Polyurethane Sleeves: Durable Solutions for Industrial Applications

As a trusted name in polyurethane solutions since 2007, Yantai Zhengyuan Polyurethane Co., Ltd. offers a full range of custom-engineered polyurethane sleeves for various industrial applications. Designed for durability and performance, our PU sleeves are used to protect, cushion, and extend the life of components in harsh working environments.

What Are Polyurethane Sleeves?

Polyurethane sleeves are hollow cylindrical components manufactured from high-grade cast polyurethane. They are typically fitted over shafts, rollers, rods, or mechanical parts to provide protection, reduce wear, and dampen vibration. Compared to conventional materials like rubber or PVC, polyurethane offers superior performance in terms of mechanical strength, abrasion resistance, and resistance to oils and solvents.

Key Applications

Material handling systems and rollers

Mining and aggregate processing equipment

Pneumatic and hydraulic systems

AGVs and forklift components

Industrial automation and logistics

Product Features

🔹 Exceptional Abrasion Resistance
Our PU sleeves are ideal for high-friction and high-cycle applications thanks to their outstanding resistance to surface wear and cracking.

🔹 Customizable Dimensions
We produce polyurethane sleeves in a wide range of sizes, thicknesses, and hardness levels (from Shore A 60 to Shore D 70), based on customer drawings or specifications.

🔹 High Mechanical Strength
The sleeves exhibit excellent tensile strength, elongation at break, and tear resistance. These properties ensure reliable operation even under heavy loads and extreme conditions.

🔹 Oil, Solvent, and Chemical Resistance
The material maintains stability and physical properties in contact with lubricants, fuels, greases, and industrial chemicals.

🔹 Good Elasticity and Resilience
Polyurethane sleeves made by Zhengyuan retain their shape and elasticity over time, offering long-term protection for shafts and components.

Manufacturing & Quality Assurance

We utilize precision centrifugal casting, compression molding, and CNC machining techniques to ensure uniformity and tight tolerances. Every product undergoes strict quality checks, including DIN abrasion testing, tensile strength, elongation, and tear resistance to guarantee performance consistency.
