Hot sale HITACHI EX100 120-5 SWING DEVICE SLEW BOX PLATE THRUST SPACER 1 (OEM HI 4269480) | Tonkee®

The OEM part number for this component is HI 4269480, and it is manufactured to meet Hitachi's stringent quality and performance standards.

This spacer is a critical part of the excavator's swing mechanism, and its specifications are crucial for maintaining the excavator's optimal performance.

The swing device, also known as the slewing mechanism, is responsible for allowing the excavator's upper structure, including the boom, arm, and bucket, to rotate horizontally. This rotation is essential for precise positioning and digging in various directions. The slew box plate thrust spacer is a vital component within the swing device, as it helps to control and distribute the loads generated during the swinging operation.

The primary function of the thrust spacer is to provide support and maintain the proper spacing between the various components of the swing device, including the slew ring and the slew box plate. It ensures that there is minimal friction and wear between these components, thus prolonging their lifespan and reducing maintenance requirements.

The material used for manufacturing this spacer is carefully selected to withstand the significant forces and stresses it encounters during operation.

High-quality materials and precision machining are essential to ensure the spacer's durability and reliability.

Furthermore, the dimensions and tolerances of the spacer are engineered to perfection to ensure that it fits precisely within the excavator's swing device. This precise fit is critical for the smooth and precise rotation of the upper structure, as any misalignment or excessive play can result in reduced performance and potential damage to the components.

Proper lubrication and maintenance of the swing device, including the thrust spacer, are essential to ensure the excavator's longevity and reliable operation. Regular inspections and lubrication schedules must be followed to prevent premature wear and failure of these components.
