CAM ROLLER

In Stock

The CAM ROLLER 3719 0115 09 is a key component within the rock drill's percussion mechanism. It plays a direct role in timing the impact cycle, which is essential for maintaining the drifter's power and overall drilling efficiency. Using the correct roller prevents premature wear on internal parts.

Full Technical Description

CAM ROLLER 3719 0115 09 Operating deep inside the drifter, the cam roller follows a cam profile to actuate the main valve. This movement precisely directs high-pressure hydraulic oil to drive the impact piston back and forth. Its function is fundamental to converting hydraulic flow and pressure into the consistent, high-frequency percussion needed to break rock effectively.

A worn or failing cam roller directly impacts drilling performance. The precise timing of the impact cycle is lost, resulting in a noticeable drop in impact energy and a slower penetration rate. In a worst-case scenario, a seized roller can cause catastrophic damage to the drifter's internal components, leading to extended downtime and expensive repairs.

Weak or erratic percussion is a common symptom of a worn cam roller. Since this is an internal component, it is typically inspected and replaced during a scheduled drifter overhaul. When the drifter is disassembled, check the roller for any flat spots or resistance to turning and replace it to ensure reliable operation.
