SW 110 Jaw Flex Coupling: High-Torque Industrial Strength The SW 110 is a heavy-duty power transmission solution designed for high-torque applications where system reliability is critical. As part of the Snap Wrap (SW) series, it utilizes a radially removable elastomeric element that allows for "in-place" maintenance. This design enables operators to replace the flexible insert without moving the motor or the driven machine, significantly reducing labor costs and downtime.
The SW 110 is built for high-performance machinery requiring robust shaft connections:
Torque Capacity:
Synthetic Rubber: 89 Nm.
Polyurethane: 133.5 Nm.
H-Trans: 222.5 Nm.
Power Rating: 0.93 kW at 100 rpm (Synthetic Rubber).
Maximum Bore Diameter: 42 mm.
Dimensions:
Outside Diameter ($\varnothing$A): 96 mm.
Overall Length (TL1): 108 mm.
Length thru' Bore (L1): 43 mm.
Gap (G): 3 mm.
Hub Material: High-strength Cast Iron (Grade FG 260).
The SW 110 acts as a flexible link between a drive motor and driven equipment:
Compression Transmission: Torque is transferred through the compression of the elastomeric spider lobes between the interlocking jaws of the two hubs.
Misalignment Compensation: The flexible spider absorbs angular, parallel, and axial misalignments, preventing stress on bearings and seals.
Radial Element Access: Maintenance is simplified by removing a retaining ring; the "Snap Wrap" spider can then be replaced from the side without dismantling the drive train.
Superior Torque Performance: Capable of handling up to 222.5 Nm of torque, making it suitable for larger industrial motors.
Maintenance Efficiency: The radial-entry design eliminates the need for shaft realignment after spider replacement.
Fail-Safe Operation: The jaw-on-jaw design ensures that power transmission continues even if the elastomeric element fails under extreme conditions.
No Lubrication Needed: Operates cleanly without oil or grease, reducing environmental contamination and maintenance needs.
Vibration Damping: Effectively dampens torsional vibrations and shock loads, extending the life of connected components.
The SW 110 is commonly found in heavy-duty industrial environments:
Large-Scale Pumps: Ideal for high-pressure industrial pumping systems.
Processing Machinery: Used in industrial mixers, agitators, and shredders.
Heavy Conveyors: Suitable for heavy-duty material handling in mining or construction.
Gearbox Connections: Provides a reliable link between electric motors and large gear reducers.
The SW 110 is the preferred choice for industrial applications that demand a combination of high torque (up to 222.5 Nm) and ease of maintenance. Its 42 mm bore capacity and radially removable design make it an exceptionally versatile and cost-effective component for keeping heavy production lines operational with minimal downtime.
