The Oiles 250 series are bearings made of special cotton cloth based phenolic impregnated with lubricating oil and lubricant. ¡ Reduces the frequency of lubrication. ¡ Maintains oil fi lm, resulting in improved wear resistance. ¡ Has superior foreign matter immersion characteristics, impact resistance, and noise suppressing characteristics. ¡ Has superior chemical resistance and corrosion resistance. ¡ Materials for machining are also available. Plastic bearings especially designed for underwater applications The Oiles 425 series are bearings especially designed for water lubrication made of phenol resin with special cotton cloth base material equivalent to the Oiles 250, which is treated with special processing. ¡ Has superior foreign matter immersion characteristics, impact resistance, and noise suppressing characteristics. ¡ Has superior wear resistance, chemical resistance, and corrosion resistance. ¡ Usable in water or chemicals. ¡ The 250 material for machining may be used. Contact us about the handling methods. ¡ Certifi ed according to NIPPON KAIJI KYOKAI as the material of Nonmetallic rudder bearing.(Approval No.NKBR022, Validity Period: Oct.2017) Demonstrates superior creep resistance and wear resistance under high-load conditions. The Oiles Fiberfl on FW series incorporate polytetrafl uoroethylene (PTFE) fi bers and new-material fi bers on the friction surfaces. The load-bearing back layer consists of highly strong epoxy resin with glass fi bers. ¡ Serviceable without the need for lubrication. Offers superior performance under high-load, low-speed conditions. ¡ Tolerates abrasive friction conditions. Also usable under fretting sliding conditions. ¡ Has superior chemical resistance. ¡ Conforms to the Food Sanitation Act. ¡ The standard products are available in various sizes.
