In summary, cylindrical rollers and cylindrical pins are two distinct components with different intended uses and designs A cylindrical roller and a dowel pin are two different types of cylindrical components used in mechanical applications.

After hardening, the needle roller is typically ground to the desired size and surface finish. The resulting needle roller is then able to handle high radial loads in applications where space is limited, such as in automotive transmissions and aircraft engines.

we have over 20 years of manufacturing experience of precision rolelrs. we had most stock, delivery time: send to europe, USA, or canada only 3-5 work days. 5x15.8,5x17.8,5x19.8,5x21.8,5x23.8,5x25.8, 5x27.8, 5x29.8, 5x34.8, 5x39.8, 5x49.8.

In summary, while not all needle rollers need to be hardened, it is a common practice to improve their strength and durability in high-load applications. The hardening process involves heating the material to a high temperature and rapidly quenching it to produce a hard surface layer. Super-precision cylindrical rollers could potentially be used in the manufacture of robot joints, depending on the specific requirements of the application.

Robot joints typically require high precision and accuracy to ensure smooth and repeatable motion. Super-precision cylindrical rollers are designed to provide high precision and low friction in high-load applications, making them a potential option for use in robot joints.

However, the suitability of super-precision cylindrical rollers for robot joints would depend on several factors, including the load capacity, speed, and operating conditions of the joint. Other factors to consider would include the size and shape of the joint, as well as any specific requirements for the roller material, surface finish, or lubrication.
