YDTech® manufacturer of one way clutches, needle roller bearings or assemblies(HF,HFL,ASNU,CKA,FWD,NF)! supplier of drawn cup roller clutches (IWC,EWC,DC,CSK,CKB,FC,FCB,RCB,RC,F) in china.

what's one way bearing?

one way bearing is free to rotate one direction, while in the other direction a bearing on the lock. One-way bearings inside the metal case, contains a lot of a roller, needle, or ball, and the rolling seat or hole shape so that it can only scroll in one direction, while in the other direction with great resistance , so called "oneway".

drawn cup needle roller one way clutches have a smallest radial section height among all clutches. This makes optimum use of the available space and allows compact designs. these clutches are suitable for transmitting high torque. they are normally used for converters, non-return devices and transcendental clutches.

HF series is composed of thin walled drawn outer ring and plastic cage. there are a series of ramps on its inside diameter and steel springs in the plastic cage. needle rollers, which are retained and guided by a plastic cage, form the clamping elements.

HFL series has two integral radial bearings arranged on both sides of needle roller clutch. they can therefore support radial forces in particularly space-saving bearing arrangements.

a wide range of line-type HF, HFL, FC, FCB, RCB, RC, F, IWC, EWC, DC, CSK, CKB (B200), ASNU , CKA, FWD, NF ... According to the different needs of internal and external changes in a flexible structure, its outer ring is made from alloy steel precision stamping, after special treatment to enhance the wear resistance of the load bearing capacity is extremely, retainer to guide the use of high toughness PA66 2μm needle to obtain a better precision bearing steel and the rotating performance and maximum torque transmission.

because the radial thin section, so the moment of inertia clutch a small needle. Each needle by the spring in support of a separate, so allowing a higher conversion frequency. At high frequency, the driving force should in general be imported through the shaft.
