YDTech® manufacturer of hardened needle rollers pins bearing steel(GCr15, SUJ2, 100Cr6, SAE52100) and needle roller bearing! supplier of hardenedstainless steel 440C cylindrical rollers or needle rollers hardened chrome steel(GCr15, SUJ2, 100Cr6, SAE52100) in china.

hardened steel needle rollers,usually HAC58~62. Needle rollers are small cylindrical rollers with a length that is typically several times their diameter. They are often used in needle roller bearings, which are used to reduce friction and facilitate motion in various applications. Needle rollers are typically made from hardened steel or other high-strength materials, and are capable of supporting high loads while maintaining a small profile.

Grooved pins, on the other hand, are cylindrical pins with one or more grooves around their circumference. The grooves are designed to allow the pin to compress or flex slightly when it is inserted into a hole, providing a tight fit and holding the components in place. Grooved pins are typically made from materials such as steel or stainless steel, and come in a variety of diameters and lengths. They are often used in applications such as machinery, aerospace, and electronics, where a secure fit is required.
