382300162 XCMG GR2605 motor grader preload rod

The 382300162 pretensioning rod is a specialized pretensioning actuator for the construction machinery industry. Its core function is to apply precise pretensioning force to equipment connections, compensating for connection gaps. Adaptable to heavy-duty operating scenarios, it has no customized features, is not a repetitive part, and is a key auxiliary component ensuring the stability of equipment connections. It can be directly matched with standard construction machinery interfaces without additional adaptation or adjustment.

Core Technical Parameters

Model 382300162 is a pretensioning rod specifically designed for construction machinery. Made of 40Cr alloy steel, it undergoes heat treatment, possessing high strength, fatigue resistance, and impact resistance, making it suitable for heavy-duty operations. The pretensioning force range is 0-50kN, supporting graded adjustment to meet pretensioning requirements under different working conditions. The operating temperature range is -40℃ to 120℃, adaptable to complex construction environments such as outdoor and high-temperature conditions. It is compatible with various construction machinery installation interfaces, ensuring convenient installation. The surface treatment employs a blackening + anti-rust coating process, effectively improving corrosion resistance and extending service life. The pre-tightening accuracy error does not exceed 5%, ensuring uniform and stable pre-tightening and preventing loosening.

Core Functions (Suitable for Construction Machinery Scenarios)

**Precisely applies pre-tightening force, completely eliminating gaps in equipment connections, preventing loosening and shifting during operation, and ensuring connection stability;** Dynamically compensates for gap loss in connections, maintaining equipment assembly accuracy and preventing component wear or failure due to excessive gaps;** Disperses stress concentration in connections, reducing the risk of component deformation, extending the overall service life of the equipment, and adapting to heavy-duty operation requirements;** Precisely matches the installation interface of construction machinery, allowing for direct assembly and use without additional adjustments, adapting to the pre-tightening requirements of various construction scenarios.

Suitable Scenarios and Applications

**Suitable for pre-tightening connections in various construction machinery, including excavators and loaders.** Widely used in heavy-duty operation scenarios such as mining and infrastructure construction, primarily for pre-tightening and fixing equipment connections and compensating for gaps, ensuring stable equipment operation. It can be used in conjunction with special connectors and seals to achieve integrated pre-tightening and fixing, improving operational safety and efficiency. It is suitable for complex construction environments such as outdoor, high temperature, and heavy load, and can be put into use directly after installation without additional adaptation or adjustment.
