Product Description

DHCS Short Type Aluminum Oldham Flexible Shaft Coupling (Clamp Style)

Compact Sliding Disc Coupling with High-Strength Aluminum Hubs & PA66 Nylon Spacer

The DHCS Short-Type Clamp Style Oldham Coupling is a high-precision, space-saving flexible coupling designed for motion control systems requiring high torsional stiffness and electrical insulation. Constructed with high-strength aluminum alloy hubs and a high-durability imported PA66 nylon center spacer block, the DHCS series utilizes a sliding disc design to compensate for significant radial and angular misalignments while maintaining high sensitivity and low rotational inertia. Featuring a split detachable structure and clamp screw fastening, it is an ideal coupling solution for stepper motors, servo drives, and precision automation equipment.

Key Advantages & Features

Compact & Short-Type Design: Shortened overall length body structure provides a lightweight, highly responsive connection for tight axial spaces.
High-Strength Aluminum Alloy Hubs: Machined from high-grade aluminum alloy with an anodized surface treatment for high strength, wear resistance, and reduced system inertia.
Imported PA66 Nylon Center Spacer: Features an electric-insulating, oil-resistant, and corrosion-resistant PA66 slider block that effectively absorbs operational vibration and insulates drive shafts.
Large Radial Misalignment Compensation: The Oldham sliding-disc principle allows smooth compensation for high radial and angular shaft offsets without generating excessive bearing loads.
Detachable Clamp Screw Mounting: Clamping hub configuration enables tool-free quick installation, non-destructive shaft clamping, and easy replacement of the central pad.
High Torsional Rigidity & Sensitivity: High torque capacity with zero backlash characteristics, providing precise angular positioning for motor drives.
