From October 28 to October 31, 2025, PTC ASIA 2025 (Asia International Power Transmission and Control Technology Exhibition), the largest and most influential event in the power transmission sector in Asia, grandly kicked off at the Shanghai New International Expo Center. This year's exhibition gathered nearly 1,800 well-known exhibitors at home and abroad, attracting more than 140,000 professional visitors from over 100 countries worldwide. Twelve professional exhibition halls fully covered key fields such as hydraulics, pneumatics, and bearings, with both scale and influence reaching a new historical high. Lishui Jialida Bearing Co., Ltd. (hereinafter referred to as "Jialida"), a company with 18 years of industry experience, made a stunning appearance at Booth A128, Hall N3 with its core linear transmission products. With its product matrix featuring "high precision, high rigidity, and low loss", Jialida deeply aligned with the core theme of the exhibition - "Digital-Intelligent Integration, Green and Efficient", and provided global manufacturing customers with precision transmission solutions suitable for diverse scenarios.

As a professional manufacturer in the linear transmission field, Jialida showcased four core product series at the exhibition: super linear bearings, low-noise linear guide sliders, high-precision linear shafts, and ball screws. These products, with independently developed patented technologies and outstanding performance, became the focus of the booth, fully demonstrating the strength of "Made in China" in the precision transmission field.
The star exhibit of this exhibition - self-aligning super plastic linear ball bearings - is a patented product developed by Jialida after five years of R&D. With seven core advantages, this product redefines the performance standards of plastic linear bearings and can directly replace similar products of well-known brands such as Ningbo KBS, South Korea's SAMICK, Germany's INA, and THOMSON. It enables seamless replacement without adjusting the equipment installation dimensions, greatly reducing customers' brand switching costs and providing enterprises with a cost-effective upgrade option.
• Built-in Brass Sleeve + Self-Lubricating Structure: Integrating a high-hardness brass sleeve and a graphite solid self-lubricating system, the high-quality graphite has an oil absorption rate of over 60%, which can continuously release lubricating oil to effectively reduce friction and wear. Its wear resistance is significantly improved compared with ordinary plastic bearings, making it suitable for long-term high-frequency operation scenarios.
• Double-End Dustproof Sealing Ring Design: Adopting a double-end rubber sealing structure, it can not only block the intrusion of external impurities such as dust and debris but also prevent the leakage of internal lubricating oil, fundamentally reducing the risk of failures. Combined with the overall structural optimization of the product, its service life is 27 times that of ordinary linear bearings, greatly reducing customers' replacement and maintenance costs.
• German-Imported Raw Materials Ensure Quality: Using original BASF (Germany) engineering plastics, no recycled materials are used throughout the production process, ensuring the plastic surface is intact and free of impurities, with a uniform and stable structure. This avoids the risk of cracking and deformation caused by substandard raw materials and ensures the long-term reliable operation of the product.
• Full-Scenario Adaptability: It has excellent high-temperature resistance and can still operate stably in high-temperature environments; its operating noise is much lower than that of metal bearings, making it suitable for noise-sensitive scenarios such as medical treatment and food processing. At the same time, it has strong corrosion resistance and is not easy to rust, maintaining normal performance even in harsh environments such as humidity, acid, and alkali, covering multiple fields including traditional manufacturing and high-end equipment.
As another core patented product of Jialida, the low-noise linear guide slider solves the industry pain point of "high operating noise" in the automation field with four core advantages. Its performance is comparable to similar products of Taiwan's HIWIN, while its price is more competitive, effectively reducing customers' procurement costs.
• Patented Raceway Silent Structure: The independently developed patented steel ball silent support frame is built into the raceway. By optimizing the contact angle and movement trajectory of the steel balls, the impact friction between the steel balls and the raceway is reduced. Combined with special lubricating oil, it achieves ultra-silent operation, with noise controlled below 40 decibels, far lower than the industry average, completely solving the problem of equipment operating noise.
• Self-Aligning to Adapt to Complex Installation: It has an installation deviation compensation capability of ±0.15mm, and can still operate stably even when the installation accuracy is slightly insufficient, reducing the difficulty of installation and commissioning and improving the overall operational stability of the equipment.
• High Wear Resistance Extends Service Life: The guide rail body is made of high-carbon chromium bearing steel treated with quenching, with a surface hardness of HRC 58-62. The slider is equipped with a reinforced wear-resistant cage, which can effectively resist wear and impact. Under the working condition of 12 hours of operation per day, its service life can reach more than 8,000 hours, reducing production interruptions caused by frequent replacements.
As the core guiding component of the guide rail system, the linear shafts exhibited this time create a motion benchmark with extreme precision. The diameter tolerance is strictly controlled at G6 level, and combined with precision grinding technology, the surface roughness is as low as Ra 0.2μm. In terms of key geometric accuracy, the straightness error within a length of 300mm is ≤0.03mm, and the roundness is ≤0.01mm, ensuring stable and deviation-free guidance. The product is made of high-carbon chromium bearing steel treated with professional quenching, with a hardness of HRC 58-65 and excellent wear resistance, which can withstand long-term high-frequency friction without easy wear. Its surface is treated with special anti-rust treatment, suitable for multiple working environments such as humidity and corrosion. When used with linear bearings, it can form an efficient guiding system, which is widely used in automated conveying equipment, photovoltaic panel adjustment mechanisms, textile machinery and other scenarios, providing a stable and reliable linear motion benchmark for equipment.
Through strict grinding, assembly, and testing processes, Jialida's ball screws achieve micron-level positioning accuracy and a transmission efficiency of over 90%. They can completely replace similar products of Taiwan's TBI, with seamless matching of installation dimensions and performance parameters, allowing direct replacement without adjusting the equipment structure. At the same time, their prices are more competitive, significantly reducing customers' procurement costs. In terms of delivery efficiency, relying on its own production lines and stable supply chain, the delivery cycle for standard models is as short as 7-10 days, and customized models can also be quickly responded to according to order requirements, avoiding production delays caused by long waiting for goods.
In terms of performance, the self-lubricating models on display are equipped with a long-acting lubrication module, which can maintain stable operation without frequent maintenance; the preloaded models can realize negative axial clearance adjustment, greatly improving axial rigidity. This product performs outstandingly in fields such as industrial robot joints, CNC machine tool feed systems, and woodworking machinery. It can accurately convert rotational motion into linear motion, and its DN value of ≥140,000 is suitable for high-speed operation requirements, becoming a core component for precision control of high-end equipment.
