributing loads evenly across a large surface area. Commonly used in automotive transmissions, machine tools, and industrial equipment, needle roller bearings are available in various designs, including drawn cup, solid, and inner rings. Selection depends on load capacity, rotational speed, and operating conditions.
