EAI 45mm x 65mm x 8mm FPM/FKM TC Double Lip Oil Seal Stainless Spring

Description

Product Overview

The EAI 45mm x 65mm x 8mm double‑lip oil seal is engineered for high‑performance sealing in a wide range of industrial applications. Constructed with a precision‑molded stainless steel spring, the seal maintains consistent contact pressure across the shaft, preventing leakage even under fluctuating pressure conditions. The sealing lips are made from a proprietary blend of FPM (fluorocarbon) and FKM (fluorocarbon‑synthetic) elastomers, delivering exceptional chemical resistance to mineral oils, fuels, acids, and a variety of aggressive solvents. This material combination also offers a broad operating temperature range, from -26°C to 230°C, allowing the seal to function reliably in both low‑temperature environments and high‑heat processes. The TC (tapered cone) design ensures a snug fit within the housing, reducing wear and extending service life. With dimensions of 45mm ID, 65mm OD, and an 8mm thickness, the seal fits standard bore sizes commonly found in hydraulic cylinders, pneumatic actuators, and gearboxes.

Beyond its core mechanical attributes, the seal incorporates a double‑lip configuration that provides a secondary barrier against contaminants. This dual‑seal approach not only improves leak protection but also simplifies maintenance by allowing the outer lip to be replaced independently of the inner sealing element. The stainless steel spring is corrosion‑resistant, guaranteeing long‑term durability even in harsh environments where moisture or corrosive agents are present. The seal’s compact profile enables easy installation in confined spaces without sacrificing performance, making it a versatile solution for OEMs and retrofit projects alike.

Usage

Designed for versatility, the EAI double‑lip oil seal excels in hydraulic and pneumatic systems that demand reliable fluid containment. It is ideally suited for use in oil‑filled gearboxes, hydraulic cylinders, and pneumatic actuators where high pressure and temperature fluctuations are common. The seal’s chemical resistance makes it a preferred choice for applications involving mineral oil, diesel fuel, synthetic lubricants, and even aggressive chemicals such as mineral acids and chlorinated hydrocarbons. In automotive and marine settings, the seal can be employed to protect bearings and shafts from seawater intrusion and salt‑induced corrosion, thanks to its stainless steel spring and fluoropolymer elastomer composition.

Industrial equipment manufacturers often select this seal for its ability to withstand continuous operation in demanding environments, such as metal‑working machinery, extrusion presses, and high‑speed spindles. The seal’s temperature tolerance allows it to be used in processes that involve heating or cooling cycles, including plastic extrusion, food processing, and pharmaceutical manufacturing, where maintaining product purity is essential. Its robust construction also makes it suitable for renewable energy applications, such as wind turbine gearboxes, where reliability and low maintenance are critical for long‑term operation.

FAQ

What is the temperature range for this seal?

The seal operates safely from -26°C up to 230°C, making it suitable for both low‑temperature and high‑heat applications.

Can this seal be used with mineral acids?

Yes, the FPM/FKM elastomer composition provides excellent resistance to mineral acids, ensuring long‑term durability in corrosive environments.

Is a replacement spring available separately?

We offer stainless steel springs as a separate part for maintenance or retrofit projects, allowing you to replace the spring without discarding the entire seal.

What is the recommended installation torque?

For optimal performance, we recommend tightening the housing to a torque of 15–20 Nm, ensuring even compression of the seal without over‑loading the spring.

How does the double‑lip design improve sealing?

The dual‑lip configuration creates a primary barrier and a secondary backup, reducing the likelihood of leakage if one lip becomes damaged or worn.
