Large Diameter Plastic Ball Bearings (φ200 and above)

This is an example of our large diameter bearing. The photo shows a 6838 bearing (φ240×φ190×24L). This bearing is intended for use in a project involving a generator that utilizes water flow. Given that it will be used underwater, the customer is considering plastic materials and was searching for a manufacturer of large diameter bearings. We provided this bearing in response to their request to try out a few samples for testing purposes. We manufacture bearings through machining, so we can provide bearings in uncommon specifications starting from single units. We have experience in manufacturing and delivering bearings with an outer diameter of φ270 in non-standard dimensions. Additionally, our bearings[…..]

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[…..]

Pillow Block Bearings for Conveyor Rollers in a Sludge Treatment Plant

Our special pillow block bearings were used for the conveyor rollers in the sludge treatment plant. Originally, there was a consideration to extend the lifespan because the previously used pillow block bearings were worn out by sludge. To prevent sludge from remaining in the sliding area, we made special holes along the outer diameter of the bushing to the inner diameter and milled spirals into the inner diameter. These holes serve to allow the sludge that accumulates in the inner diameter to flow through and help extend the lifespan by enabling a water solution. In fact, tests with this specification showed that wear was significantly reduced compared to before. As[…..]

Plastic Bearings in a Process for Surface Treatment of Thin Sheets

Our Self-aligning ball bearings were used in a process for surface treatment of copper sheets. Two rollers are suspended vertically, and the copper plate passes through the process by running between the rollers and being chrome-plated. Bearings were used at the top of these rollers. As the copper plate passes, the rollers tend to tilt and shift, hence a self-aligning function is required. Additionally, the rollers bear vertical loads, imposing additional requirements on the bearings. Therefore, we proposed our self-aligning ball bearings, which can accommodate this axial load. It is a special form not available in standard specifications, but we can manufacture it through CNC machining. Our company specializes in[…..]

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[…..]

Double-Row Plastic Bearings

These bearings are used in a thread feeding line. Initially, a plastic bearing of type 6002 was used, but it could not withstand the load and led to rotational errors. Without changing the size of φ32×φ15×9L, the specification was changed from a single row to a double row, and by adding more balls, a higher load could be accommodated. In addition, by switching to an angular contact structure internally, a certain amount of axial load was also made possible. Depending on the size, it is possible to manufacture bearings with such internal specification changes.

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.
