Ingersoll Rand Drill Hammer Piston Size 140

The Ingersoll Rand Drill Hammer Piston is a key component in the pneumatic or hydraulic drill hammers of this company. This piston is essentially the heart of the hammer, repeatedly striking the bit to provide the necessary energy to break rocks or mineral materials.

Common technical specifications of the Ingersoll Rand drill hammer piston (depending on the model):

Note: There are various models such as IR T4W, IR YH65, IR DTH Hammer QL Series, etc., and the exact specifications vary depending on the model.

General Features of the Drill Hammer Piston:

1. Material:

   • Alloy of chromium-molybdenum steel (Cr-Mo Steel)

   • Heat-treated for wear and fatigue resistance

   • Typical hardness between 52–58 HRC

2. Function:

   • Reciprocating motion at high frequency

   • Direct impact transmission to the bit shank

   • High-precision design to generate appropriate air pressure in each impact cycle

3. Mechanical Specifications (Sample):

   • Diameter: From 60 to 180 millimeters (depending on the hammer model)

   • Length: 300 to 900 millimeters

   • Weight: 5 to 60 kilograms

4. Design considerations:

   • Internal air channel design for compressed air distribution
