Jiangsu Fujie Blade Co., Ltd. has officially launched a new generation of 12×45 leaf springs and matching specialized mounting bracket assemblies for agricultural machinery. Optimized for the shock-absorption and clamping requirements of mainstream equipment—such as harvesters, field-incorporation machines, and straw shredders—this accessory set addresses the market gap for durable, shock-absorbing replacement parts for small and medium-sized agricultural machinery. It offers three key advantages—high fatigue strength, broad compatibility, and superior rust and wear resistance—providing a new, durable option for the nationwide agricultural machinery maintenance and manufacturing sectors.
Agricultural operating environments are demanding, with equipment constantly subjected to impacts from field soil, crop stalks, and debris. Conventional agricultural machinery springs often suffer from rapid loss of elasticity, breakage, and deformation or detachment of mounting points—issues that necessitate frequent replacements and significantly drive up maintenance costs for farmers. The newly launched 12×45 spring is forged from high-quality, thickened 65Mn spring steel with a cross-sectional profile of 12mm×45mm. Precision heat-treated via high-temperature quenching and multiple tempering cycles, it offers a stable elastic deformation range and withstands 100,000 cycles of continuous, reciprocating load without significant permanent deformation, making it ideally suited for the cushioning requirements of stalk-shredding rollers, pick-up mechanisms, and header hold-down assemblies. The spring features a matte black electrostatic powder coating that provides corrosion resistance against field mud and water; this finish prevents rusting and peeling during prolonged outdoor use, thereby substantially extending the component's service life.
The dedicated mounting bracket and 12×45 spring are engineered as a matched set; the bracket is formed from a single piece of thickened cold-rolled steel via stamping and bending. It features pre-drilled standard mounting holes, while precision-engineered retaining clips on both sides securely lock onto the spring's bent hooks, ensuring the assembly remains stable and does not slip or shift during operation on rough terrain. The bracket’s edges are deburred and smoothed to prevent scratching the spring's coating during installation. Its standardized mounting hole design is compatible with the frames of the vast majority of domestic small-to-medium-sized harvesters and straw incorporation machines, allowing for direct interchangeability in both OEM assembly and aftermarket repairs without the need for additional drilling or modification, thereby significantly boosting installation and removal efficiency. The components are supplied as a modular kit—with the spring and bracket paired at the factory—effectively resolving common industry issues such as dimensional mismatches and loose assemblies often encountered when sourcing parts separately.
According to the head of R&D at Jiangsu Fujie Blade Industry, the new product has undergone extensive field testing across regions including Northern Jiangsu, Anhui, and Shandong. Under high-intensity operating conditions—such as stalk incorporation and frequent wheat and rice harvesting—the product demonstrates a failure rate more than 60% lower than that of standard spring components. Manufactured in strict accordance with industry quality standards, every batch of springs undergoes sampling tests for elasticity, fatigue resistance, and salt spray performance; mounting brackets must meet load-bearing specifications before being cleared for warehousing and shipment. The product effectively balances cost-effectiveness for the aftermarket repair sector with the consistent quality required for bulk procurement by original equipment manufacturers (OEMs).
As agricultural mechanization continues to advance both domestically and internationally, there is a growing industry trend toward greater durability and the provision of complete component sets for agricultural machinery wear parts. With over a decade of expertise in agricultural machinery blades and shock-absorbing spring components, Jiangsu Fujie Blade Industry leverages its in-house, end-to-end production lines—covering steel processing, heat treatment, and coating—to continuously refine its products in response to the challenges faced in field operations. The launch of the 12×45 spring and mounting bracket assembly further expands the company’s product portfolio of shock-absorbing accessories. Moving forward, the company remains committed to the R&D of agricultural machinery components, aiming to boost efficiency and reduce costs in agricultural production through durable, cost-effective parts, while providing reliable, one-stop component solutions to machinery dealers and OEMs nationwide.
