Our roller cold former is a specialized solution for manufacturing precision rollers, needle rollers, and small bearing components with unmatched efficiency and consistency. Designed to meet the stringent quality demands of industries such as bearings, automotive transmission systems, and precision machinery, this machine integrates advanced cold heading technology with robust engineering to deliver superior performance in high-volume production.
Core Features & Purpose-Built Design of the Roller Cold Former
1. Precision Roller/Needle Roller Forming
● Dimensional Accuracy: Capable of processing components with a maximum cutting diameter of 10.6mm and a length range of 11-30mm, the TR-101 is ideal for standard and micro-sized rollers (e.g., cylindrical rollers, needle rollers) while ensuring tight geometric tolerances and smooth surface finishes.
● Single Die-Punch Efficiency: Utilizes 1 set of high-precision dies and punches to achieve chip-free cold heading, minimizing material waste and enhancing metal grain flow integrity. This process significantly improves wear resistance and fatigue strength in finished rollers.
2. High-Speed Continuous Production
Operates at speeds up to 380 pieces per minute, enabling mass production to meet the high-volume demands of the bearing industry. Adjustable speeds (100-380pcs/min) allow flexibility when working with diverse materials, such as bearing steel (e.g., GCr15) or stainless steel.
3. Power & Stability Assurance
● 30kW Main Motor: Delivers exceptional forming force for single-strike deformation of high-hardness materials, eliminating internal defects caused by multi-stage processing.
● Hydraulic System Precision: A 1.1kW oil pump motor powers a synchronized hydraulic system, ensuring precise feeding, cutting, and forming-critical for maintaining consistency in long, slender needle rollers.
Industry Applications
● Bearing Manufacturing: Mass-produce cylindrical rollers, needle roller bearings, and critical components for automotive hub bearings or transmission systems.
● Precision Machinery: Fabricate ultra-precision parts like miniature rollers (e.g., watch bearings) or linear guide needle rollers.
