Applications Depending on Equipment

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[…..]

High-Load Plastic Roller Bearings for Solar Cells

Conventional plastic deep groove ball bearings use balls that rotate at a point, whereas plastic roller bearings use rollers that rotate along a line, allowing them to withstand greater loads. Currently, they are used in applications such as conveyor rollers for transporting materials in chemically-laden environments within solar cell production facilities.

Plastic Bearings with Inner Stud (Threaded Hole) Specification

This is a bearing with an internally threaded hole. There are various methods to mount bearings, including attaching flanges, fixing with collars at both ends, using retaining rings, pressing into the shaft or housing, etc. For our main products, plastic bearings, the common method is to press fit the outer diameter to secure the bearing. Among these different mounting methods, as shown in the photo, it is also possible to equip the bearing with an internal threaded hole and fix it with a screw. Depending on the bearing size, it is possible to manufacture thread sizes and pitches in the dimensions you specify. If you have any issues with mounting[…..]

Plastic Bearings for Extremely Cold Environments

Our bearings were used for the ice cream production line. Due to the manufacturing of ice cream in extremely cold environments and the use of cleaning agents during the cleaning process, a transition to plastic was considered. Because of the extremely low temperatures, we recommended the use of PTFE from our side. PTFE is a material that can be used even in extremely low temperatures of up to -268°C. However, it should be noted that dimensional changes occur significantly at temperatures. Therefore, it is important to consider the change in dimensions when used in high or low temperatures. Furthermore, we also offer materials that have been enhanced with fillers to[…..]

Non-Magnetic and Insulating Bearings That Do Not React to Metal Detectors

Our plastic bearings can be used near metal detectors. To ensure that there are no metal contaminants present, we do not use metallic bearings in such locations, as they can react to metal detectors and lead to inaccurate results. Metal is detected through methods such as electrical conductivity or magnetic reaction, but plastic is generally an insulator and non-magnetic, making it useful in such specialized environments. However, some plastics can accumulate static electricity due to their insulation. Since this electrostatic charge can sometimes interfere with equipment, we recommend using bearings made of antistatic plastic in such cases. Depending on requirements, we offer solutions with various materials. Please contact us if[…..]

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.

Cam Follower Bearing Made Entirely of Plastic

This product was developed in response to the request, “Can cam followers be made of plastic?” The desire was to use plastic because metal parts could potentially cause malfunctions in a testing device. Integrating the bearing and screw reduces the number of parts and simplifies replacement. Additionally, due to the plastic material, there is no risk of damaging the workpiece. The illustrated screw sizes are M4 and M10, but manufacturing is possible regardless of the standard. Within the testing device, it is used as a guide rail for positioning as well as a transport roller over which the workpiece rolls to the next processing stage.

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[…..]

Plastic 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.
