The SW 350 is the largest and most robust model in the "Snap Wrap" series shown in the technical specifications. Built for extreme industrial environments, it is designed to transmit massive amounts of torque while maintaining the signature flexibility and serviceability of the jaw-coupling design. As the top-tier model in this range, the SW 350 is the preferred choice for high-horsepower applications where equipment downtime must be kept to an absolute minimum.
The SW 350 sets the standard for heavy-scale power transmission with the following performance data:
| Specification | Metric Value |
| Rated Torque (Synthetic Rubber) | 4308 Nm |
| Rated Torque (Polyurethane) | 6462 Nm |
| Power Rating @ 100 RPM | 45.1 kW (Rubber) / 67.7 kW (PU) |
| Maximum Bore Capacity (D) | 115 mm |
| Overall Length (TL1) | 309 mm |
| Outside Diameter (ØA) | 323 mm |
| Gap (G) | 3 mm |
The SW 350 utilizes a high-strength jaw-and-spider mechanism designed for radial accessibility:
Compression Drive: Power is transferred through an elastomeric element (the spider) that is placed in compression between the interlocking jaws of the two hubs.
Radial Element Removal: The "SW" (Snap Wrap) designation means the elastomer is a wrap-around component. By removing a steel retaining ring, the element can be replaced radially.
Shaft Alignment: Despite its size, the SW 350 is highly effective at accommodating parallel and angular shaft misalignments, protecting the internal components of the motor and the driven machine.
Unmatched Torque Capacity: With a rating of up to 6462 Nm, this coupling can handle the most demanding industrial loads.
Maintenance Without Displacement: The greatest advantage is the ability to change the flexible element without moving the motor or the driven equipment, saving hours of labor and re-alignment time.
High Bore Versatility: Accommodates large-diameter shafts up to 115 mm, making it compatible with high-frame-size industrial motors.
Fail-Safe Reliability: The rugged cast-iron jaws provide a mechanical backup; if the elastomer fails, the jaws will lock to prevent a total disconnect of the drive system.
Vibration Isolation: Effectively isolates the motor from the shocks and vibrations of heavy-duty industrial processes, extending the life of bearings and seals.
The SW 350 is engineered for the "big iron" of the industrial world:
Large Industrial Mixers: Handling high-viscosity materials in chemical and food processing.
Heavy-Duty Crushers & Shredders: Managing the extreme shock loads found in recycling and mining operations.
Primary Pump Stations: Reliable operation for municipal water and wastewater transport.
Marine Propulsion: Connecting auxiliary engines and large-scale power take-offs.
The SW 350 is the ultimate solution for heavy-duty power transmission within the Snap Wrap family. It offers the highest Power Rating (67.7 kW @ 100 RPM) and the largest Outside Diameter (323 mm) of the series. By choosing the SW 350, operators ensure their high-torque systems are protected by a coupling that is as easy to maintain as it is powerful.
