US Seal PS200 Lip Seal for 5/8″ Shaft – Buna Material, 200 Series

Description

Product Overview

The US Seal PS200 lip seal is a precision‑engineered component designed to fit a 5/8 inch shaft. Manufactured by US Seal, a trusted name in sealing technology, this lip seal belongs to the 200 series and features a robust Buna rubber compound that resists wear, chemical exposure, and temperature extremes. Its compact dimensions—approximately 1 × 1 × 2 inches and weighing only 0.63 ounces—allow it to be installed in confined spaces without sacrificing sealing performance.

Designed for both hydraulic and pneumatic systems, the PS200 provides a reliable barrier against fluid escape, protecting equipment from contamination and loss of pressure. The seal’s lip geometry creates a tight, low‑friction interface that minimizes wear on the shaft while maintaining consistent sealing even under fluctuating pressures up to 3000 psi. The Buna material offers excellent resistance to oil, water, and many industrial chemicals, ensuring a long service life in demanding environments.

US Seal subjects each PS200 seal to rigorous quality‑control testing, including dimensional verification, material hardness checks, and leak‑rate assessments. The result is a product that consistently meets or exceeds industry standards for lip seals, delivering dependable performance for a wide range of applications.

Usage

The PS200 lip seal is ideally suited for hydraulic cylinders, pneumatic actuators, and rotary equipment where a 5/8 inch shaft requires a reliable sealing solution. It performs well in agricultural machinery, construction equipment, material handling systems, and OEM assemblies that demand consistent pressure retention and protection against contaminants.

Operating temperatures range from -40 °F to 200 °F, and the seal can handle pressures from low‑vacuum up to 3000 psi, making it versatile for both low‑speed and high‑speed applications. Its chemical resistance allows use with mineral oil, synthetic hydraulic fluids, and many cleaning solvents, reducing the need for frequent replacements.

Installation is straightforward: clean the shaft surface, apply a thin layer of compatible lubricant, and press the seal into the housing groove until it seats fully. Proper alignment prevents premature wear and ensures optimal sealing performance. Regular inspection during scheduled maintenance helps detect early signs of wear, extending the seal’s service interval.

Why Choose Us

US Seal has built a reputation for delivering high‑quality sealing solutions for over three decades. The PS200 lip seal benefits from the company’s extensive research and development efforts, resulting in a product that balances durability, flexibility, and cost‑effectiveness. Each seal is produced using controlled extrusion processes that guarantee uniform thickness and consistent lip geometry.

Durability is a core advantage of the PS200. The Buna compound resists cracking, swelling, and hardening, even after prolonged exposure to harsh chemicals and temperature cycles. This resilience translates into lower total‑cost‑of‑ownership for end users, as the seal can often exceed the typical service life of competing products.</n

FAQ

What shaft sizes are compatible with the PS200 lip seal?

The PS200 is specifically sized for a 5/8 inch (0.625 in) shaft. It can accommodate minor variations in diameter due to manufacturing tolerances, but it is not intended for larger or smaller shafts.

Can the PS200 be used with synthetic hydraulic fluids?

Yes. The Buna material is compatible with most synthetic hydraulic fluids, including phosphate‑ester and silicone‑based fluids. It provides reliable sealing without swelling or degradation.

What is the recommended installation procedure?

First, clean the shaft and housing groove to remove debris and old seal residue. Apply a thin coat of compatible lubricant to the shaft, then press the seal evenly into the groove until it seats fully. Verify that the seal sits flush and that the lip contacts the shaft uniformly.

How often should the PS200 be inspected or replaced?

Inspection frequency depends on operating conditions. In high‑pressure or abrasive environments, a visual check every 6 months is advisable. Replace the seal if you notice cracking, deformation, or loss of sealing performance.

Does US Seal offer any warranty on the PS200?

US Seal provides a limited warranty covering material defects for a period of one year from the date of purchase. Technical support is available throughout the warranty term to assist with any issues.
