Hebei Speed Torque Transmission Technology Co., Ltd. (established in 2017, with a factory area of 3,000–5,000 sqm and a team of 101–200 employees) proudly presents our Wear Resistant Cross Shaft With Needle Bearings Universal Joint Construction Machinery Kit. This kit is engineered to deliver exceptional durability and reliable torque transmission under the harshest construction site conditions. Combining premium alloy steel construction, advanced needle roller bearings, and a specialized wear-resistant surface treatment, our universal joint cross shaft effectively reduces downtime and maintenance costs for heavy equipment such as excavators, loaders, and bulldozers. With an annual export value exceeding US$5 million and ISO9001 quality management system certification, we ensure that every kit meets rigorous international standards.
Product Features & Technical Specifications
Premium Material: Made from high-quality alloy steel (20CrMnTi or equivalent), carburized and quenched to achieve a surface hardness of HRC 58–62, providing outstanding wear resistance.
Needle Roller Bearings: Integrated needle bearings offer high load-carrying capacity, reduced friction, and smooth rotational motion, extending the service life of the universal joint.
Precision Machining: CNC machining ensures tight tolerances (±0.02mm on critical dimensions), resulting in balanced rotation and minimized vibration during operation.
Corrosion & Wear Protection: Optional phosphate coating or black oxide finish enhances resistance to rust and abrasion in muddy or dusty environments.
Interchangeable Design: Designed to directly replace OEM parts on popular construction machinery brands (Caterpillar, Komatsu, Volvo, etc.), allowing quick installation.
Customizable Dimensions: Available in various shaft diameters (20mm to 80mm) and lengths (100mm to 500mm) to fit different equipment models.
