Product Description

Excavator bottom rolleris a component of excavator or bulldozer that is located at the bottom of the machine and supports the weight of the track. Excavator bottom roller have double-row, sealed, and lubricated design that protects the shaft and bearing from debris and dust.

The tracks on excavators or bulldozers are made up of a series of interlocking metal plates, and the excavator bottom roller sit along the length of the track and support it as the machine moves. The basic structure of a Excavator bottom rollerconsists of an outer ring, an inner ring, a roller bearing, and a shaft. The outer ring is made of high-quality steel, and the surface is heat-treated for improved toughness and wear resistance. The inner ring is typically made of low-carbon alloy steel and heat-treated to wear-resistant properties. The roller bearing is designed to be sealed to ensure that foreign bodies will not enter, and multiple sealing components are added to ensure safe and long-term functionality.

Excavator bottom roller are critical components that support the weight of the excavator or bulldozer, reduce vibration, and improve the stability of the machine. excavator bottom roller directly affect the running speed, fuel consumption, and efficiency of the machine. As such, excavator bottom roller must be made of high-quality materials and designed for rugged application.

The following are some of the common characteristics and features of excavator bottom roller:High wear resistance: excavator bottom roller are exposed to harsh environments and need to withstand the wear and tear caused by heavy loads, uneven terrain, and debris. These components are typically made of high-quality steel and undergo heat treatment to improve their durability and wear resistance.

Effective sealing: excavator bottom roller are designed to be sealed tightly to prevent dust, dirt, and debris from entering into the bearing. Seals are placed on each end of the roller to eliminate any gaps.

Lubrication: excavator bottom roller require regular lubrication to ensure the smooth movement of the machine. Lubrication holes are usually added to the rollers to make the lubrication process easier.

Low noise: The bearings of the excavator bottom roller have a special design that helps to reduce noise during operation.

Easy installation: excavator bottom roller have a simple structure and are easy to install and maintain. They can be removed and replaced without dismantling the entire track assembly.Compatibility: excavator bottom roller are designed to fit specific models of excavators or bulldozers. These components should be chosen carefully to ensure compatibility with the machine.
