High-Load Plastic Roller Bearings for Solar Cells

Conventional plastic deep groove ball bearings use balls that rotate at a point, whereas plastic roller bearings use rollers that rotate along a line, allowing them to withstand greater loads. Currently, they are used in applications such as conveyor rollers for transporting materials in chemically-laden environments within solar cell production facilities.

Pillow Block Bearings for Conveyor Rollers in a Sludge Treatment Plant

Our special pillow block bearings were used for the conveyor rollers in the sludge treatment plant. Originally, there was a consideration to extend the lifespan because the previously used pillow block bearings were worn out by sludge. To prevent sludge from remaining in the sliding area, we made special holes along the outer diameter of the bushing to the inner diameter and milled spirals into the inner diameter. These holes serve to allow the sludge that accumulates in the inner diameter to flow through and help extend the lifespan by enabling a water solution. In fact, tests with this specification showed that wear was significantly reduced compared to before. As[…..]

Plastic Bearings in a Process for Surface Treatment of Thin Sheets

Our Self-aligning ball bearings were used in a process for surface treatment of copper sheets. Two rollers are suspended vertically, and the copper plate passes through the process by running between the rollers and being chrome-plated. Bearings were used at the top of these rollers. As the copper plate passes, the rollers tend to tilt and shift, hence a self-aligning function is required. Additionally, the rollers bear vertical loads, imposing additional requirements on the bearings. Therefore, we proposed our self-aligning ball bearings, which can accommodate this axial load. It is a special form not available in standard specifications, but we can manufacture it through CNC machining. Our company specializes in[…..]

Plastic Bearings for Extremely Cold Environments

Our bearings were used for the ice cream production line. Due to the manufacturing of ice cream in extremely cold environments and the use of cleaning agents during the cleaning process, a transition to plastic was considered. Because of the extremely low temperatures, we recommended the use of PTFE from our side. PTFE is a material that can be used even in extremely low temperatures of up to -268°C. However, it should be noted that dimensional changes occur significantly at temperatures. Therefore, it is important to consider the change in dimensions when used in high or low temperatures. Furthermore, we also offer materials that have been enhanced with fillers to[…..]

Double-Row Plastic Bearings

These bearings are used in a thread feeding line. Initially, a plastic bearing of type 6002 was used, but it could not withstand the load and led to rotational errors. Without changing the size of φ32×φ15×9L, the specification was changed from a single row to a double row, and by adding more balls, a higher load could be accommodated. In addition, by switching to an angular contact structure internally, a certain amount of axial load was also made possible. Depending on the size, it is possible to manufacture bearings with such internal specification changes.

Non-Magnetic and Insulating Bearings That Do Not React to Metal Detectors

Our plastic bearings can be used near metal detectors. To ensure that there are no metal contaminants present, we do not use metallic bearings in such locations, as they can react to metal detectors and lead to inaccurate results. Metal is detected through methods such as electrical conductivity or magnetic reaction, but plastic is generally an insulator and non-magnetic, making it useful in such specialized environments. However, some plastics can accumulate static electricity due to their insulation. Since this electrostatic charge can sometimes interfere with equipment, we recommend using bearings made of antistatic plastic in such cases. Depending on requirements, we offer solutions with various materials. Please contact us if[…..]

Plain Plastic Bearings for Liquid Seasoning Filling Machines

Our plastic bearings are used for the roller parts of conveyor chain belts in liquid seasoning filling machines. Metal parts cause rust when liquid seasoning spills onto them and sticks to the chain. This results in the chain and bearings clumping together, and since replacing the bearings alone is difficult, the entire chain had to be replaced. By switching the chain bearings to plastic, we achieved a longer lifespan. Additionally, it is now possible to easily replace only the plastic rollers, leading to significant cost savings.

Plastic Guide Bearings for the Cleaning and Transportation of Retort Packages

Our plastic bearings have been used in the process of cleaning and drying retort packages. Originally, metal bearings with a plastic coating were used. The production line for retort packages here uses tap water for cleaning and goes through a drying oven process. Due to the use of water, metal bearings face the problem of grease being washed out and rust formation. Furthermore, tap water contains calcium carbonate, so when passing through the drying oven after cleaning while still wet, calcium carbonate adheres inside the bearing, leading to faulty rotation. Therefore, we proposed the use of UHMWPE, which is non-sticky, and designed the shape of the bearings to be easy[…..]

Plastic Bearings for Conveyor Rollers in the Food Cleaning Process (Alcohol Cleaning, etc.)

This is an example of using bearings in the alcohol cleaning of kamaboko, processed fish paste. In this process, stainless steel bearings were used, but the alcohol washed out the internal grease, leading to faulty rotation. By switching to PEEK bearings, the bearings can be used without grease, eliminating concerns about corrosion or deterioration from alcohol.

Plastic Slide Bearings in a Chemical Environment

Our plastic slide bearings were used for the monitoring camera in a manufacturing process. While the manufacturing facility is in operation, the camera extends, and when the line stops, the camera retracts. Our slide bearings were used for this extension and retraction mechanism. Since this manufacturing process takes place in an environment with chemical solutions, a metallic solution would corrode quickly. Therefore, our customer considered using plastic. We suggested PEEK slide bearings from our product range. Since the shaft is made of stainless steel, we used ceramic balls.
