The importance of mechanical seals in industrial robots

Technology has brought a blessing: the fields of electrical and mechanical engineering have experienced unprecedented growth. The industry is producing innovations never thought of before, and we are entering a new era of technological advancement.

One such technological development is industrial robotics. Industrial robotics refers to the production of robots to work on assembly lines. They can automate many menial jobs and increase efficiency. Industrial robots market is growing at about 10 percent per year.

Due to its immense importance in the industry, assembly line robots must have flawless designs. Even minor issues with manufacturing robots can lead to the collapse of the entire supply chain.

To make industrial robots, you must use the best materials, from mechanical seals for locomotives. Read about the importance of using high-quality mechanical seals in industrial robots.

How do mechanical seals work

A mechanical seal is a method of containing fluids inside a machine and preventing them from leaking. When the rotating shaft passes through a stationary case, there is a possibility that internal fluids will leak, and this can prevent sealing.

When the rotating shaft enters the fluid chamber, the sealant causes friction. Mechanical seals should allow the shaft to operate with minimal friction while stopping the leak.

When you seal the fluid chamber, it will cause pressure on the seal. A viable mechanical seal must also be able to withstand this stress.

Traditionally, this problem was overcome by mobilizing the gland. It included filling the shaft with a rope-like braided material to prevent fluid leakage. However, the coating wears out over time and needs to be readjusted.

The filler must also be pressed against the shaft to reduce leakage, which causes the pumping device to expend more energy to rotate the shaft. Mechanical seals are better suited to industrial robots to reduce the need for maintenance and energy.

Choosing the right mechanical seal for industrial robots

Bots do not include only correct Maths But also high-quality building materials. Several factors can affect the type of mechanical seal you should buy for your robot:

Friction balance and sealing efficacy

Effective sealing may lead to friction, and reducing friction will require compromising the quality of the seal. Robotics have to find the right compromise between friction and seal efficacy.

They allow just enough leakage that keeps friction under control, while forming a vapor film over the seal. Reducing friction is especially important as the robot must perform repeated minute moments. Consider your calculations and decide how many effective seals you need.


Mechanical seals are subject to wear and tear. Due to the friction between the seal and the shaft, the seals wear out over the years. Industrial robots are made for long-term purposes, so they must have durable mechanical seals.

The sealing material can affect its durability. Seals are made of Polytetrafluoroethylene (PTFE) is suitable for robots, as it resists degradation and provides low-friction performance, even with aggressive engines. And they do not need lubrication. These features ensure that they last longer and make them ideal for industrial robots.

Final Comment

Robots have changed our economy for the better. Automation of the assembly line has increased the efficiency of goods production, allowing us to make more goods at lower prices. Industrial robots must be durable and of high quality to ensure smooth operation.

Premium materials were used in the manufacture of such robots. Consider using a durable mechanical seal from a reputable company, depending on your sealing requirements, such as a PTFE seal.
