Thin Thrust Needle Bearing for Planetary Gear Side
Use of the world’s smallest rollers (diameter of 1 mm × 1.8 mm length, for planetary gears) means the measurements of peripheral components can remain unchanged as much as possible and enables replacement from the washer. We reduced the bearing torque by at least 70% compared to the washer. We also reduced the weight by about 50% by using plastic cages.
