Description
Overview:
The Coupling Spider fits Atlas Copco LP 9-20 Power Pack (MPN 3377 0051 69) is a genuine Atlas Copco flexible coupling insert for hydraulic power packs. Moulded from tough polyurethane elastomer in a high-visibility yellow, it sits between the metal coupling hubs to transmit drive while cushioning torsional shock and vibration. This protects pumps, motors and engines from excessive wear and helps maintain smooth running. Designed for harsh site use, the material is resistant to oil and abrasion and remains stable across typical operating temperatures. It is sized to suit Atlas Copco assemblies for an accurate fit and reliable performance. Ideal for routine servicing or as a direct replacement, it suits popular models including LP9-20E and LP13-30 EU.
Key Features:
- Genuine Atlas Copco OEM coupling insert (MPN 3377 0051 69) for assured fit and performance
- Durable polyurethane elastomer construction resists oil, fuel splash and abrasion
- Cushions vibration and shock loads to reduce wear on shafts, seals and bearings
- Maintains torque transmission while accommodating minor misalignment in the drive
- Direct replacement for a worn or cracked spider to restore coupling performance
- Simple, tool-light installation for quick turnaround and minimal downtime
- Stable in demanding site conditions and continuous-duty applications
- Suitable for professional fleets, plant hire, utilities and maintenance teams
Typical Applications:
Used in Atlas Copco hydraulic power packs driving breakers, pumps and other hydraulic tools. Commonly fitted during planned maintenance to prevent driveline damage, or as a corrective replacement when the existing spider shows cracking, hardening or deformation. Suitable for construction, demolition, roadworks, utilities, rail and plant hire environments where reliable, low-vibration power transmission is required.
