"SM-5" is a material that conforms to JIS standards and is widely used for mechanical structural components. Post-processing can include steam treatment and carburizing quenching and tempering. Carburizing quenching refers to a heat treatment process that diffuses carbon into a metal with a low carbon content to create a hardened layer in the material. By performing carburizing quenching, the material can be hardened, improving its wear resistance. [Features] - Equivalent to the old JIS SMF5030 material - A material that conforms to JIS standards, widely used for mechanical structural components - Post-processing can include steam treatment and carburizing quenching and tempering *For more details, please refer to the related links or feel free to contact us.

• Other metal materials

"SM-4" is a material that conforms to JIS standards and is widely used for mechanical structural components. Post-treatment options include steam treatment and carburizing quenching and tempering. Steam treatment involves heating iron-based materials (or iron-copper alloys with low oil content) in water vapor at temperatures between 400 and 600°C, resulting in the formation of black magnetic iron oxide (Fe3O4) on the surface and through pores. This oxide film enhances the hardness of the product surface and improves wear resistance and corrosion resistance. 【Features】 - Equivalent to the old JIS SMF4030 material - A material that conforms to JIS standards, widely used for mechanical structural components - Post-treatment options include steam treatment and carburizing quenching and tempering *For more details, please refer to the related links or feel free to contact us.

The "FCS-20G" is an oil-impregnated bearing material that disperses free graphite powder in a pearlitic iron matrix. By dispersing graphite powder with an average particle size of 40μm, it enhances anti-seizure properties and lubrication. Additionally, through special sintering, the iron structure is transformed from ferrite to pearlite, increasing the surface hardness of the iron and improving wear resistance, making it suitable for high-load applications (low speed, oscillation, high load) with a PV value of 150 MPa·m/min or more. 【Features】 ■ High-load applications ■ Disperses graphite powder with an average particle size of 40μm, enhancing anti-seizure properties and lubrication ■ Transforms the iron structure from ferrite to pearlite through special sintering ■ Increases the surface hardness of the iron, improving wear resistance *For more details, please refer to the related links or feel free to contact us.

• Metal bearings

"CF Metal" is a special bearing that reduces noise in low and high temperature ranges. By embedding carbon fiber into the bearing and protruding part of the bearing surface, it prevents contact between the metal of the shaft and the bearing, reducing noise under operating conditions where oil film formation is difficult at low temperatures (-40°C) and high temperatures (120°C). It can be used for drive motors in transport applications such as ice cream vending machines, as well as for automotive electrical motors in general. [Recommended Usage Range] ■ Allowable PV value (MPa·m/min): 100 ■ Pmax (MPa): 2 ■ Vmax (m/min): 110 *For more details, please refer to the related links or feel free to contact us.

• Metal bearings

"LF Metal" is a bearing that improves low friction coefficient and quietness in low temperature ranges. Due to the oil-repellent properties of fluororesin, it is effective in operating conditions where oil film formation is difficult, and when you want to reduce the friction coefficient and enhance quietness in low temperature ranges. It retains oil holes due to a special coating, allowing it to be used just like a standard oil-impregnated bearing. 【Features】 ■ A coating of a film synthesized from low-friction fluororesin and metal on the bearing surface ■ It can be used like a standard oil-impregnated bearing because it retains oil holes due to the special coating *For more details, please refer to the related links or feel free to contact us.

• Metal bearings

The "FCS-200A" is a general-purpose iron-copper bearing material that can withstand relatively high loads. As a VA material, it can be used in a wide range of applications, and adding phosphorus (P) to the material composition improves hardness. Moreover, it has a high proportion of iron components that are effective for wear resistance, but since the sliding surface contains bronze components, it achieves low friction and improved quietness. 【Features】 ■ Can extend the lifespan of bearings ■ The sliding surface contains bronze components, resulting in low friction and improved quietness *For more details, please refer to the related links or feel free to contact us.

• Metal bearings

The "FCS-500" is a bearing material coated with bronze on the surface of iron powder. By finely grinding the raw material powder particles and extending the retention time of the impregnating oil, it is possible to prolong the lifespan of the bearing. Furthermore, while it has a high proportion of iron components effective for wear resistance, the sliding surface consists of bronze components, which improves low friction and quietness. 【Features】 ■ It is possible to extend the lifespan of the bearing. ■ The sliding surface consists of bronze components, resulting in low friction and improved quietness. *For more details, please refer to the related links or feel free to contact us.

• Metal bearings

"No.1-HG" is a raw material that adds graphite to a general-purpose copper-based bearing material. Under low-temperature conditions, it becomes difficult for the impregnated oil to seep out from the pores, making it a challenging environment for oil-impregnated bearings. This product disperses graphite, a solid lubricant, within the raw material powder to reduce metal contact during sliding and improve durability under harsh conditions. 【Features】 ■ Equivalent to JIS P4023Z material ■ Disperses graphite, a solid lubricant, in the raw material powder ■ Reduces metal contact during sliding and enhances durability under harsh conditions *For more details, please refer to the related links or feel free to contact us.

"No.1-H" is a material that is soft and excels in quietness. Due to its softness and ease of adaptation to shafts, it is suitable for applications that dislike sliding noise generated by motors in acoustic devices and cameras. Additionally, being a Cu-Sn alloy, it is effective in addressing rust concerns associated with Fe-based materials. 【Features】 ■ Equivalent to JIS P4013Z material ■ Soft and easily adapts to shafts ■ Effective in addressing rust concerns associated with Fe-based materials *For more details, please refer to the related links or feel free to contact us.
