【One-way needle roller bearings】: Also known as needle roller clutches, they consist of a stamped outer ring and a plastic cage; the cage can come with either a plastic reed or a stainless steel reed to guide the needle rollers, while the inclined raceway on the outer ring and the needle rollers act as the locking device. They feature grooves on the surface and are primarily targeted at diabolo manufacturing companies. Solid-ring one-way needle roller bearings have also been introduced, mainly for fitness equipment companies. Ultra-thin one-way needle roller bearings have been developed for precision machinery companies. The company also specializes in producing one-way bearings for fishing gear reels, special single bearings, and one-way bearings for remote-controlled model cars (HF, HFL, FC, FCB, RCB, RC, F, IWC, EWC, DC, CSK, CKB(B200), ASNU, CKA, FWD, NF, etc., as well as special specifications of stainless steel fishing gear one-way bearings). Stamped outer ring one-way needle roller bearings are divided into (HF, HFL, RCB, RC, FCB, FC). Those with dimensions conforming to current standards are classified as standard models; those with dimensions not meeting the above standards are classified as special models.

【Main structure of one-way needle roller bearings】:  1. EG one-way bearing, one-way needle roller bearing EG－－stamped outer ring needle roller clutch (one-way bearing) can be used as a converter, check device, or overrunning clutch.  2. HF (needle roller clutch), composed of a stamped outer ring and a plastic cage; the cage can come with either a plastic reed or a stainless steel reed to guide the needle rollers, while the inclined raceway on the outer ring and the needle rollers act as the locking device.  3. HFL (clutch and bearing assembly), with support bearings mounted on both sides of the needle roller clutch to withstand radial loads. The support bearings consist of needle rollers and a plastic cage assembly.
