OEM HITACHI EX200-1 SWING DEVICE SLEW BOX OIL SEAL (OEM HI 4250326) | Tonkee®

Material: The oil seal is typically made from high-quality rubber or elastomeric materials with suitable hardness and durability to withstand the hydraulic pressures and environmental conditions encountered during excavator operation.

It must have excellent resistance to hydraulic fluids, abrasion, and temperature variations.

Dimensions: The oil seal is designed to fit precisely within the swing device assembly, ensuring a tight seal to prevent hydraulic fluid from escaping. The dimensions of the oil seal, including its inner and outer diameters and thickness, are engineered to meet the exact specifications of the EX200-1 excavator's swing device.

Seal Type: The oil seal is likely to be of a lip seal type, featuring a flexible lip that makes contact with the rotating shaft of the swing device's hydraulic motor. This lip creates a dynamic seal that prevents fluid leakage while allowing the shaft to rotate smoothly.

Installation: Proper installation of the oil seal is critical to its effectiveness.

It should be installed by qualified technicians following manufacturer-recommended procedures, including using appropriate tools and lubricants.

Performance: The oil seal must maintain its sealing properties over an extended period of heavy-duty use. It should withstand the rigors of excavation work, including constant movement, vibration, and exposure to hydraulic pressures.

Maintenance: Regular inspection and maintenance of the swing device oil seal are essential to detect signs of wear, damage, or leakage. Timely replacement of the oil seal is necessary to prevent costly repairs and ensure the excavator's reliability.
