Product Description

KOMEL needle roller bearings are highly efficient and are a type of roller consisting of a single needle, a support frame, an inner ring and an outer ring. Sometimes designs without an inner or outer ring are also available.

Needle roller bearings have a large length-to-diameter ratio. Typically, the diameter is less than 5 mm and the length is several times the diameter. This method allows the needle roller bearing to accommodate more rotating parts than other types of bearings with the same radius, and therefore has a higher load capacity. At the same time, the contact area between the needle rollers is small and the friction coefficient is low, so the rotation is smooth.

They are widely used in industries such as automobiles, industrial machinery, aircraft, medical equipment and housing.

Application

Automotive Industry: Widely used in vehicle transmissions, clutches, and engines. In transmissions, needle roller bearings support synchronizers and gear shafts, handling radial and axial loads for smooth operation and precise shifting. In clutches, they support the clutch shaft, enabling rapid engagement and disengagement.

Industrial Machinery: Essential in gearboxes, motors, pumps, and compressors. In gearboxes, they withstand forces from gear transmission, ensuring proper meshing and efficiency. For motors, they support the shaft, guaranteeing stable, quiet operation.

Aerospace: Critical in aero-engines, landing gears, and avionics. High-precision bearings support turbine and compressor shafts under extreme conditions. In landing gears, they endure massive shock and vibration.

Medical Devices: Applied in CT scanners, surgical robots, and dental equipment. In CT scanners, they enable precise rotation for clear imaging. In surgical robots, they enhance operation accuracy and safety.

Home Appliances: Used in washing machines, air conditioners, and refrigerators. In washing machines, they support motors and drums, ensuring stability. In air conditioners, they boost compressor efficiency and reliability.
