Jiesheng Transmission Linear Shafts: Providing Stable Guidance and Support for New Energy Equipment
Introduction
With the explosive growth of new energy industries such as lithium-ion batteries, photovoltaics, and hydrogen energy, downstream production equipment is rapidly evolving toward higher speeds, greater precision, and continuous operation over extended periods. Linear guide rods (chrome-plated rods / piston rods), as core components of reciprocating motion mechanisms, guide and support structures, and lifting actuators, are widely used in key processes such as electrode sheet winding, silicon wafer transport, battery assembly, and fuel cell stack pressing. Their surface hardness, coating quality, surface finish, and roundness accuracy directly determine the operational stability of the equipment, product yield, and maintenance intervals.
In high-cycle production scenarios for new energy equipment, linear shafts are often subjected to harsh operating conditions, including high-frequency reciprocating motion, continuous loads, and specialized cleanroom environments. Many equipment failures and precision degradations stem from inadequate shaft selection and quality issues: scoring and jamming caused by coating peeling; rapid wear resulting from insufficient surface hardness; excessive operating resistance due to poor surface finish; and contamination of cleanrooms caused by poor rust resistance… These issues not only drive up equipment operation and maintenance costs but also directly impact the production yield of new energy products. For new energy equipment, high-quality linear shafts are the unseen core that ensures the long-term, stable operation of production lines.
Section I: Linear Shafts: The Core of Guidance and Support for New Energy Equipment
In new energy production equipment-such as lithium-ion battery, photovoltaic, and hydrogen energy systems-linear shafts, when paired with linear bearings, form a sliding guidance assembly that performs the core functions of motion guidance, load support, and reciprocating positioning. They are indispensable foundational components in transfer mechanisms, lifting platforms, winding mechanisms, and press-fitting equipment. Their performance permeates the entire production process, directly affecting the operational efficiency and product consistency of the entire production line.
Four Core Values
Precise Guidance and Support to Ensure Process Accuracy: High-precision linear shafts strictly control tolerances for roundness, cylindricity, and straightness. When paired with linear bearings, they enable backlash-free sliding guidance. In precision processes such as electrode stacking, silicon wafer alignment, and battery sorting, they ensure micron-level positioning accuracy and smooth motion, preventing defects such as electrode misalignment, silicon wafer chipping, and assembly deviations caused by guidance errors.
High-Hardness, Wear-Resistant Coating for Extended Equipment Lifespan: A combination of surface hardening treatment and a hard chrome plating structure significantly enhances the shaft's surface hardness and wear resistance. This substantially reduces wear rates under high-frequency reciprocating and continuous-load conditions, effectively extending equipment maintenance intervals and service life to meet the demands of 24-hour non-stop production on new energy production lines.
Smooth, Low-Friction Operation Suitable for High-Speed Conditions: The ultra-precision ground and polished surface achieves mirror-like smoothness. Combined with the lubrication system, this ensures extremely low sliding friction resistance. During high-speed reciprocating operation, it generates minimal heat and low noise, making it suitable for fast-paced production scenarios such as electrode sheet winding and high-speed sorting. This reduces equipment energy consumption and enhances operational stability.
Multiple Material Options for Special Environments: We offer a variety of material options, including chrome-plated carbon steel, stainless steel, and bearing steel, to meet the requirements of general, cleanroom, and corrosion-resistant environments, respectively. These shafts operate stably in electrolyte, humid, and dusty environments, satisfying the diverse environmental demands of different new energy manufacturing processes.

High-quality base material + hardening treatment, resulting in excellent mechanical properties
Carefully selected high-quality 45# carbon steel, GCr15 bearing steel, 304/316 stainless steel, and other high-quality base materials. These can undergo heat treatments such as high-frequency quenching and tempering as required, ensuring the core possesses good toughness while the surface achieves high hardness standards. This combination provides both impact resistance and wear resistance, making the material resistant to deformation and fracture under alternating load conditions and ensuring the mechanical stability of equipment during long-term operation.
Precision Hard Chrome Plating with Uniform Coating and Strong Adhesion
An environmentally friendly hard chrome plating process is employed, ensuring uniform and controllable coating thickness with strong adhesion; the coating is resistant to peeling or flaking even during long-term repetitive operation. The chrome-plated surface is dense and smooth, offering excellent rust resistance and wear resistance, and significantly reducing the coefficient of sliding friction. It is suitable for both dry, clean lithium-ion battery production facilities and slightly corrosive production environments such as those in the photovoltaic and hydrogen energy industries.
High-Precision Grinding and Polishing, Stable Dimensional Accuracy
Through multiple stages of precision external cylindrical grinding and ultra-fine polishing, key geometric tolerances-including outer diameter tolerance, roundness, cylindricity, and straightness-are strictly controlled. Surface roughness can reach below Ra 0.4, and mirror-like finish ensures smooth operation without jamming. Full-dimension batch inspection ensures high product consistency, eliminating the need for secondary adjustments during mass installation and significantly reducing assembly costs for equipment manufacturers.
