Product Introduction

A2203100 OEM-spec Corrosion-resistant Low-friction Drive Shaft for Lifan

Product Advantage

1. High-Tensile Material with Industrial-Grade Durability

   Our drive shaft for Lifan is made of 40Cr alloy steel, which has a tensile strength of 980MPa and a yield strength of 785MPa—35% higher than ordinary carbon steel. The surface is treated with hot-dip galvanization (zinc layer thickness 85-100μm), passing 1000-hour neutral salt spray testing (in line with ISO 9227 standards). This ensures the drive shaft resists corrosion and wear even in harsh environments, significantly extending its service life.

2. Precision CNC Machining for Zero-Fit Error

   We adopt 5-axis CNC machining technology for the drive shaft’s spline and flange, achieving a machining accuracy of ±0.01mm. This ensures seamless fitting with Lifan’s drivetrain components, reducing torque loss to less than 2% during power transmission. The precision structure also avoids abnormal wear caused by poor fitting, maintaining stable performance of the entire drivetrain.

3. Dynamic Balancing & Vibration Reduction Optimization

   Every drive shaft for Lifan undergoes dynamic balancing testing at 3500rpm, with a balance accuracy of G2.5 (far higher than the industry’s common G6.3 standard). It is equipped with a silicone damping ring (Shore hardness 70±3) that reduces vibration amplitude to ≤0.1mm, lowering driving noise by 10-15dB and improving driving comfort.

4. Rigorous Fatigue & Temperature Resistance Testing

   The drive shaft has passed 1.2 million cycles of fatigue testing (exceeding the industry’s 800,000-cycle standard) without cracks or deformation. It also undergoes extreme temperature testing (-50℃ to 150℃), maintaining stable torque transmission performance in both frigid and high-temperature environments. These tests guarantee a service life of over 90,000km for the product.

5. 100% Compatibility & Quick Installation Design

   Designed according to Lifan’s original drivetrain parameters, the drive shaft achieves full compatibility with corresponding Lifan models. It comes with pre-assembled grease (high-temperature resistant, -30℃ to 180℃) and standard mounting hardware, allowing professional mechanics to complete installation in 30-40 minutes—saving time and labor costs for repair scenarios.

Technical Parameters

Product Uses

Here are specific application scenarios of drive shaft:

1. Humid Coastal & Marine Areas

   With 1000-hour salt spray resistance (ISO 9227 standard), the drive shaft withstands corrosion from sea breeze and moisture. It maintains stable torque transmission for vehicles frequently used near coasts, avoiding rust-related failures that occur in ordinary drive shafts within 6-8 months.

2. High-Temperature Desert Regions

   Its -50℃ to 150℃ operating range ensures performance in desert heat. Even when ambient temperatures reach 45℃+, the silicone damping component and high-temp grease (-30℃ to 180℃) keep vibration ≤0.1mm, preventing overheating damage.

3. Rural & Unpaved Road Conditions

   The 40Cr alloy steel body (980MPa tensile strength) resists impact from potholes and gravel. Combined with 1.2 million-cycle fatigue resistance, it endures frequent jolts—extending service life to ≥90,000km, 25% longer than standard drive shafts in rough terrain.

4. Daily Urban Commuting & Fleet Use

   With ≥97% torque efficiency and ≤65dB noise, it suits stop-and-go city driving. For fleets, its 30-40 minute quick installation reduces downtime, while 100% Lifan compatibility eliminates fitting issues, cutting maintenance costs by 15-20% annually....

Product Operate Guide

1. Before installation, check that the shaft body is free of deformation and the coating is intact. Use a torque wrench to tighten the flange bolts to the standard of 35-45N・m, avoiding over-loosening or over-tightening.

2. Every 30,000km of driving, inspect the damping components and replenish high-temperature resistant grease (-30℃ to 180℃) to ensure a transmission efficiency of ≥97% and extend the service life to over 90,000km.
