Features

・Strong structure achieved by press-fitting assembly of plate and flanged collar, and by insertion into hub.
・Stronger axial joint torque achieved by using larger clamp bolts.
・You can choose high-durability carbon plate for cases where misalignment (parallel and angular misalignments, end play and vibration) cannot be restrained to low levels.
