[0002] Flat bearings consist of a flat cage assembly with needle rollers or cylindrical rollers or steel balls and flat washers. They are generally divided into needle roller bearings and ball bearings. The use of high-precision cylindrical rollers (needles) increases the contact length, allowing the bearing to obtain high load capacity and high rigidity in a smaller gap space. In addition, if the surface of the adjacent components is suitable for the raceway surface, the gasket can be omitted, which can make the design compact. The cylindrical surface of the needle rollers and cylindrical rollers used in flat needle roller bearings and flat cylindrical roller bearings is a modified surface, which can reduce edge stress and extend service life.
