Plastic Bearings for Transporting Hoop Materials (Coil Materials)

This product is a specially shaped bearing with a flat groove on the outer diameter and an extended inner ring on one side. The groove shape can be custom-made to match the transported material. Can be used without collars when multiple bearings are installed in parallel. Excellent chemical resistance allows usage even in highly corrosive chemical solutions. The outer diameter section features a flat groove, enabling a custom-made design tailored to the size of thin metal sheets (hoop materials). This flat groove ensures precise guidance of the transported material, preventing scratches and damage. In addition to thin metal sheets (hoop materials), various groove shapes such as V-grooves and R-grooves can[…..]

Self-aligning Plastic Bearings for Film Sheet Transport Rollers (Dual-layer Structure)

These are self-aligning bearings used for transporting film sheets. Since the rollers are fully submerged in liquid, there was an inquiry regarding whether it would be possible to use bearings made of materials with chemical resistance, such as plastic or ceramic. The layout of the transport line can be imagined as follows: Initially, the design called for radial bearings, but because the film sheet’s tension could cause slight bending in the rollers, we proposed self-aligning bearings to ensure proper alignment even when deflection occurs. However, standard self-aligning bearings exceeded the permissible load, so we enhanced load-bearing capacity with the dual-layer structure shown in the image. In film sheet transport lines[…..]

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[…..]

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[…..]

Deep-Groove Plastic Ball Bearings for Electroplating Equipment
