The bodies of the AYWIparts CVDs are made of high-tensile-strength steel, thereafter they undergo the required HFC hardening and machining. High-precision angular placement of steel balls in the riffles contributes to the even load distribution, thereby providing long operation life. Quality control is carried out at all stages of assembling. A special coating that helps protect the body from corrosion is applied to the body frame of the CVDs. The set of the AYWIparts CVDs includes all the things needed for replacement or installation:
