RHC Series Cylinder Seal Kit with NBR Seals for 20mm to 100mm Bore Sizes in High Power Pneumatic Applications

Product Description:

These cylinder seal kits are precision-engineered replacement sets specifically designed for the maintenance and overhaul of RHC series high power pneumatic cylinders. They accommodate bore sizes ranging from 20mm up to 100mm. Each kit contains all the essential sealing components needed to perform a complete cylinder rebuild, including the cushion seal, piston seal, wear ring, cylinder tube gasket, rod seal, and O-rings.

The seals included in these kits are crafted from premium materials such as NBR (nitrile rubber), special resin, and urethane. These materials ensure outstanding durability and reliable performance across a broad spectrum of industrial pneumatic applications. The RHC series cylinders themselves are designed for high-speed and heavy-load operations. They feature an extended cushion design that effectively stops heavy or fast-moving loads while retaining the simplicity of a standard air cushion cylinder. Additionally, each kit provides a 10g grease pack to guarantee proper lubrication during installation.

Regularly replacing seals with these kits helps restore the original performance of your cylinders, prevents air leakage, and significantly extends the service life of existing actuators—all at a fraction of the cost of purchasing new cylinders. These seal kits are compatible with both RHCL and RHCB series high power pneumatic cylinders.

Note: Item 21, the piston gasket, is considered a non-replaceable component and is therefore not included in the seal kit.

Features:

The Complete Seal Kit offers everything needed for a comprehensive cylinder rebuild. Each set contains a cushion seal, piston seal, wear ring, cylinder tube gasket, rod seal, and various O-rings, ensuring no component is left out during maintenance.

This kit is available for a wide range of bore sizes, including 20mm, 25mm, 32mm, 40mm, 50mm, 63mm, 80mm, and 100mm cylinders. Whether you are repairing a small or large bore, there is an option suitable for your application.

Manufactured from high-quality materials such as NBR (nitrile rubber), special resin, and urethane seals, these components provide outstanding resistance against wear, compression set, and the common types of pneumatic media encountered in typical industrial environments.

Designed to meet the demands of high power applications, the seal kits are fully compatible with RHC series cylinders that exhibit ten to twenty times the energy absorption capacity compared to standard general-purpose cylinders.

Each kit also includes a 10-gram grease pack to facilitate proper lubrication during installation, helping ensure smooth operation and long-lasting performance.

By replacing worn seals, the kit effectively eliminates internal and external leakage within the cylinder, restoring the original force output and operational speed to like-new conditions.

These seals are suitable for high-speed applications, supporting cylinder speeds up to 3000 mm/s under light to medium load conditions.

This maintenance solution is cost-effective, providing a significantly lower cost alternative to purchasing a new cylinder, while extending the service life of your actuator.

Installation is quick and straightforward, designed for easy replacement using standard tools, which reduces downtime and labor costs.

The seal kits operate reliably within a temperature range from -10°C to +70°C, making them versatile for various environmental conditions.

For inventory management convenience, one unique kit number corresponds to each bore size, simplifying the stocking process for maintenance teams and suppliers.

Support and Services:

Our Pulse Valve Diaphragm is engineered for durability and optimal performance in a variety of industrial applications. To ensure the longevity and reliability of your pulse valve diaphragm, it is important to follow proper installation, maintenance, and troubleshooting procedures.

Installation: Before installation, verify that the diaphragm is the correct model for your valve. Ensure that all mating surfaces are clean and free from debris. Carefully position the diaphragm to avoid any folds or twists, and secure it according to the manufacturer’s guidelines to prevent leaks and ensure proper operation.

Maintenance: Regular inspection of the diaphragm is recommended to detect any signs of wear, cracking, or deformation. Depending on the operating environment and frequency of use, replacement intervals may vary. Always use genuine replacement parts to maintain system integrity and performance.

Troubleshooting: If you experience issues such as poor valve response, air leakage, or inconsistent pulse performance, inspect the diaphragm for damage or improper installation. Replace the diaphragm if any defects are found. Additionally, verify that the valve assembly and associated components are functioning correctly.

For optimal service life, avoid exposure to incompatible chemicals, extreme temperatures, and mechanical stresses beyond the diaphragm’s specifications. Adhering to these guidelines will help maintain the efficiency and reliability of your pulse valve system.

Packing and Shipping:

Each Pulse Valve Diaphragm is carefully packaged to ensure maximum protection during transit. The diaphragm is first placed in a protective plastic sleeve to prevent dust and moisture exposure. It is then securely positioned within a custom-molded foam insert to avoid any damage from impact or vibration.

The packaged diaphragm is enclosed in a sturdy cardboard box, clearly labeled with product information and handling instructions. Multiple layers of packaging materials are used for bulk orders to ensure the integrity of each unit throughout the shipping process.

We offer reliable shipping options with tracking capabilities to provide timely delivery and peace of mind. All shipments are handled with care to maintain the quality and performance of the Pulse Valve Diaphragm upon arrival.
