The ball joint tie rod bearing for construction machinery is a core component connecting the mechanical actuator and the transmission system. It is widely used in the steering, boom, and bucket connection parts of equipment such as excavators, loaders, cranes, and bulldozers.
Product Highlights
Core advantage: Addressing the three major pain points in the industry
Superior Wear Resistance, 50% Longer Service Life
- Material Upgrade: The ball head is made of 20CrMnTi alloy with carburizing and quenching treatment, achieving a surface hardness of HRC58-62, which provides much better wear resistance than ordinary carbon steel; the tie rod is integrally forged from 45# forged steel, with a tensile strength of ≥600MPa.
- Lubrication Optimization: Equipped with high-density lithium-based grease and double-layer dust-proof sealing rings, it effectively blocks the intrusion of sand and mud, reduces dry friction loss, and extends the service life by more than 50% compared with similar products.
Precise Adaptation, Easy Installation
- Standardized Production: Strictly complies with ISO 12240-1 construction machinery bearing standards, compatible with mainstream brand models such as Caterpillar, Komatsu, Sany, and XCMG, covering over 1,000 commonly used specifications.
- Structural Optimization: The ball head and tie rod adopt double fixing of thread fastening + pin positioning. No special tools are required for installation, and quick assembly can be achieved by aligning the hole positions, reducing labor costs.
Stable Pressure Resistance, Adaptable to Complex Working Conditions
- Strong Load-Bearing Capacity: The spherical contact design disperses stress, with a rated dynamic load of 80-500kN and a maximum static load of 1,200kN, meeting the heavy-load operation needs of heavy equipment.
- Corrosion Resistance: The tie rod surface adopts double protection of electrophoretic coating + galvanizing, passing a 480-hour salt spray test, and is not easy to rust in humid, dusty, acid, and alkaline environments.
Application scenarios
Quality Assurance
