China HITACHI EX60-5 SWING DEVICE SLEW BOX BOTTOM BEARING 140 X 65 X 37 MM (OEM HI 4397242) | Tonkee®

Material Composition: The bearing is typically manufactured from high-quality materials, often featuring steel alloys, to provide durability and resistance to wear and tear.

This is essential in construction equipment, where components are subjected to heavy loads and harsh conditions.

Size and Dimensions: The dimensions of 140 x 65 x 37 mm indicate the bearing's outer diameter, inner diameter, and width, respectively. These measurements ensure that the bearing fits precisely within the excavator's swing mechanism, maintaining stability and efficiency during operation.

Load-Bearing Capacity: The bearing is designed to withstand significant loads, as it is a critical component in supporting the weight of the upper structure of the excavator during rotation. This high load-bearing capacity ensures safe and efficient operation.

Precision and Tolerance: Bearings are engineered with tight tolerances to minimize play or slack in the rotating components. This precision ensures smooth and controlled movement of the excavator's upper structure, improving operator control and reducing wear and tear.

Sealing and Lubrication: Proper sealing and lubrication are essential to prevent contaminants such as dirt, dust, and moisture from entering the bearing, which can lead to premature wear and failure.

Maintaining a well-lubricated bearing is crucial for its longevity and performance.

Compatibility: The bearing is specifically designed as an OEM part for the Hitachi EX60-5 excavator model, ensuring perfect compatibility and fit. It's important to use genuine OEM parts to maintain the excavator's performance and warranty.

Maintenance and Replacement: Like all mechanical components, the swing device slew box bottom bearing will eventually require maintenance or replacement due to wear and tear. Regular inspections and maintenance routines can help prolong the lifespan of this critical component.
