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[…..]

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[…..]

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[…..]

Antistatic Plastic Bearing

In environments where electrostatic discharge can have significant effects, plastics with antistatic properties are selected and used. An example application is the transportation of glass plates in conveyor lines.
