Bottom Roller

Production Description

The types of track rollers available for tracked excavators are diverse and numerous. These rollers serve a crucial purpose as they support the weight of the machine while it moves over the ground. There are various types of support rollers available, such as single-flange, double-flange, and triple-flange rollers. Each of these types performs a specific function, with some providing greater stability and others offering greater ease of movement. Single-flange rollers are typically used for light-duty applications, whereas double-flange and triple-flange rollers can handle heavier loads.
