Уплотнительное кольцо, 1,78 x 6,07 мм Caterpillar 8I3878

The Parking Brake Disc Bolt Spring O Ring Seal creates a sealing and tensioning interface within the parking brake disc assembly. It works by forming a tight seal around the bolt area while allowing controlled compression under load. The spring action applies consistent pressure, ensuring the sealing ring remains properly seated during brake engagement and release. This arrangement prevents fluid or lubricant escape while also blocking the entry of dust and debris. The combined bolt, spring, and O-ring configuration allows movement without compromising sealing integrity. During repeated brake cycles, the component absorbs slight variations in force and maintains uniform contact.Attributes:• Blocks external contaminants from entering the sealing area.• Maintains sealing contact even under vibration conditions.• Reduces risk of pressure loss during prolonged brake application.Applications: The Parking Brake Disc Bolt Spring O Ring Seal is used within the parking brake disc assembly to provide sealing and controlled tension at the bolt interface, ensuring stable brake holding performance and preventing leakage during operation.
