"POR-6/POR-7" is an oil repellent agent made from environmentally friendly raw materials and possesses excellent heat resistance. Since it can dry at room temperature, there is no need to introduce high-temperature furnace equipment required for high-temperature curing oil repellent treatments. Additionally, because it uses a special solvent, it has improved coating properties, film uniformity, and quick-drying capabilities, which were issues with conventional water-based and alcohol-based oil repellent agents. 【Features】 ■ Stable and insoluble to most chemicals, allowing use with liquids other than oil ■ Forms an oil-repellent film with excellent heat resistance ■ Available in a convenient pen type ■ Does not use chemicals regulated by various laws such as RoHS, ELV, and REACH *For more details, please download the PDF or contact us.

"Porelight HDP" is an oil-impregnated bearing made from a special formulation primarily consisting of copper-coated iron powder, aimed at enhancing matrix strength, with a large and uniform dispersion of graphite, a solid lubricant, within it. The bearing offers improved wear resistance due to the underlying effect of iron, reduced galling by placing copper alloy on the surface, and enhanced lubrication and metal contact suppression due to the dispersion of graphite, making it possible to provide oil-impregnated bearings with excellent durability even under high loads. 【Features】 ■ High content of solid lubricant ensures excellent wear resistance under high load and low-speed conditions, resulting in highly durable oil-impregnated bearings. ■ Matrix reinforcement allows for a higher oil content compared to conventional materials (DMP). ■ The bearing surface is covered with a copper alloy, resulting in less galling with shafts compared to standard iron-copper materials, and improved corrosion resistance. ■ Compliant with ELV and RoHS standards. *For more details, please download the PDF or contact us.

"Polite DMP" is an oil-embedded bearing that enhances a copper alloy matrix by uniformly dispersing a solid lubricant, graphite, in large quantities, thereby reducing metal contact during sliding and improving durability under harsh operating conditions such as low speed, intermittent use, and high load. Due to the high content of solid lubricant, it excels in wear resistance under high load and low speed conditions compared to iron-based and conventional bronze materials, resulting in superior durability. 【Features】 ■ Being based on a copper alloy, it has less galling with shafts and offers high reliability. ■ Can also be used for oscillating motion specifications. ■ This bearing is used by press-fitting into the inner diameter of gears and pulleys and can be used under shaft fixation conditions (please consult a technician). ■ It is also possible to use it without oil in places where oil is undesirable (please consult a technician). ■ Compliant with ELV and RoHS. *For more details, please download the PDF or contact us.

"Polite CLB" is a material that has significantly increased the oil content compared to conventional materials to enhance reliability in applications that require particularly long lifespans, such as fan motors. By using a special method to create copper-coated iron powder and through special sintering, the matrix strength is improved compared to traditional bearing materials, and fine pores are created to achieve low air permeability. As a result, even with a high oil content, it provides bearing performance equivalent to conventional bearings. [Features] - High oil content improves reliability for applications requiring long lifespans. - Low air permeability allows for equivalent air permeability to conventional bearings even with high oil content, enabling comparable bearing performance and reducing oil leakage. - The bearing surface is covered with a copper alloy, providing excellent compatibility and corrosion resistance despite being iron-copper based. - The underlying material is iron, which suppresses wear progression after initial settling. - Switching from bronze-based bearings allows for cost reduction, among other benefits. *For more details, please download the PDF or contact us.
