Bearing materials that are environmentally friendly and do not use lead, which is a substance that imposes an environmental burden!
The "Daidain DDK02" is a dry bearing with excellent chemical resistance. It features a porous sintered copper-tin alloy on a steel backing, lined with a mixture of polytetrafluoroethylene (PTFE) and special fillers. It demonstrates outstanding durability under boundary and fluid lubrication conditions, combining the good sliding characteristics of PTFE and special fillers with the strength and dimensional stability of metal materials. It is possible to set a thickness of 0.5mm for small diameters (φ10 or less). This contributes to lightweight and compact designs in applications such as solenoids. 【Features】 ■ Exhibits high load capacity comparable to metal materials ■ Has low friction coefficient and wear resistance under boundary and fluid lubrication ■ Does not experience stick-slip with a low friction coefficient ■ Excellent chemical resistance ■ Equipped with cavitation resistance characteristics ■ Wide temperature range for use *For more details, please refer to the PDF document or feel free to contact us.
