111-2412: 30mm Inner Diameter Needle Roller Bearing

A Needle Roller Bearing is a type of roller bearing that uses cylindrical rollers with a small diameter called needles, instead of the larger balls found in other types of bearings. The needles are held in place by a cage or retainer, which keeps them evenly spaced and prevents them from contacting each other. Attributes: • Provided linear contact areas with outer rings to distribute loads on the larger surface area. • Designed to reduce friction and improve efficiency. • Provide high radial stiffness. • Designed to operate in high-temperature environments. Applications: A Needle Roller Bearing is used to prevent direct metal-to-metal contact between two elements that are in relative motion. This prevents friction, heat generation, and ultimately, the wear and tear of parts. It also reduces energy consumption as sliding motion is replaced with low-friction rolling.
