Overview of PTFE (Polytetrafluoroethylene) PTFE (Teflon®, Polytetrafluoroethylene) is a polymer of tetrafluoroethylene, and its brand name in the United States is Teflon. Many people are familiar with Teflon due to its well-known use in non-stick coatings for frying pans. It is chemically stable and has excellent heat resistance and chemical resistance.

• Plastic bearings

UHMW (Ultra High Molecular Weight Polyethylene) is a type of polyethylene with an extremely high molecular weight, made primarily from ethylene and produced through advanced polymerization technology, resulting in a special thermoplastic resin with very high molecular weight.

• Plastic bearings

It has high chemical resistance, oil resistance, and is very strong at high temperatures. It has no insulation properties.

• Plastic bearings

Since similar resins can also be produced from phenolic compounds such as cresol, they are often referred to as phenolic resins. They have excellent insulation and non-magnetic properties, high resistance to oil and chemicals, and are also heat-resistant, although they are weak against alkalis. Considering their performance, they can be said to be relatively inexpensive.

• Plastic bearings

PCTFE has lower heat resistance and chemical resistance than PTFE, but it excels in mechanical strength and optical properties. It has good transparency and fluidity, allowing for injection molding, making it an easy-to-process resin.

• Plastic bearings

As a thermoplastic resin, it has very high heat resistance, excellent fatigue resistance, and is also superior in wear resistance, dimensional stability, and chemical resistance. It also has excellent insulation and radiation resistance, but it is a very expensive resin.

In the manufacturing machines for general food products, metal bearings are often sealed to prevent direct contact with moisture or steam. However, even with a sealed structure, moisture can eventually enter, causing the grease to leak out. With resin thrust bearings, there is no corrosion and no need for grease, so there is no worry about grease or rust contaminating the food. They can be used in environments where cleaning solutions (such as sodium hypochlorite) are used, and they can also withstand high temperatures (around 200°C). There are proven results for sizes over 200mm in diameter. This is a product that can be used safely for long periods and is also environmentally friendly. 【Features】 - Hygienic as it does not use grease - Resistant to disinfectants, cleaning agents, and high temperatures; does not rust or corrode. - Resin bearings for food manufacturing equipment *For more details, please download the materials or contact us.

Full ball type resin ball bearings do not have retainers, allowing for smooth circulation of the solution within the bearing and making it less likely for impurities to clog the structure. Additionally, in plating lines, metal bearings cannot be used because the plating adheres to the bearings themselves, but plastic bearings can be used in plating baths since they do not get coated. 【Main Applications】 ■ Environments where liquids or solutions containing impurities are present ■ Plating lines for semiconductors and electronic components, cleaning lines ■ Lines in liquids containing impurities, such as underwater ■ Food manufacturing lines where food debris is generated or oil is used *For more details, please download the materials or contact us.
