The Planetary Carrier Lock Plate is designed to prevent the carrier from rotating. The Carrier is part of the transmission that holds the planet gears, and if it were to rotate, it would cause the gears to come out of mesh, and the Transmission would not work properly. It helps to prevent the planet gears from coming out of the mesh.Attributes:• Helps to reduce vibration and noise in the transmission• Provided with 2 mounting holes to fit the fastener of size M10• Withstands a high level of shear force without deformationApplications:The Planetary Carrier Lock Plate helps to distribute this force evenly between the gears, which helps to prevent them from breaking or wearing out prematurely.
