These are translucent pale yellow polyurethane hollow tubes (PU bushes), cast polyurethane material, also known as urethane elastomer / wear-resistant pu tube.
The products are cylindrical hollow sleeves with smooth inner and outer surfaces, high gloss. They feature excellent wear resistance, high tensile strength, good shock absorption and anti-tear performance.
Custom sizes (outer diameter, inner diameter, length) are available. Widely used as wear sleeves, buffer bushes, shaft sleeves for machinery, mining, agricultural equipment and industrial transmission parts.
Superior Abrasion & Wear Resistance
Polyurethane material has outstanding wear resistance, far better than ordinary rubber and plastic. It can withstand long-term friction to extend service life greatly.
High Tensile & Tear Strength
Great mechanical toughness, resistant to tearing, deformation and cracking under heavy load. It maintains stable performance under repeated impact.
Good Shock Absorption & Vibration Damping
Excellent elasticity to buffer impact, reduce vibration and noise during equipment operation, protect mating mechanical parts.
Oil & Chemical Resistance
Resistant to oil, grease and many common industrial chemicals. Not easy to swell or corrode in oily working environments.
Smooth Surface
Smooth inner and outer surfaces, low friction coefficient. Reduce friction resistance in sliding applications.
Customizable Dimensions
We can customize outer diameter, inner diameter and length according to customers’ drawings or samples to match different equipment requirements.
Wide Hardness Range Available
Multiple hardness options to meet different working demands, from soft buffer sleeves to heavy-load rigid bushings.
Anti-Aging Performance
Good anti-aging property, stable physical properties for long-time continuous working.
Our polyurethane hollow tubes can be machined into various wear-resistant bushings, sleeves and buffer parts. They are widely applied in industrial machinery, mining equipment, conveyor systems, automotive industry, hydraulic & pneumatic systems, agricultural machinery and packaging machinery. They serve as shaft sleeves, wear liners, buffer sleeves, roller sleeves and anti-abrasion protective components for heavy-load and friction working conditions.
