Guide Bearings for the Cleaning and Transportation of Retort Packages

Our 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 to[…..]

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.

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.

Thrust Bearings in the Waterbed

Our plastic thrust bearings were used in a waterbed with a massage function. The waterbed is rotated by the force of the water jet, creating a spiral water flow that is used for the massage. The bearings are used in the nozzles. Since it is used exclusively underwater, this environment is very suitable for plastic bearings. Water acts as a substitute for lubricant and helps dissipate the heat generated by rotation. Therefore, a longer lifespan can be expected compared to use in dry environments.

Plastic Bearings in the Cleaning Process of Ampoules

Our bearings were utilized for the ampoule cleaning process. Initially, two miniature plastic bearings from other manufacturers were used to avoid the wear of metal powder. However, wear problems also arose with the plastic bearings, leading to difficulties. One of the reasons was the strength of the plastic material, but the fact that they were standard products also led to dimensional interference and accelerated wear. Therefore, we proposed using PEEK bearings with a multi-row configuration tailored to the device’s dimensions, which resolved the issue. In our case, the multi-row configuration that combines both bearings is more cost-effective than using two separate bearings. Related Pages ・Ball Bearings ・Custom-made Ball Bearings ・PEEK[…..]

Plastic Bearings for Glass Cleaning Lines

Our bearings were used on conveyor belts for glass products. The use of metal bearings when cleaning ground glass results in water contamination due to lubricating grease. Worse yet, glass particles reduce bearing lubrication, leading to increased wear on the bearings and higher production downtime. To eliminate the problem, we offered our plastic bearings. The bearing dimensions are designed according to the current machine equipment to avoid design changes to the machines. Future design changes, such as longer shafts, are also individually accommodated by us. In the specific example, a self-aligning ball bearing was used. This allowed us to ensure maximum flexibility of the shaft. Thus, changes in shaft length[…..]

Ready-to-Install Bearing Guide Roller for the Galvanizing Plant

One of our customers has used our bearings in their galvanizing plant for wire material. Previously, this customer had used plastic plain bearings, but they frequently encountered issues such as high rotational resistance, damage, and wire breakage. After reviewing the operating conditions and shapes, we designed a roller shape that is tailored to the wire. Additionally, we combined various plastic materials for the outer ring, inner ring, and cage, and proposed a roller bearing with an integrated ball bearing. As a result, there were no concerns about the penetration of the galvanizing solution, and the need for frequent maintenance was eliminated. Downtimes due to wire breakages and quality issues caused[…..]

Plastic Bearings for Cleaning with Hydrofluoric Acid

This is a plastic bearing that can be used for hydrofluoric acid cleaning of semiconductors and LCDs. We are the only company in Japan that manufactures ball bearings from PCTFE (Polychlorotrifluoroethylene). Plastic Bearings for Cleaning with Hydrofluoric Acid Our bearings have a specification of PCTFE (Poly Chloro Tri Fluoro Ethylene) for the main body and SiC (Silicon Carbide) for the balls. Hydrofluoric acid, used in the cleaning of semiconductors and LCDs, corrodes many metals, plastics, and ceramics. We manufacture PCTFE bearings that are resistant to hydrofluoric acid. PCTFE: Poly Chloro Tri Fluoro Ethylene (Polychlorotrifluoroethylene) is a hard plastic that has proven to be particularly resistant to hydrofluoric acid. Depending on[…..]

Plastic Bearings for Toluene Cleaning

One of our customers has chosen our plastic ball bearings for the film transport roller shafts. Race ring and cage: PEEKBalls: Aluminum oxide ceramic After using the equipment, metallic bearings corrode in a short period when cleaned with chemicals such as toluene. Although other plastic materials can be used with these chemicals, we chose PEEK due to slightly increased load. As you can see, not only chemicals but also other conditions such as load, rotation speed, and temperature are involved in the material selection process. If you are considering the use of plastic bearings, please contact us. Related Pages ・Deep-groove Ball Bearings ・Chemical Environment ・Cleaning Machines Back to[…..]

Pillow Block Bearings for Cleaning with Sodium Hypochlorite

Our pillow block bearings are used in the bearings of the vegetable cleaning equipment. Housing: Stainless steel Bush: UHMWPE (Ultra-high-molecular-weight polyethylene) Sleeve: SUS304 Since the unit is used in a tank with sodium hypochlorite, it would quickly rust if conventional pillow block bearings were used. Therefore, you have opted for our plastic pillow block bearings. These do not require lubrication and there are no worries about rust or corrosion. Depending on the operating conditions, bush materials such as PTFE or phenol may also be better suited. We can make material suggestions based on your operating conditions. Furthermore, the production of bushes with special shapes, such as groove machining in the[…..]
