No mundo das máquinas pesadas, As peças de material rodante desempenham um papel fundamental no desempenho e durabilidade. Entre essas partes, track rollers and roller carrier are essential for excavators and diggers. Understanding their functions and differences helps you choose the right components for your machines.
O que são rolos de esteira?
Rolos de esteira, also known as bottom rollers, support the weight of the excavator or digger. They are mounted along the bottom of the undercarriage and roll on the track chain to move the machine forward or backward.
Rolos de esteira:

- Maintain track tension and alignment
- Operate under heavy loads and harsh environments

|---|---|---|
| Localização | Bottom of the undercarriage | Top of the undercarriage |
| Função | Supports entire machine weight | Supports and guides the top of the track |
| Rolamento de carga | High load-bearing | Lower load-bearing |
| Wear Resistance | Extremely high due to ground contact | Lower as not in direct ground contact |
