Dongfeng KInland truck parts Flip arm with rubber sleeve assembly 5001025-C0102

A key function of the 5001025-C0102 assembly is its high-performance rubber sleeve, designed to absorb vibrations and protect Kinland’s suspension/chassis components. The sleeve is made of specialized EPDM rubber (Shore A hardness 65±5), optimized for elasticity and fatigue resistance—capable of withstanding 100,000+ compression cycles without hardening or cracking. When the truck encounters rough terrain or heavy loads, the rubber sleeve acts as a buffer between the flip arm and adjacent metal brackets, reducing vibration transmission by 40% and preventing metal-to-metal contact. This minimizes wear on the flip arm’s shaft, brackets, and surrounding components (e.g., bushings, bolts), extending their service life by 30%. For Kinland trucks operating on unpaved construction sites or bumpy rural roads, this cushioning also reduces cabin vibration, enhancing driver comfort during long shifts

Built to handle Kinland’s heavy-duty load requirements, the 5001025-C0102 assembly’s flip arm features a robust, high-strength design. The arm is crafted from Q345 carbon steel, undergoing forging and heat treatment (880°C quenching + 550°C tempering) to achieve a tensile strength of 510MPa—capable of supporting 2,500kg static load without deformation. Its surface is treated with a zinc-nickel coating (15-20μm thickness) that passes 1,000-hour salt spray tests, resisting rust and corrosion from road salt, rain, or mud. The arm’s pivot shaft is precision-ground to a smoothness of Ra 0.8μm, reducing friction against the rubber sleeve and ensuring consistent rotation. Rigorous durability tests—including 200,000+ pivot cycles and 500-hour load testing—confirm the flip arm maintains structural integrity for 7+ years in commercial use, minimizing replacement frequency and fleet maintenance costs

The 5001025-C0102 assembly’s flip arm plays a critical role in enhancing Kinland’s chassis and suspension flexibility, adapting to dynamic road conditions. Its 120° pivot range allows the suspension to compress and extend freely over bumps, ensuring consistent tire contact with the road and improving traction—critical for preventing skidding during wet or icy weather. In Kinland’s rear suspension systems, the flip arm acts as a link between the axle and frame, distributing load evenly across the suspension components and reducing stress on individual parts. For trucks equipped with adjustable suspension (e.g., for variable cargo weights), the flip arm’s smooth pivot action enables easy height adjustment without binding. This versatility ensures the assembly performs reliably across Kinland’s diverse applications, from light urban delivery to heavy construction material transport

The 5001025-C0102 assembly is designed for user-friendly maintenance and installation, saving time for fleet technicians. The rubber sleeve features a split design that allows it to be replaced without removing the entire flip arm from the truck—simply slide the old sleeve off the shaft and snap the new one into place, taking 5 minutes or less. For full assembly installation, the flip arm’s pre-drilled mounting holes align with Kinland’s chassis brackets, requiring only basic hand tools (wrenches, sockets) and no specialized equipment. A detailed installation manual (with step-by-step diagrams) is included, guiding technicians through alignment and torque specifications (25-30 N·m for mounting bolts). This ease of installation and maintenance reduces truck downtime, a critical advantage for Kinland operators who rely on their vehicles for time-sensitive deliveries or construction projects
