Buy HITACHI EX100 120-1 SWING DEVICE SLEW BOX NEEDLE ROLLER BEARING (OEM HI 4184840) | Tonkee®

Dimensions and Specifications: The needle roller bearing HI 4184840 is designed to precise specifications to ensure optimal performance within the swing device.

Its dimensions, tolerances, and load-carrying capacities are engineered to meet the demanding requirements of the excavator's operation.

Material and Construction: Typically, needle roller bearings are constructed from high-quality alloy steel, which provides exceptional strength and durability. These bearings consist of cylindrical rollers that are much thinner in diameter than their length, allowing them to carry heavy radial loads. The design minimizes friction and heat generation, ensuring longevity even in high-stress applications like excavator swings.

OEM Component: The HI 4184840 needle roller bearing is an Original Equipment Manufacturer (OEM) component. This means that it is manufactured by the same company, Hitachi in this case, that produced the original equipment, ensuring compatibility and reliability. OEM parts are designed specifically for use in Hitachi EX100-1 and EX120-1 excavators, guaranteeing a perfect fit and performance.

Function: The primary function of the needle roller bearing within the swing device is to support the rotational movement of the excavator's superstructure, including the upper frame and the attached working equipment (e.g., arm, bucket). It allows for smooth and controlled rotation, enabling precise positioning of the excavator's digging or lifting equipment.

Load Capacity: Needle roller bearings are chosen for applications like excavator swing devices due to their ability to handle high radial loads.

This means they can withstand the substantial forces generated during the swinging motion of the excavator, ensuring stability and safety during operation.

Maintenance and Replacement: Over time, due to the high-stress environment and continuous use, components like needle roller bearings may wear out. Regular maintenance of the excavator involves inspecting these critical parts and replacing them when necessary. The availability of OEM components like the HI 4184840 needle roller bearing simplifies the replacement process, ensuring that the excavator continues to operate safely and efficiently.

Supplier Quality Assurance: Tonkee®, the supplier of this OEM part, is known for providing high-quality replacement components for construction equipment. This ensures that the needle roller bearing meets stringent quality standards and is built to withstand the challenging conditions of construction and excavation work.
