Linear Actuator IP66
Basics
1. What's a Linear Actuator JC60DN?
A linear actuator with the protection class JC60DN is an electric actuator with an integrated 24V DC motor. The motor's rotary motion drives a spindle inside the actuator tube through a gear mechanism, which in turn moves a running nut in an axial direction. The cylinder tube mounted on the nut then performs the required lifting movement. The enclosure of the motor and spindle-nut assembly achieves protection class IP66. The protection class is defined as follows:
IP: This stands for "Ingress Protection" or "International Protection" and is an international standard that specifies the protection of electrical devices and enclosures against the ingress of solids (e.g., dust) and liquids (e.g., water).
66: These two numbers represent the protection levels against the ingress of dust and water. In this case, IP66 means:
The first "6" stands for protection against the ingress of solid objects and indicates that the linear actuator is completely dust-tight. This means that no dust can enter the enclosure, even in large quantities.
The second "6" stands for protection against the ingress of water. A linear actuator with IP66 rating is protected against powerful water jets, meaning it is water-resistant and can withstand high-pressure water. It is also protected against rain and splashing water.
2. When is the Linear Actuator JC60DN suitable?
A linear actuator is well-suited for environments where dust and moisture could be an issue, such as in industrial settings, damp or wet outdoor environments, food processing, and other demanding applications. The IP66 rating provides assurance that the actuator will operate reliably under these conditions, with no dust or water ingress into the enclosure.

3. Two variants of actuators are distinguished:
1) Adjustments up to 2000N
When the actuator is adjusted without a load, speeds of up to 20mm/s can be achieved. Under full load, the actuator adjusts at 12mm/s, with the speed-to-load curve being linear.
2) Adjustments up to 6000N
To handle higher loads, the gear ratio is increased. Consequently, the actuator reaches 5mm/s without load and up to 3mm/s under load.
4. Additional components and options
The JC60DN linear actuator is standardly equipped with a cable with a plug. The plug is used for connecting to a control box. The control box allows multiple cylinders to be controlled simultaneously, and a manual operator can be attached as well. This enables simple applications to be adjusted via manual control. It should be noted that synchronous operation cannot be achieved with this setup. Despite starting the lifting movement of multiple actuators simultaneously, they do not necessarily move at the same speed.

5. Typical applications
Linear actuators are used in a variety of applications where protection against dust and water is crucial.
Here are some typical application areas:
Industrial facilities
In industrial automation, IP66 linear actuators are frequently used to control movements in machines and systems. They provide protection against dust and splash water in factories and production environments.
Food processing
In the food industry, especially in wet and cleaning areas, IP66 linear actuators are essential. They can be used in conveyor systems, packaging machines, and other applications.
Environmental technology
In outdoor applications, such as wastewater treatment plants, pumping stations, and sewage treatment facilities, IP66 linear actuators are required to protect the electronics from rain and environmental factors.
Farming
In agriculture, IP66 linear actuators are used in tractors, harvesters, and irrigation systems to ensure they can withstand the challenges of dusty and wet environments.
Medical technology
In medical equipment, especially in surgery and diagnostics, precise actuators are required that are resistant to cleaning and sterilization procedures.
Marine applications
In shipping and marine applications, IP66 linear actuators are used in various systems, including controls for ship cranes, hatches, and valves.
Building industry
In construction machinery and equipment that operate outdoors and in dusty environments, IP66 linear actuators are necessary to protect the electronic components.
Energy sector
In power generation, particularly in hydroelectric plants, IP66 linear actuators are used to control gates and valves.
6. Pro and Cons
Cons
✘ Cost: JC60DN linear actuators are generally more expensive than non-protected models, as they require special seals and construction.
✘ Weight and Size: The additional protective measures can increase the weight and size of the linear actuator, which may be a disadvantage in cases of limited installation space.
Pros
✔ Dust Protection: Linear actuators JC60DN are dust-tight and provide reliable protection against the ingress of solid particles such as dust and dirt. This is advantageous in dusty work environments or heavy industry.
✔ Water Protection: They are waterproof and can withstand high-pressure water jets or splashes. This is particularly important in humid or wet environments or outdoor applications where rain is a factor.
✔ Reliability: The protection against environmental influences offers high reliability and a longer lifespan for the electronic components.
✔ Versatility: They can be used in a wide range of industries and applications, including industrial automation, food processing, environmental technology, and more.
✔ Safety: By being protected from moisture and dust, they contribute to the safety of equipment and machinery and reduce the risk of malfunctions or failures.
FAQs about Linear Actuators
What types of linear drives are there?
There are mechanical, electromechanical, direct electric linear actuators (linear motors), as well as hydraulic and pneumatic linear actuators. We utilize electromechanical actuators in our drive solutions.
Which types of linear drive technology there are - GROB GmbH chevron_rightHow do electromechanical linear actuators differ from hydraulic or pneumatic ones?
Electric linear drives use electrical energy for motion, whereas hydraulic and pneumatic drives use fluids or gases. Electric drives are more precise and efficient.
Can I attach my own motor to the cylinder?
No, the MINI and linear cylinders are complete systems and cannot be expanded with other motors.
What does the IP66 protection class mean for actuators?
The IP66 classification indicates that the actuator is dust-tight and protected against strong jets of water. Ideal for applications requiring robust protection.
What's a linear actuator?
A linear actuator converts rotational motion into linear motion. It is powered by electric motors. However, linear movements can also be achieved through hydraulic or pneumatic actuators. Electric linear actuators are used for more precise movements.
In what environments are actuators with IP66 useful?
Actuators with IP66 are suitable for harsh environments such as industrial settings, outdoor use, or applications requiring water cleaning.
Do actuators with IP66 require additional maintenance?
The IP66 protection class significantly reduces the ingress of dust and water, minimizing maintenance requirements. However, regular inspection is advisable.
What options for spindle mounting (head variants) are available for spindle drives?
For the spindle end, the standard range offers options including threaded end, articulated head, ball joint head, flange plate, bearing flange plate, and pin. You can find corresponding dimensions in the General Catalog 2023 (grob-antriebstechnik.de)
How does the linear actuator work?
Typically, it's an electric linear drive. It consists of three main components: spindle, motor, and gearbox. When a signal is received, the motor converts electrical energy into mechanical energy, moving the gears of the gearbox. These rotate the spindle, causing the spindle nut to move outward or inward.
What are linear actuators used for?
Linear actuators are ubiquitous: in homes, offices, hospitals, factories, agricultural settings, and many other places. In hospitals and medical centers, you'll find linear actuators used to adjust patient tables, hospital beds, or operating tables. Other applications are in industry, agriculture, construction, and industrial automation.
