As the “invisible guardian” of the upper undercarriage, this top roller is installed above the center of the undercarriage, with key roles:

Maintaining stable track tension for smoother equipment operation

�� Maintenance Reminder: Check Timely to Prevent Small Issues from Escalating

Whether rotation is smooth and free of abnormal noise
Whether the seal is intact and free of lubricant leakage
Replacing it promptly when problems are found is far more cost-effective than waiting until the fault worsens!
