Product Description
Ruland JD32/51-98R Flexible Coupling Flector is a high-performance polyurethane jaw coupling component engineered to fit Ruland hubs with a 50.8 mm (2.000 inch) outer diameter. It forms part of a lightweight, low inertia three-piece jaw coupling assembly made of two aluminum hubs and an elastomeric spider insert, designed for zero-backlash torque transmission.
The polyurethane insert features a Shore A hardness rating of 98, ensuring maximum torque capacity with limited compliance while absorbing misalignment and reducing stress on connected shafts. The coupling can operate reliably at speeds up to 8,000 RPM, making it suitable for demanding industrial and mechanical power transmission applications.
The red-colored flector allows for quick visual identification and is engineered to accommodate angular misalignment up to 0.8°, axial misalignment up to 1.27 mm, and parallel misalignment up to 0.13 mm, maintaining efficient mechanical connection and minimizing wear.
Ideal for manufacturing, HVAC, automation, and laboratory equipment, this coupling spider provides vibration damping and precise torque transfer with a balanced design to reduce high-speed vibration. The component is metric hardware compatible and allows assembly flexibility with clamp or set screw hubs, supporting inch, metric, keyed, and keyless bores.
Durable polyurethane construction delivers strength and flexibility. Fits Ruland hubs with 50.8 mm OD (2 inch) for broad compatibility. 98 Shore A hardness ensures high torque capacity and limited compliance. Capable of compensating angular, axial, and parallel misalignments.
Supports operating speeds up to 8,000 RPM with balanced design. Three-piece jaw coupling design enhances customization and maintenance. Red color for straightforward identification during installation. Ideal for mechanical power transmission in industrial and laboratory settings.
Metric hardware for reliable assembly and installation. Explore the extensive range of power transmission couplings on EnvMart for compatible hubs, clamps, and accessories.
