Oiles Lutech S
Oil-impregnated polyacetal bearings with fillers
Feature
󱛠
Serviceable without the need of lubrication and demonstrates superior
friction characteristics under light-load and high-speed conditions.
󱛠
Features low coecient of friction and superior speed characteristics.
󱛠
Prevents stick slips and squeak noises.
󱛠
Injection-molded and can be made in complicated shapes. Has good mass
productivity.
