Ready-to-Install Plastic 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[…..]

Phosphoric Acid Resistant Plastic Bearing

Phosphoric acid is commonly used in electroplating solutions and other applications. In phosphoric acid environments, conventional metal bearings can corrode. At Kashima Bearings, we manufacture bearings from materials resistant to phosphoric acid. These plastic bearings can be used without corrosion, leading to maintenance-free operation and longer service life. The resistance depends on the concentration and temperature, so please inform us of these details when making inquiries. Based on our experience, we can also create special material combinations tailored to your needs, even if they are not offered by other manufacturers. Additionally, depending on the load, speed, and other usage conditions, it might be advisable to use other materials. Please inform[…..]

Full Ball Type Plastic Ball Bearings Without Cages

Full-ball plastic ball bearings without a cage do not have a cage. Therefore, these bearings are used in dirty water, as contaminants do not remain in the cage. For example, they are used in a coating tank. Full Ball Type Plastic Ball bearings without Cages Usually, deep groove ball bearings have cages to retain the balls. However, in cases where they are used in chemical environments or in water with impurities, deep groove ball bearings sometimes fail because the impurities remain in the cage. Also, metal bearings cannot be used in coating tanks. But our bearings can be used in coating tanks because they do not get coated. They are[…..]

Plastic Deep Groove Ball Bearings for Transporting Inserted Plums

Rust-resistant, corrosion-resistant, ideal for production lines in food manufacturing. Safe for use in food as they are grease-free. Can be cleaned with water. Plastic deep groove ball bearings for transporting inserted plums This is a plastic deep groove ball bearing designed for transporting pickled plums. In the manufacturing process of pickled plums, salt and citric acid are used. Metallic bearings run the risk of corrosion and rust, or the potential for grease to contaminate the food. Plastic bearings, however, do not corrode even in the presence of salt and citric acid. Since no grease is used, it’s an environmentally friendly product that can be safely used for extended periods.

Plastic Bearings for Fan Rotation in a Stirring Device

In a tank with a highly acidic atmosphere, we use plastic bearings for the fan bearings. The fan runs continuously to maintain a uniform atmosphere in the tank. However, traditional bearings quickly corrode in such conditions. Therefore, we recommend using plastics with acid resistance and also incorporate balls made from acid-resistant ceramics to ensure the bearings withstand the conditions.

Acid-Resistant Plastic Bearings for Use in Highly Acidic Environments

In cleaning systems for semiconductor and LCD industries, there is an aggressive acidic atmosphere that corrodes conventional metal bearings. As a solution in such cases, plastic bearings are employed.

Plastic Bearings for UV (Ultraviolet) Environments

Typically, exposure to UV light causes a phenomenon known as UV degradation in standard plastics, which impairs their performance as ball bearings. In such environments, we select special materials suitable for your application.
