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 Axial Bearings for Food Manufacturing (Processing) Equipment

Hygienic because no grease is used. Resistant to disinfectants, cleaning agents, and high temperatures, does not rust or corrode. Plastic bearings for food manufacturing facilities. Plastic axial bearings for food manufacturing (processing) equipment Typically, metal bearings are used in food manufacturing machines, which are protected from direct contact with moisture or steam by seals. Even if the bearings have a sealing structure, moisture can penetrate over time and grease can leak out. With a plastic axial bearing, the need for grease is eliminated, and it is corrosion-resistant. Therefore, there are no concerns about grease or rust getting into the food. It can be used in environments with cleaning solutions (such[…..]

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. Recommended[…..]

Integrated Plastic Bearing Sprocket (Sprocket Wheel)

Stainless, corrosion-resistant gears Integrated Plastic Bearing Sprocket (Sprocket Wheel) We manufacture gears for various applications starting from one piece. No lubrication required, hence safe and worry-free. This is an integrated plastic bearing sprocket (sprocket wheel) that can be used in environments where liquids are present, such as cleaning lines or environments where lubricants are not required. Being made of plastic, it does not rust or corrode. Additionally, it is recommended for production lines, especially in the food industry, as it does not require lubricants. We offer a variety of materials that are corrosion-resistant and can withstand high temperatures. We manufacture products that meet a wide range of requirements, starting from[…..]

Spherical Plain Bearing (Plastic Spherical Plain Bearing)

A self-aligning plain bearing that can also be used in places without a core where the core cannot be removed. Plastic Spherical Plain Bearing Spherical Plain Bearing with Stainless Steel Housing Spherical plain bearings are self-aligning bearings, particularly suitable when the shaft is long and easily deformable or when it is difficult to remove the core on the left and right sides. The size can be adjusted to various dimensions depending on the usage situation, allowing them to be used even in tight spaces where mounting a pillow block is difficult. Being made of plastic, there is no concern about rust, even in water or chemical substances. Additionally, they are[…..]

Phenolic Split Plain Bearing (Half-Split Plain Bearing: Two-Piece Bushing: Two-Piece Plain Bearing)

Phenolic Split Plain Bearing (two-piece bushing: two-piece plain bearing) that allows easy replacement of the bearing alone in hard-to-reach areas with long, heavy, or complex shafts. Phenolic Split Plain Bearing Phenolic Split Plain Bearing (also known as Half-Split Plain Bearing, Two-Piece Bushing, Two-Piece Plain Bearing, Split Metal) A plain bearing that is halved in shape. In conventional plain bearings (bushings: plain bearings), the shaft passes through the bearing. When replacing the bearing, especially if the shaft is heavy, long, or part of a complex structure, it is necessary to disassemble everything, remove the shaft, and replace the bearing, which is very labor-intensive. By using a two-piece plain bearing (bushing: plain[…..]

Pillow Block for Use in Water Treatment Plants

Currently in use in a stirring device in a water treatment plant. In an aqueous environment, regular pillow blocks tend to allow water ingress and corrode. To address this issue, we have chosen a housing made of stainless steel, a bushing made of UKB522*, and a sleeve made of stainless steel, which we are currently using. (*For detailed information on the material UKB522, please refer to the list of available products under “Plain Bearings” and “Pillow Blocks.”) Pillow Block for Use in Water Treatment Plants Related Pages ・Plain Bearings (Bushings) ・Pillow Blocks (Bearing Units) ・Water/Seawater ・Cleaning Machines ・Food Back to Case studies

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 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.
