A needle roller bearing without inner ring is a type of needle bearing that excludes the inner ring, commonly used when the shaft has been quenched and ground. FTM customizes needle roller bearings without inner rings, which effectively reduce the bearing's size and weight, minimize friction, and improve efficiency. These bearings can be tailored to meet specific customer requirements in terms of size, material, shape, and surface treatment, optimizing the bearing’s functionality.
FTM’s custom needle roller bearings without inner rings achieve precision grades of P2 and P4, making them suitable for applications such as automotive transmissions, machine tools, and printers.
