What is a one-way bearing?
  One-way bearing is a kind 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 shell of a one-way bearing contains a lot of rollers, needles or balls, and the shape of its rolling seat (cavity) makes it 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 bearing adopts forming and sintering process to make metal powder (or a mixture of metal powder and non-metal powder) into products. Based on the research on the characteristics of powders and process changes, the corresponding technical process is adopted to change the shape, performance and structure of the powders to become bearing products that meet different needs.
  The solid one-way bearing uses GCr15 bearing steel, the hardness is HRC61-65 after heat treatment, the bearing is small in size and has high load-bearing capacity, there is enough space for storing grease, and it can have a longer re-smoothing distance. Powder metallurgy one-way bearings and solid one-way bearings can completely lock the drive shaft when it is subjected to driving force.
  Prevents the lack of "locking" performance of traditional stamped outer ring one-way bearings. Main uses: textile machinery; printing machinery; automotive industry; household appliances; currency detectors. Series one-way needle roller bearings: It is composed of a stamped outer ring and a plastic holding frame. The holding frame can be equipped with plastic reeds or stainless steel reeds to guide the needle.
  The inclined raceway and needle roller on the outer ring are used for locking installation. HFL (clutch and bearing assembly): The supporting bearing is installed on both sides of the needle roller clutch and accepts radial load. As the supporting bearing, the needle roller and plastic holder assembly are used. Since there is no inner ring, the shaft wears a lot, so it is better to stop heat treatment on the operating shaft.
