China HITACHI EX60-2-3 SWING DEVICE SLEW BOX MOTOR OIL SEAL 55 X 36 X 12 (OEM HI 0433905) | Tonkee®

The oil seal, with its dimensions of 55 x 36 x 12 mm, is designed to fit precisely within the swing device of the Hitachi EX60-2 and EX60-3 excavators.

These dimensions are crucial, as they determine the seal's compatibility with the device, ensuring a tight and effective seal to prevent oil leakage.

The primary function of this oil seal is to create a barrier between the internal components of the swing device and the external environment. This seal is essential because the swing device contains oil to lubricate its moving parts and reduce friction. Without a proper seal, this oil could leak out, leading to decreased performance, increased wear and tear, and potential damage to the excavator's swing device components.

The material used for manufacturing this oil seal is typically a high-quality synthetic rubber or elastomer. These materials are chosen for their ability to withstand the harsh operating conditions of an excavator, including exposure to hydraulic fluids, temperature variations, and mechanical stress. The specific material used may vary based on the manufacturer and the quality standards they adhere to.

The 55 x 36 x 12 mm oil seal is precision-engineered to meet OEM (Original Equipment Manufacturer) specifications, which means it meets the exact design and performance requirements set by Hitachi for their excavators.

This ensures that the oil seal will perform reliably and effectively in the demanding conditions these machines often encounter.

Installation of the oil seal requires careful attention to detail. It must be properly seated and sealed to prevent any gaps that could lead to oil leakage. Additionally, the installation process may involve cleaning and inspecting other components of the swing device to ensure they are in good condition, as a damaged or worn component could compromise the effectiveness of the oil seal.

Regular maintenance and inspection of the swing device and its components, including the oil seal, are essential to prolong the life of the excavator and ensure it operates at peak efficiency. This includes checking for signs of wear or damage to the oil seal, such as cracks, tears, or deformation, and replacing it if necessary.
