Description
Product Overview
The EAI Oil Seal Double Lip TC model is engineered for demanding rotary applications where reliability and durability are paramount. Measuring 60mm in inner diameter, 80mm in outer diameter, and 8mm in thickness, this seal fits a wide range of shafts, crankshafts, camshafts, and axle components. Its construction features a carbon‑steel spring that maintains constant pressure on the sealing lip, while the outer cover is molded from high‑strength nitrile rubber, offering excellent resistance to oil, hydraulic fluid, and petroleum‑based contaminants.
Beyond its robust mechanical design, the seal benefits from a metal case that protects the internal spring and rubber from physical damage during handling and installation. The nitrile coating is formulated to endure temperature extremes from -40°F to 226°F, ensuring consistent performance in both cold‑start environments and high‑heat industrial processes. This combination of materials provides a seal that not only prevents leakage but also guards against ingress of dust and debris, extending the service life of the equipment it protects.
Manufactured by EAI Parts, a reputable supplier in the industrial sealing market, the TC series adheres to strict quality control standards. Each seal undergoes dimensional verification and material testing to confirm compliance with industry specifications. The result is a product that delivers predictable sealing performance, reducing downtime and maintenance costs for users across automotive, marine, and heavy‑machinery sectors.
Usage
This double‑lip oil seal is ideally suited for hydraulic systems, where it prevents fluid escape from rotating shafts while tolerating high pressures. In automotive applications, it serves as a reliable barrier for engine crankshafts, camshafts, and transmission components, protecting against oil loss and contamination. The seal’s compatibility with mineral oil, synthetic hydraulic fluids, and greases makes it a versatile choice for equipment that operates under varying lubrication regimes.
Installation is straightforward thanks to the seal’s compact metal housing, which can be pressed onto the shaft using standard tooling. The spring‑loaded design automatically compensates for minor shaft misalignments, ensuring a tight seal even under dynamic loading conditions. Users in the marine industry appreciate its resistance to saltwater corrosion, while manufacturers of water pumps and valves rely on its ability to maintain sealing integrity in wet environments.
For maintenance crews, the seal offers easy removal and replacement without the need for specialized equipment. Its robust construction minimizes the risk of damage during disassembly, and the nitrile rubber can be cleaned with common solvents if minor contamination occurs. This ease of service contributes to reduced labor time and lower total cost of ownership for facilities that require frequent equipment turnover.
