Coupling assembly MPP®

Description
Compact flange-mounted flexible coupling designed for reduced torque transmission. Features a polyurethane Maltese-cross flexible element and cast-iron flanges with drive segments supplied unbored (except 633054 and 633055). The MPP® design provides interlocking mounting and a smooth cylindrical external profile.

Benefits

• Reduced overall size for constrained installations
• Simple assembly by interlocking and flange mounting
• Elastic element works in compression for predictable torque transmission
• Positive locking for safe torque transfer
• Wide operating temperature range: -30°C to +70°C (continuous)
