SW 100 Jaw Flex Coupling: High Torque with Maximum Bore Versatility The SW 100 is an industrial-grade jaw coupling designed for heavy-duty power transmission in demanding environments. It belongs to the Snap Wrap (SW) category, meaning it features a radially removable elastomeric element. This design is engineered specifically to eliminate the need for moving the motor or driving machine during maintenance, drastically reducing operational downtime.
The SW 100 maintains high performance while offering increased mechanical flexibility:
Torque Capacity:
Synthetic Rubber: 46.40 Nm.
Polyurethane: 69.6 Nm.
H-Trans: 116 Nm.
Power Rating: 0.49 kW at 100 rpm (Synthetic Rubber).
Maximum Bore Diameter: 35 mm (5 mm larger than the SW 99).
Dimensions:
Outside Diameter ($\varnothing$A): 78 mm.
Overall Length (TL1): 88 mm.
Gap (G): 2 mm.
DBSE (Distance Between Shaft Ends): 140 mm.
Hub Material: Premium Grade FG 260 Cast Iron for superior strength and vibration damping.
The SW 100 functions as a flexible bridge between two shafts:
Direct Drive: The two hubs lock together via an elastomeric spider, ensuring 100% torque transmission.
Extended Reach: With an overall length of 88 mm and a DBSE of 140 mm, it is ideal for systems where the motor and the driven equipment are spaced further apart.
Radial Element Access: To replace a worn insert, you simply slide back the retaining ring and pull the "Snap Wrap" spider out through the side. There is no need to loosen or realign the hubs.
Superior Bore Capacity: Accommodates larger shafts (up to 35 mm) compared to other models in its torque class.
Eliminates Realignment: Because the hubs stay fixed on the shafts during element changes, you never lose your precision alignment.
Shock & Vibration Control: The flexible spider acts as a cushion, absorbing shock loads and reducing noise across the drive train.
Fail-Safe Security: If the elastomer fails due to extreme wear, the metal jaws remain interlocked to prevent a total loss of power.
Cost-Effective: No lubrication or specialized maintenance tools are ever required.
The SW 100 is the preferred choice for applications where larger shaft sizes meet high torque requirements:
Large Water Pumps: Reliable for continuous duty in irrigation or industrial cooling.
Heavy Conveyors: Handles high start-up torque in mining or warehouse logistics.
Crushers and Mixers: Damps the heavy vibrations typical in material processing.
Industrial Fans: Ideal for HVAC systems requiring large bore connections to fans.
The SW 100 provides the perfect balance of power and adaptability. By matching the 116 Nm peak torque of the SW 99 but offering a larger 35 mm bore and longer reach, it serves as a versatile solution for specialized industrial machinery that requires both strength and ease of service.
