The O-ring of the dynamic seal is used for an interference fit with the shaft, thereby preventing wear on the shaft surface and eliminating energy consumption. 2. The product features a magnetic design, which uses magnetic force to keep the stationary and rotating rings in close contact at all times. Achieve zero leakage. 3. High-carbon fiber, a wear-resistant material, is used as the friction pair between the stationary and rotating rings, resulting in a low coefficient of friction. 4. The product has a compact design and is installed in the original oil seal location, requiring no modifications to the equipment. 5. The operating temperature can range from -40 to 200 degrees; special applications can be designed separately. 6. The service life is over 25,000 hours. Product parameters: Pressure resistance: 0.11 MPa; Temperature resistance: -40 to 200 degrees; Linear speed: 28 m/s; Radial runout: 0.3 mm; Axial play: 0.3 mm; Product thickness: 14 mm (minimum); Materials: Phosphor bronze, aluminum alloy, stainless steel; Seal material: NBR/FKM; Media: Water, oil, dust, gases; Applicable operating conditions: Suitable for oil supply and lubrication in chambers with full oil levels or under pressure; operating speed: 0–5000 revolutions per minute; operating temperature: -40 to 200 degrees, with temperatures of up to 350 degrees possible in special cases. Equipment such as pump bearing housings, gearboxes, speed reducers, compressor bearing housings, motors, fans, vertical speed reducers, direct-drive motors for new energy vehicles, underwater equipment, and mechanical seals for replacement pumps. 7. A labyrinth seal is a non-contact type of seal in which there are many intricate gaps between the moving ring and the stationary ring, thereby reducing leakage. It is an ideal labyrinth flow channel model. Several annular sealing teeth arranged in sequence are placed around the rotating shaft; gaps and expansion cavities are formed between these teeth. As the sealed medium passes through these intricate gaps, a throttling effect is created, thereby preventing the fluid from leaking. Main features of the labyrinth bearing isolator: it does not wear the shaft; an auxiliary sealing ring is placed between the shaft and the moving ring to generate a clamping force through the interference fit between them. There is only a narrow and tortuous gap between the stationary ring and the rotating ring; they do not come into direct contact, so there is no friction that would generate high temperatures. It can effectively prevent internal fluid leakage and stop external substances from entering the interior. Simple structure, easy to install.
