SS Models

Product catalog summary

Overview: The document provides detailed specifications and ordering information for SS Models, which are high-pressure hydraulic actuators designed for various industrial applications such as lifting, turning, and clamping. These models operate at a maximum pressure of 3,000 PSI and offer up to 741,000 in/lbs of torque.

Specifications: The SS Models are available in 10 standard sizes, ranging from SS-.2A to SS-130. They are capable of single vane 280° rotation and double vane 100° rotation, with torque outputs varying by model and pressure. The document includes detailed dimensional data and performance metrics for each model, such as torque, volumetric displacement, and weight.

Mounting and Configuration: The actuators can be mounted in various configurations including base, end, and foot mounting. Specific models like the SS-25-2V require mounting at both ends to prevent torsional racking. Shaft configurations and modifications are customizable, with options for different seal materials and porting types.

Performance and Testing: Performance data is provided for both single and double vane models at pressures of 1,000, 2,000, and 3,000 PSI. The document outlines maximum allowable by-pass leakage and test parameters for oil, emphasizing the importance of consulting the factory for applications exceeding 2,000 PSI.

Ordering Information: A detailed guide on how to order is included, specifying the need to fill in blocks for style, size, number of vanes, mounting, seals, shaft configuration, shaft modification, and porting. Each block has specific options denoted by letters and numbers, allowing for precise customization of the actuator.
