Carrier rollers and track rollers are both important components of a crawler excavator, bulldozer, or any tracked machinery. While they may look similar, they have different functions and operate differently.
What is Carrier Roller
A carrier roller, also known as a top roller or upper roller, is a component of the undercarriage of tracked machinery such as excavators, bulldozers, and other construction equipment. The carrier roller is located at the top of the undercarriage and serves to support the weight of the track chain and distribute the weight evenly across the undercarriage. The carrier roller typically has a cylindrical shape with a bearing in the center and rotates on an axle, allowing the track chain to move smoothly and reduce friction. Carrier rollers play an important role in ensuring the stability and durability of the undercarriage and preventing premature wear and tear of the track chain.
Carrier rollers are designed to support the weight of the track chain and distribute the weight evenly across the undercarriage. They are typically located at the top of the undercarriage and serve to keep the track chain in place. Carrier rollers are also known as top rollers or upper rollers.

what is Track rollers
Track rollers, also known as bottom rollers or lower rollers, are components of the undercarriage of tracked machinery such as excavators, bulldozers, and other construction equipment. The track roller is located at the bottom of the undercarriage and serves to support the weight of the machine on the ground and guide the track chain around the sprocket and idler wheels. The track roller typically has a cylindrical shape with a bearing in the center and rotates on an axle, allowing the track chain to move smoothly and reduce friction. Track rollers play an important role in ensuring the stability and traction of the machine on the ground and absorbing shock and impact from rough terrain, as well as preventing premature wear and tear of the track chain.
Track rollers, on the other hand, are located at the bottom of the undercarriage and support the weight of the machine on the ground. They guide the track chain around the sprocket and idler wheels, which help propel the machine forward. Track rollers are also known as bottom rollers or lower rollers.
要約すれば, the primary difference between carrier rollers and track rollers is their location and function within the undercarriage. Carrier rollers support the track chain and distribute its weight evenly, while track rollers support the weight of the machine on the ground and guide the track chain.
