SW 225 Jaw Flex Coupling: Industrial-Strength Power Transmission The SW 225 is a high-performance solution within the Snap Wrap (SW) series, engineered to handle extreme loads while offering unparalleled maintenance efficiency. It features a radially removable elastomeric element, which allows for rapid servicing without needing to move the motor or the driven equipment. This design is essential for heavy industrial setups where dismantling machinery for a simple spider replacement would lead to costly downtime.
The SW 225 offers a substantial increase in torque and bore capacity for large-scale operations:
Torque Capacity: * Synthetic Rubber: 265 Nm.
Polyurethane: 397.5 Nm.
H-Trans: 662.5 Nm.
Power Rating: 2.8 kW at 100 rpm (using Synthetic Rubber).
Maximum Bore Diameter: 65 mm.
Dimensions: * Outside Diameter ($\varnothing$A): 142 mm.
Overall Length (TL1): 153 mm.
Length thru' Bore (L1): 64 mm.
Gap (G): 3 mm.
DBSE (Distance Between Shaft Ends): 180 mm.
Hub Material: High-grade Cast Iron (Grade FG 260) for maximum durability and vibration damping.
The SW 225 functions as a fail-safe flexible link for high-load systems:
Load Distribution: Torque is transmitted through the compression of the elastomeric spider between the interlocking jaws of the cast-iron hubs.
Torsional Cushioning: The thick elastomeric insert acts as a shock absorber, protecting connected components from sudden torque spikes and resonant vibrations.
The SW Maintenance System: By sliding a metallic retaining ring, the "Snap Wrap" element can be replaced radially from the side. This preserves the alignment of the 65 mm shafts, ensuring a quick return to operation.
Exceptional Torque Capability: Handles up to 662.5 Nm of torque, making it suitable for high-horsepower industrial drives.
Minimized Downtime: The "in-place" element replacement system saves hours of labor compared to standard couplings.
Fail-Safe Reliability: The metallic jaws will continue to transmit power even if the elastomer fails, providing critical time for a controlled shutdown.
Zero Lubrication: Reduces fire hazards and contamination risks in industries like paper, textile, or chemical processing.
Durability: The cast-iron construction is resistant to moisture, oil, and atmospheric debris.
The SW 225 is built for the most demanding mechanical environments:
Heavy-Duty Centrifugal Pumps: Ideal for large-scale fluid handling in mining and chemical plants.
Industrial Agitators & Mixers: Handles the massive resistance found in material processing vats.
Conveyor Drive Systems: Used in heavy-duty material handling where high start-up torque is required.
Primary Power Transmission: Connecting high-capacity electric motors to industrial gearboxes.
The SW 225 is a powerhouse component for any industrial operation requiring high torque capacity (up to 662.5 Nm) and a large 65 mm bore. Its radially removable design ensures that your most critical machinery stays running with minimal maintenance interruption, combining the brute strength of cast iron with the smart convenience of the Snap Wrap system.
