Piston Guide 3201195004 – Atlas Copco Rock Drill Spare Part

Product Description

The 3201195004 piston guide is a specialized precision alignment and wear-resistant protective component for Atlas Copco Epiroc rock drills, crucial for maintaining the drill's efficient impact performance. Installed between the reciprocating piston and the main housing, it stabilizes the piston during high-speed reciprocating motion, eliminating lateral contact between the piston and housing and preventing premature wear. It creates a smooth, wear-resistant interface between the piston and housing, reducing energy loss and extending the service life of these two core components.

Technical Specifications

Core Advantages

1. Alignment Accuracy: The guide’s multi-step inner bore (visible in product images) fits the Epiroc piston with minimal clearance (0.02–0.03mm), ensuring the piston stays centered during every impact cycle.
2. Sealing Grooves: The integrated circumferential grooves (seen in photos) retain hydraulic fluid to form a self-lubricating film, further reducing friction and heat buildup.
3. Corrosion Resistance: Manganese brass’s natural resistance to mine moisture, dust, and hydraulic fluid residues eliminates rusting or scaling—maintaining performance in harsh operational environments.
4. Mounting Design: The guide’s outer profile and flange (visible in images) align 1:1 with Atlas Copco Epiroc rock drill housings—no modifications, shims, or adapters are needed for installation.

Application Scenarios

The 3201195004 Piston Guide is essential for:

• Atlas Copco Epiroc rock drills (e.g., T35, T45) drilling hard-rock blasting holes (mining operations, up to 35m depth).
• Epiroc units performing tunnel anchor/support hole drilling (infrastructure projects, dense granite/basalt formations).
• Epiroc drill maintenance/overhaul (replacing worn, deformed, or misaligned original piston guides).
