Product Description

H Type Flexible Jaw Pin Coupling (N-EUPEX & N-EUPEX DS Equivalent)

Heavy-Duty Steel Shaft Coupling | Direct Interchange for Flender N-EUPEX Series

The H Type Flexible Pin & Jaw Coupling is designed for demanding power transmission applications requiring high torsional damping and rugged durability. Manufactured with high-strength forged steel hubs and elastomeric flexible inserts, this series serves as a direct, high-quality replacement for industry-standard Flender N-EUPEX and N-EUPEX DS series couplings. Available in standard sizes including H80, H95, H110, H125, H140, H160, and H180, it provides reliable shaft connection and misalignment compensation for heavy industrial machinery.

Key Advantages & Features

Direct Global Brand Interchange: Dimensional compatibility for quick and seamless replacement of Flender N-EUPEX and N-EUPEX DS series couplings, saving costly machinery downtime.
High-Strength Steel Construction: Premium forged/machined steel hubs deliver exceptional impact resistance, fatigue strength, and high rated torque capacity up to 500 N·m (and higher for larger frame sizes).
Torsional Vibration Damping: High-performance elastomeric elements absorb operational shock loads, reduce noise, and damp harmful torsional vibrations across drive systems.
Multi-Directional Misalignment Compensation: Effectively accommodates radial, axial, and angular shaft deviations to protect motor bearings, gearboxes, and driven machinery.
Fail-Safe & Durable Design: Engineered for continuous operation in severe industrial environments, ideal for machinery overhaul, OEM equipment, and repair shops.
