the manufacturing process of high precision needle rollers is complex and requires specialized equipment and expertise.

raw material: the first step is to select the appropriate raw material, usually bearing steel or other high-quality steel alloys that are known for their high strength, durability, and resistance to wear and fatigue.

cutting , shaping: the next step is to cut the raw material into the desired length and shape using specialized cutting and shaping machines. The goal is to create a cylindrical roller with the correct dimensions and surface finish.

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.

heat treatment: the rollers are then subjected to a heat treatment process to improve their mechanical properties, such as hardness, strength, and toughness. This typically involves quenching and tempering, which involves heating the rollers to a specific temperature, then rapidly cooling them to create a hard, durable surface layer.

grinding and finishing: once the rollers are heat treated, they are typically ground to achieve a high level of precision and a smooth, uniform surface finish. this is done using specialized grinding machines that are capable of removing extremely small amounts of material to achieve the desired shape and surface finish.

inspection and quality control: finally, the rollers are inspected to ensure that they meet the required specifications and quality standards. this typically involves using advanced measuring and testing equipment to verify the dimensions, roundness, and surface finish of each roller.

the manufacturing process of high precision cylindrical rollers is complex and requires specialized equipment and expertise. the goal is to produce rollers that are highly accurate, durable, and reliable, with the mechanical properties needed to handle the extreme loads and speeds encountered in many industrial applications.

we are professional manufacture of bearing rollers and cylindrical needle rollers. we produce rollers of diameter 0.5 mm to 60 mm. the rollers could satisfy the request of DIN 5402 G2 rollers.
