SW 95 Jaw Flex Coupling: High-Performance Power Transmission The SW 95 Jaw Flex Coupling is a robust, general-purpose industrial coupling designed to connect two shafts while efficiently transmitting torque and damping system vibrations. Part of the radially removable elastomer series, the SW 95 is uniquely engineered for ease of maintenance, allowing for quick inspection or replacement of the flexible element without needing to dismantle the connected machinery.
Based on standardized technical data, the SW 95 model offers a compact footprint with high power density:
Torque Capacity: * Synthetic Rubber: 21.10 Nm.
Polyurethane: 31.7 Nm.
H-Trans: 52.8 Nm.
Power Rating: 0.22 kW at 100 rpm (Synthetic Rubber).
Maximum Bore Diameter: 28 mm.
Dimensions: * Outside Diameter ($\varnothing$A): 65 mm.
Overall Length (TL1): 63 mm.
Gap (G): 2 mm.
Material: High-grade Cast Iron (Grade FG 260) hubs for maximum durability.
Approximate Weight: 0.80 kg.
The SW 95 coupling consists of two metallic hubs and a central flexible "spider" or "snap wrap" element.
Compression Loading: Torque is transmitted as the jaws of the driving hub push against the lobes of the elastomeric spider, which is then compressed against the jaws of the driven hub.
Radial Removal: The "SW" design features a snap-around element. Unlike standard couplings where you must slide hubs apart to change the insert, the SW 95 allows you to simply remove the retaining ring and replace the element radially.
Misalignment Handling: The flexible spider deforms slightly to absorb angular (up to 1°), parallel, and axial misalignments, protecting connected bearings and motors from premature wear.
Reduced Downtime: The radially removable "Snap Wrap" element allows for 5-minute replacements without disturbing the shaft alignment.
Fail-Safe Operation: Should the elastomeric spider wear out, the metallic jaws will intermesh and continue to transmit torque, preventing sudden system failure until maintenance can be performed.
No Lubrication Required: The coupling operates dry, making it ideal for environments where grease or oil could contaminate products.
Vibration Damping: Absorbs shock loads and dampens torsional vibrations, leading to quieter operation and longer equipment life.
Resistance to Harsh Environments: Built to withstand oil, dirt, sand, and moisture.
The SW 95 is a versatile solution used across multiple industries for light to medium-duty applications:
Pumps & Compressors: Ideal for centrifugal pumps where vibration control is essential.
Conveyors: Used in material handling systems for smooth start-stop operations.
Blowers & Fans: Provides reliable power transmission in HVAC and ventilation systems.
Manufacturing Equipment: Common in mixers, agitators, and general industrial rotating machinery.
Robotics: Suitable for applications requiring precise alignment and compact design.
The SW 95 Jaw Flex Coupling is the industry standard for operators who prioritize maintenance efficiency and equipment longevity. By combining a high-torque cast iron build with the convenience of a radially removable snap-wrap element, it minimizes operational costs while providing a fail-safe connection for critical industrial systems.
