Both carrier roller and track roller are an important part of a tracked excavator, bulldozer or other track tracked machine. Although they look similar, their functions and operations are different.
1. What is a carrier roller
The carrier roller also known as the top roller or upper roller, is a component of the undercarriage of tracked machines such as excavators, bulldozers and other construction equipment. Located at the top of the undercarriage, the sprocket supports the weight of the track chain and distributes the weight evenly across the undercarriage. Usually cylindrical in shape with a bearing in the center, the sprocket rotates around a shaft and is responsible for the smooth movement of the track chain and reduces friction. The sprocket plays an important role in ensuring the stability and durability of the undercarriage and preventing premature wear of the track chain.
Carrier roller are used to support the weight of the track chain and distribute the weight evenly across the chassis. They are usually located on top of the undercarriage and are used to hold the track chain in place.
2. What is a track roller
Track roller also known as bottom rollers or lower rollers, are components of the the under carriage of tracked machinery such as excavators, bulldozers and other construction equipment. Located at the bottom of the undercarriage, the rollers are used to support the weight of the machine on the ground and guide the track chain around the sprockets and idlers. Rollers are usually cylindrical in shape with bearings in the center and rotate around a shaft to move the track chain around the sprockets and idlers. Rollers are usually cylindrical in shape with bearings in the center and rotate around a shaft to move the track chain smoothly and reduce friction. Rollers play an important role in ensuring stability and traction of the machine on the ground, as well as absorbing shocks from rough terrain and preventing premature wear of track chain.
On the other hand, the rollers are located at the bottom of the chassis and support the weight of the machine on the ground. They guide the track chain around the sprockets and idler pulleys, thus propelling the machine forward, and the rollers are also known as bottom rollers or lower rollers.
In summary, the main difference between a track roller and a track support roller is their position and function within the chassis. The carrier roller support the track chain and distributes the weight evenly, while the track roller supports the weight of the machine on the ground and guides the track chain.
