Low Inertia Clutch

Product catalog summary

Overview: WPT Low Inertia (LI) Clutches are designed for high cycle applications such as steel shears and stamping presses. The low inertia design reduces rotational mass during starts and stops, increasing cycles per minute and reducing deceleration times, which also minimizes heat generation during dynamic braking.

Specifications: The clutches are available in 1, 2, or 3 plate constructions with diameters ranging from 6 to 60 inches. They feature high cycle life, predictable preventative maintenance, and optional hydraulic actuation. Various center plate designs are available, including slotted, solid, and ventilated.

Performance Data: The document provides detailed specifications for different models, including torque ratings, maximum speed, weight, inertia, and lining area. For example, Model 106 has a torque rating of 4520 lbf∙in (510 N∙m) at 100 psi, with a maximum speed of 3930 r/min and a weight of 23 lb (10 kg).

Mounting Dimensions: The document includes detailed mounting dimensions for both imperial and metric systems, specifying hole circle diameters, quantities, and other critical measurements for each model.

Recommendations: It is advised to consult WPT Application Engineering for application assistance, service factors, specifications, and detailed drawings or 3D models. Dynamic (slipping) torque is noted to be 75% of the static torque.
