EAI Oil Seal 48mm x 62mm x 8mm TC Double Lip with Spring Metal Case

Description

Product Overview

The EAI TC double‑lip oil seal is engineered for demanding rotary applications where reliability and durability are non‑negotiable. Measuring 48 mm inner diameter, 62 mm outer diameter, and 8 mm thickness, the seal incorporates a robust carbon‑steel spring that maintains constant pressure on the sealing surfaces, eliminating the risk of back‑off under high‑speed rotation. The outer cover is molded from 70A Nitrile Butadiene Rubber (NBR), a material known for its excellent resistance to oil, grease, and a wide range of hydraulic fluids, while also providing a low‑temperature flexibility that keeps the seal functional down to –40 °F.

Beyond material selection, the double‑lip design adds an extra barrier against contaminants, ensuring that dust, water, and other particulates are kept out of the shaft bore. The internal metal case protects the spring from corrosion and mechanical wear, extending service life even in harsh industrial environments. This combination of a steel spring, nitrile coating, and double‑lip architecture makes the seal suitable for automotive engines, motorcycle crankshafts, differential assemblies, camshafts, axle shafts, water pumps, and a variety of other machinery where sealing integrity is critical.

Usage

Designed for both automotive and industrial sectors, the EAI oil seal excels in applications that involve high pressures, temperature extremes, and exposure to aggressive fluids. In automotive contexts, it is commonly installed on crankshafts, camshafts, and transmission components where it prevents oil leakage and protects bearings from contamination. In industrial settings, the seal is used on hydraulic cylinders, pneumatic actuators, and pump shafts, providing a reliable barrier against mineral oil, petroleum products, and synthetic hydraulic fluids.

The seal’s temperature tolerance of –40 °F to 226 °F allows it to operate in cold‑climate environments as well as in high‑heat zones such as engine bays and heavy‑duty equipment. Its resistance to hydrocarbon fluids means it can be employed in marine applications, agricultural machinery, and construction equipment where exposure to fuel and lubricants is routine. Installation is straightforward: the seal fits into a standard groove on the shaft, and the spring automatically expands to maintain contact, reducing the need for additional retaining hardware.

FAQ

What size shaft does this seal fit?

The seal is designed for a 48 mm inner diameter shaft, with an outer diameter of 62 mm and a thickness of 8 mm, fitting standard groove dimensions used in many automotive and industrial applications.

Can this seal be used with hydraulic fluid?

Yes, the nitrile rubber coating provides excellent resistance to hydraulic fluids, mineral oil, and petroleum‑based lubricants, making it suitable for hydraulic cylinder shafts and pump assemblies.

How does the double‑lip design improve performance?

The double‑lip configuration creates two sealing barriers, which significantly reduces the chance of fluid leakage and prevents contaminants from entering the shaft bore, enhancing overall system reliability.

Is there a warranty or guarantee?

All EAI oil seals come with a limited warranty covering material defects and manufacturing errors. Our support team will work with you to resolve any issues that arise within the warranty period.

What maintenance is required for the seal?

Regular inspection of the seal for wear, cracks, or deformation is recommended. Replace the seal if any damage is observed to maintain optimal sealing performance and prevent equipment failure.
