A one-way bearing is a type of bearing that can rotate freely in one direction and lock in the other direction. One-way bearings are also called overrunning clutches, but they are named according to different industries and functions. The metal housing of the one-way bearing contains a lot of rollers, needles or balls, and the shape of its rolling seat (cavity) makes it can only roll in one direction, and it will produce a lot of resistance in the other direction ( The so-called one-way).

  Powder metallurgy one-way bearings use forming and sintering processes to make metal powder (or a mixture of metal powder and non-metal powder) into products. Based on the study of the characteristics of powder and the characteristics of process changes, the corresponding technical processes are used to modify the shape and performance of powder and their organizational structure to become a bearing product that meets different needs.

The solid one-way bearing uses GCr15 bearing steel, the hardness after heat treatment is HRC61-65, the bearing is small in size and has high load-bearing ability, there is enough space to store smooth grease, and there can be a longer return smooth period. Powder metallurgy one-way bearings and solid one-way bearings can completely lock the transmission shaft when it is driven.

It prevents the problem of lack of locking performance of traditional stamping outer ring one-way bearings. The main uses are: textile machinery; printing machinery; automotive industry; household appliances; banknote detector. Series of one-way needle roller bearings: It consists of stamped outer ring and plastic holding frame. The holding frame can be equipped with plastic reed or stainless steel reed to guide the needle.

The inclined raceway and needle roller on the outer ring are installed as a lock. HFL (clutch and bearing assembly): The supporting bearing is installed on both sides of the needle roller clutch and receives radial load. As the supporting bearing is the needle roller and plastic holding frame assembly. Because there is no inner ring, the wear on the shaft is large, so the heat treatment should be stopped for the application shaft.
