Features:
Higher carrying capacity
This John Deere 27D roller is made from high-quality carbon steel and is forged for strength and durability. It is able to withstand various terrain challenges and heavy loads while maintaining optimal performance in demanding operating environments. As a result, the roller has a long service life, typically 1,000 to 3,000 operating hours.
Improve wear resistance
The top rollers of the excavator are designed with forged steel and are highly wear-resistant to ensure optimal load-bearing capacity. Given that excavators are often used on rough terrain, the rollers are in constant contact with ground debris and the rubber track system, so they are prone to wear over time. That's why it's crucial to use heavy-duty replacement parts specifically for your John Deere 27D.
Prevent contaminants from penetrating
Our rollers are sealed to protect against environmental contaminants such as dust, debris, and moisture, mitigating potential damage. The design of these rollers focuses on maintaining optimal oil retention to promote smooth operation and long service life.
