Automotive Oil Seal Retainer Ring

Centered mounting flange with a large inner bore and dual lateral holes serves as a rigid interface for hydraulic manifolds, pump bodies, or pneumatic actuators. The flat plate geometry provides a stable sealing surface against mating components, while the symmetrical side holes allow for bolt-down fixation to maintain alignment under fluid pressure or mechanical vibration.

Manufacturing precision focuses on the perpendicularity of the central bore relative to the mounting face and the positional symmetry of the side holes to prevent assembly stress. Critical tolerances include the flatness of the sealing surface and the concentricity between the inner diameter and outer profile, ensuring leak-free performance and uniform load distribution across the fasteners.

Weide Auto Parts leverages CNC turning and vertical machining centers to achieve tight dimensional control on such disc-shaped components, supported by CMM and image measuring instruments for verifying hole positions and surface integrity. With IATF16949 certification, the facility handles material selection from carbon steel to stainless alloys, offering heat treatment and surface coatings like zinc plating or black oxide to meet specific corrosion resistance and hardness requirements.
