Product Description

HBY Type Reciprocal Movement Buffer Rings

Product Description

HBY Type Reciprocal Movement Buffer Rings
HBY type is special shaped slit at the sliding lip that can leak back pressure eliminates the pressure between the rod packing and buffer ring. It is used in combination with rod packing to absorb the impact and fluctuating pressure at high load, to isolate high temperature fluid, and to improve the durability of the packing.

Our Hby Type Reciprocal Movement Buffer Rings are designed to meet the most demanding requirements in hydraulic systems. These buffer rings play a crucial role in protecting components and ensuring smooth operation by effectively handling shock and pressure fluctuations.

Key Features

• Exceptional Shock Absorption: Engineered to absorb the impact and fluctuating pressures at high loads. In high - stress hydraulic applications, they act as a shock absorber, reducing the stress on other components such as seals and pistons. This helps to extend the lifespan of the entire hydraulic system.
• Pressure Spike Protection: The anti - extrusion ring feature protects the rod sealing area from sudden pressure spikes. In heavy - duty operations where pressure can vary rapidly, the Hby buffer rings safeguard the integrity of the sealing system, preventing damage due to over - pressure situations.
• Unique Design for Pressure Management: The notched lip of the buffer ring allows for a pumping - back action, suppressing any pressure - trap effect. There is also a special - shaped slit at the sliding lip that can discharge back pressure, eliminating the pressure between the rod packing and the buffer ring. This intelligent design ensures optimal pressure distribution within the hydraulic system.
• High - Quality Materials: Made from premium - grade polyurethane (PU) and polyoxymethylene (POM). PU offers excellent abrasion and wear resistance, ensuring a long - lasting performance even in harsh operating conditions. POM contributes to the ring's structural integrity and resistance to deformation under high pressure. The combination of these materials makes the Hby buffer rings highly durable and reliable.
• Temperature and Chemical Resistance: Capable of operating within a wide temperature range, from [lower temperature limit, e.g., - 55°C] to [higher temperature limit, e.g., 120°C]. They are also resistant to a variety of media, including mineral - oil - based hydraulic fluids, barely flammable hydraulic fluids, water, and air. This makes them suitable for use in diverse industrial environments.

Technical Specifications

• Material: Mainly polyurethane (PU) and polyoxymethylene (POM). Some variants may have different material combinations available upon request to suit specific working conditions.
• Hardness: [Specify the hardness value of the PU if available, e.g., 90 - 95 Shore A]
• Inner Diameter Range: Available in a wide range of sizes, from [minimum inner diameter value] to [maximum inner diameter value] to fit different hydraulic cylinder and rod requirements. Please refer to the product size chart for detailed dimensions.
• Outer Diameter and Width: Corresponding outer diameter and width dimensions are provided to match the inner diameter sizes, ensuring a perfect fit for various applications.
• Working Pressure: Can withstand high working pressures, with a maximum rating of up to [X] MPa (specify the actual pressure value if available). Ideal for applications with extreme pressure peaks, such as in heavy - duty industrial machinery.
• Working Temperature Range: Operates effectively within a temperature range of [lower temperature limit] to [higher temperature limit].
• Maximum Sliding Speed: [Specify the maximum sliding speed if applicable, e.g., up to 1 m/s]

Applications

• Industrial Hydraulic Systems: Widely used in manufacturing plants, especially in hydraulic presses, where they protect the equipment from pressure surges during the pressing process. They are also used in hydraulic pumps and motors to ensure smooth operation and prevent premature wear.
• Construction Machinery: In excavators, the Hby buffer rings are used in hydraulic cylinders to absorb the shocks generated during digging and lifting operations. They help to maintain the stability and performance of the hydraulic system, reducing the risk of component failure. Similarly, in loaders, bulldozers, and other construction equipment, these buffer rings play a vital role in protecting the hydraulic components from the harsh operating conditions.
• Mining Machinery: Mining operations involve high - pressure and high - stress environments. Hby buffer rings are used in hydraulic systems of mining machinery such as drills, crushers, and conveyors. They protect the equipment from the extreme pressures and vibrations encountered in mining, ensuring reliable operation and minimizing downtime.
• Agricultural Machinery: In tractors, combines, and other agricultural equipment, the buffer rings are used in hydraulic systems to handle the shock and pressure fluctuations during field operations. They help to improve the efficiency and durability of the agricultural machinery, contributing to better productivity on the farm.

Package and Shipping

• Package: Each buffer ring is carefully packaged in a protective plastic bag to prevent damage during transportation. For bulk orders, they are further packed in sturdy cartons to ensure safe delivery. The packaging is designed to keep the product in perfect condition during transit.
• Shipping: We offer a variety of shipping options to meet your needs. For urgent orders, express shipping services such as DHL, FedEx, or UPS are available, providing fast delivery. For more cost - effective solutions, we also provide standard shipping methods. The delivery time will depend on the destination and the shipping method you choose.
