FAQ

Is this buffer piston an original Atlas Copco part or a certified aftermarket replacement?
This is a certified OEM-spec replacement manufactured to Atlas Copco’s dimensional, material, and performance specifications — traceable batch testing included.
Will it fit other Atlas models like RD20 or COP series?
No — it is engineered exclusively for the RD18U. Dimensional and functional differences make it incompatible with RD20, COP1800, or other models.
What is the typical lead time for bulk orders (50+ units)?
Standard lead time is 7–10 business days; expedited shipping available. Stock held for common quantities up to 200 units.
How does this piston improve maintenance intervals compared to generic alternatives?
Validated field data shows 2.3× longer service life vs. standard-grade replacements — reducing unscheduled downtime by ~18% per drill rig annually.

Detailed Description

Buffer Piston (Part No. 3201195404) – Suitable for Atlas RD18U Rock Drill

The Buffer Piston, part number 3201195404, is a critical damping component used in the Atlas RD18U rock drill. Its primary function is to absorb residual impact energy and reduce vibration transmission within the drill, ensuring smoother operation and protecting key components such as the shank adapter and front head assembly.

Description

Manufactured from high-strength alloy steel, the buffer piston is engineered to withstand extreme percussive forces and cyclic loads generated during rock drilling. Positioned at the rear or buffer section of the impact mechanism, it acts as a shock absorber that helps control piston rebound and minimizes mechanical stress on the drill housing.

The result is enhanced drill stability, reduced wear, and longer component life, making it essential for high-performance and reliable drilling in demanding applications.
