The hydraulic oil seal exporter JR SEAL consistently focuses on designing seal products that are application-oriented, keeping pace with modern industrial advancements and continuously addressing the unique needs of customers.
Our comprehensive range of sealing solutions includes the hydraulic buffer seal, designed to absorb shocks and prevent fluid leakage in high-pressure systems, ensuring optimal performance and durability. We also provide center joint seal kit, which is crucial for maintaining the integrity and smooth operation of rotating joints in hydraulic machinery. To protect against environmental contaminants, our dust proof seal offers superior defense, extending the lifespan of your equipment. Additionally, our floating oil seal is engineered to endure extreme conditions, making it ideal for heavy-duty applications in industries such as construction, mining, and agriculture. At JR SEAL, we are dedicated to delivering high-quality, application-specific sealing products that meet the evolving demands of modern industry.
Construction equipment works under continuous load, vibration, heat and dust. Hydraulic sealing performance therefore has a direct effect on machine availability, oil consumption and planned maintenance intervals. On this page you can reach JR Seal application information in two ways: by the type of construction equipment you operate, or by the hydraulic component you need to re-seal.
Each equipment page explains the general working conditions of that machine, the hydraulic components commonly involved in sealing maintenance, and how to send matching information to JR Seal.

If you already know which hydraulic component needs to be re-sealed, start from the component instead. These pages describe the sealing function of each component and the information needed to match a replacement seal kit.
To check a possible match, send JR Seal the following information. The more complete the details, the faster a quotation can be prepared.
Equipment type and model, plus the year or series if it is known.
The hydraulic component involved, for example a boom cylinder, main pump, control valve, swing motor, travel motor, track adjuster or center joint.
Seal dimensions, or the original part number and seal kit number if available.
Drawings, photos or measurements of the original seal, including the cross-section where possible.
Required quantity, packing preference and destination port.
Please confirm the model, component and part details before ordering. JR Seal will review the information and reply with the suitable option or a request for further details.
