Wiper Seal

 

Rotary  Seal   For additional models and sizes, please contact us.
Basic Functions of Rotary Shaft Seals:Retain lubricants within the system.Exclude contaminants from entering the system.Protect lubricated bearings.Withstand pressure differentials in certain applications.

Piston Seal  

Piston seals are used to create a sealed contact between the piston and cylinder. The moving piston generates high pressure on the seal, increasing the contact force between the seal and the cylinder surface. Therefore, the surface characteristics of the dynamic sealing interface are crucial for sealing performance.
 

Piston Rod Seal 

Piston rod seals and buffer seals are designed to seal the sliding motion between the hydraulic cylinder and the piston rod. Depending on the application, the sealing system may consist of both a piston rod seal and a buffer seal (commonly used in heavy-duty equipment) or only a piston rod seal.In addition to their sealing function, these components provide a thin lubricating film on the piston rod, which lubricates the rod itself and the wiper seal.

our advantage

High Quality

High-Quality Raw Materials. Our raw materials are sourced from top-tier suppliers in China, ensuring reliable quality that meets customers' usage requirements.Our PU made from MDI material featuring high strength, high toughness, and excellent chemical resistance.

Widely Used as Alternatives to International Brands. Our products serve as alternatives to globally renowned sealing brands such as Parker and Freudenberg .

Precision Turning Process. Utilizing turning manufacturing techniques, our products deliver high precision, low surface roughness, and superior sealing effectiveness.
Professionally certified through inspection procedures with SGS, ISO, and TÜV certifications.

Affordable prices,Cost-Effective

Raw Material Bulk Purchasing. Our large-scale and stable procurement volume provides better pricing for raw materials.

Rich Processing Experience. With 20 years of expertise focused on machined seal production, we achieve a high qualification rate and efficient material utilization, thereby enhancing cost-effectiveness.

Higher Customization Flexibility: Turned seals can be machined with greater adaptability to meet specific dimensional, geometric, and performance requirements.For non-standard sizes or special shapes, turning is more feasible, whereas moldedseals are constrained by fixed molds, making frequent modifications for custom needsdifficult.
Superior Dimensional Accuracy: Modern turning technology, supported by high-precision CNC machines, ensures tight tolerances and excellent surface finish, making itideal for applications demanding high sealing performance. In contrast, molded sealsmay suffer from dimensional variations due to mold wear, material shrinkage, and other process-related factors.
