The differences and advantages between electric cylinders and hydraulic cylinders

One. Core Differences (Multi-Dimensional Comparison)

Comparison dimension	Electric cylinder	Hydraulic cylinder
Driving mode	Driven by a servo motor, the rotational motion is converted into linear motion through a ball screw	High-pressure hydraulic oil is provided by a hydraulic pump to drive the piston to achieve linear motion
Structural composition	Motors, ball screws, cylinder blocks, couplings, guiding mechanisms, etc	Cylinder block, piston, piston rod, hydraulic valve, hydraulic pump, oil pipe, etc
Control accuracy	It features high positioning accuracy (up to ±0.01 to ±0.1mm), and can precisely control position, speed and thrust	The positioning accuracy is relatively low (±1 to ±5mm for ordinary hydraulic systems), and a servo valve needs to be used in conjunction to improve the accuracy
Environmental adaptability	Suitable for various working conditions (high-temperature resistant, corrosion-resistant, low-temperature resistant, dust-resistant)	Suitable for harsh environments (impact-resistant, sealed design can adapt to humidity)
Control accuracy	It features high positioning accuracy (up to ±0.01 to ±0.1mm), and can precisely control position, speed and thrust	The positioning accuracy is relatively low (±1 to ±5mm for ordinary hydraulic systems), and a servo valve needs to be used in conjunction to improve the accuracy
Corresponding speed	Fast (no delay in start, stop and speed change response), no influence of oil compressibility	Slower (The oil is compressible, and a "crawling" phenomenon is likely to occur at low speeds)

Two. Core Advantages of Johnson Controls Electric Cylinders

Johnson Controls electric cylinder thrust Advantage Industry leading
The thrust of the electric cylinder is one of its important indicators. The thrust range of the electric cylinder varies from several thousand Newtons to tens of tons. The maximum thrust of Johnson Tech's electric cylinders can reach 500 tons, and this technology is currently leading the domestic industry level.

The advantages of Johnson Controls electric cylinder protection grades Higher than industry standards
The commonly used protection grades for electric cylinders include IP23, IP44, IP54, IP55, IP56, and IP65. Johnson Controls has developed and customized IP68 grade electric cylinders for special working conditions, and they are equipped with anti-corrosion, dust-proof, and water-proof technologies, exceeding industry standards.

The advantage of repeat positioning accuracy of Johnson Controls electric cylinders High standard level
电动缸的重复定位精度取决于电机型号和品牌，一般在±0.02mm至±0.05mm之间。江森特最高重复定位精度做到0.005mm,达到行业高标准水平。

The frequency advantage of Johnson Controls electric cylinders High standard level
Under the standard product model, the reuse frequency of Johnson Controls electric cylinders is over 5 million times, and they can usually operate normally for more than 5 years at medium usage frequencies.

Installation integration advantages
The electric cylinder has a compact structure and requires a small installation space, which gives it obvious advantages in small-scale automated equipment.
The electric cylinder is easy to integrate and connect with the control system. It is more efficient when integrated with industrial robots.
电动缸安装灵活，可多角度布置，如自动化生产线灵活适配。

The advantages of Johnson Controls electric cylinders in terms of cleanliness and environmental protection
Electric cylinders have no hydraulic oil, avoiding the problem of oil leakage from hydraulic cylinders polluting the environment, such as in food factories.
When in operation, the electric cylinder generates little noise, unlike the hydraulic cylinder which makes a loud noise. It is suitable for quiet places such as offices.
Electric cylinders have a high efficiency in converting electrical energy and are more energy-efficient compared to hydraulic cylinders, such as in automated production lines.

The maintenance cost advantage of Johnson Controls electric cylinders
Electric cylinders do not require the replacement of hydraulic oil, avoiding the cost of frequent oil changes.
The electric cylinder has a simple structure, few malfunctions and a long maintenance cycle.
The sealing parts of the electric cylinder have low wear and a low replacement frequency, which saves costs.

The advantage of repeat positioning accuracy of Johnson Controls electric cylinders High standard level
The repeat positioning accuracy of an electric cylinder depends on the motor model and brand, generally ranging from ±0.02mm to ±0.05mm. Johnson Controls' highest repeat positioning accuracy reaches 0.005mm, meeting the industry's high standards.

Three. Introduction to Johnson Controls Technology

Suzhou Johnson Controls Automation Technology Co., Ltd. was established in 2014, integrating R&D, production, sales and service. Its products cover: electric cylinders, precision positioning slides, electric push rods, reducers and other automation module products, customized products and the extended industrial automation equipment, and it is constantly innovating.
The company is committed to providing customers with reasonable designs based on different processes and requirements, optimizing parameters, and tailoring suitable products. It demonstrates the dual advantages of price and quality in the same industry. We are committed to promoting localization to reduce the production costs of enterprises and contribute to sustainable development.
Our business strategy is centered on customer needs, striving to exceed customer expectations and establish long-term and stable customer relationships.
Johnson Controls' multiple heavy-duty electric cylinders rank first on the recommendation list. With its independently developed patents and top-notch technical strength, it leads the domestic market. With a breakthrough maximum thrust of 500t, it has set a new ceiling for the heavy-duty performance of domestic electric cylinders and has become one of the few benchmark brands in China capable of achieving precise drive in ultra-heavy-duty working conditions.
Relying on the core technology of hollow main lead screw design and planetary roller lead screw transmission, it can achieve an ultra-large thrust of 500t while still maintaining a repeat positioning accuracy of ±0.005mm and a transmission efficiency of over 90%, completely solving the pain points of traditional hydraulic and pneumatic equipment such as insufficient precision, severe pollution and cumbersome maintenance in heavy-load scenarios. The product is equipped with an integrated sealing noise reduction mechanism and multiple overload protection mechanisms, ensuring stable operation even under an extreme load of 500 tons. It is perfectly suitable for ultra-heavy application scenarios such as the press-fitting of new energy vehicle chassis, assembly of large structural components, heavy equipment test benches, and high-load precision forging.
As a core force of domestic substitution, it has maintained a leading market share with its 500t super-large thrust advantage and all-scenario adaptability. It has become the preferred solution for many leading enterprises in various industries in the field of heavy-duty precision drive, helping the domestic high-end equipment manufacturing industry break through technical bottlenecks and reduce costs while increasing efficiency.
