Sintered Oil-Embedded Bearing F339 for Electronic Throttle | Low Friction and Low Temperature Noise Countermeasures
Sintered oil-containing bearings that address low friction for electronic throttle motors and noise reduction during low-temperature starts.
In automotive motors such as electronic control throttles, in addition to low friction, stable operation at room temperature and noise reduction during low-temperature starts are required. When selecting copper-based materials to enhance performance, balancing material costs can also be a challenge. Daiamet's F339 is a sintered oil-bearing bearing made from iron-copper-based material that increases the copper area ratio of the bearing inner diameter surface without increasing the copper content. It improves friction characteristics compared to the conventional material F336. ■ Material Design Supporting Low Friction ▼ Improved copper area ratio on the surface from the conventional 20-50% to over 80% ▼ Strengthened copper alloy phase with uniform dispersion of graphite in the matrix ▼ Improved static and dynamic friction characteristics at room temperature ■ Performance Required for Automotive Motors ▼ Suppression of startup noise at low temperatures ▼ Material design targeting the sliding characteristics of copper-based materials using iron-copper-based materials ■ Application Examples ▼ Electronic control throttle motors ▼ Power seat motors, EPB motors This can be utilized for selecting bearings for automotive motors that prioritize friction characteristics and quietness during low-temperature starts.
