SW 150 Jaw Flex Coupling: Maximum Torque for Heavy Industry The SW 150 is a premium industrial coupling designed for high-stress power transmission environments. Utilizing the Snap Wrap (SW) radial removal system, it allows for the replacement of the internal elastomeric element without any need to move the motor or driving machine. This model is the go-to solution for large-scale operations where minimizing maintenance downtime is a top financial priority.
The SW 150 offers a massive increase in performance metrics:
Torque Capacity:
Synthetic Rubber: 141 Nm.
Polyurethane: 211.5 Nm.
H-Trans: 352.5 Nm.
Power Rating: 1.5 kW at 100 rpm (using Synthetic Rubber).
Maximum Bore Diameter: 48 mm.
Dimensions:
Outside Diameter ($\varnothing$A): 111 mm.
Overall Length (TL1): 115 mm.
Length thru' Bore (L1): 45 mm.
Gap (G): 3 mm.
Hub Material: High-grade Cast Iron (Grade FG 260) for maximum structural rigidity.
The SW 150 operates through high-load compression:
Interlocking Jaws: Two cast-iron hubs with heavy-duty jaws intermesh with a central elastomeric spider to transmit high levels of torque.
Energy Absorption: The flexible element deforms under load to absorb massive shock impacts and prevent torsional vibrations from traveling through the drive train.
Radial Maintenance: By simply sliding the retaining ring, the "Snap Wrap" spider can be removed and replaced radially (from the side). This eliminates the expensive labor of unbolting and realigning heavy machinery.
Massive Power Density: Capable of handling up to 352.5 Nm of torque in a relatively compact 111 mm diameter frame.
Unrivaled Serviceability: Allows for spider replacement in minutes, which is critical for 24/7 manufacturing plants.
Fail-Safe Reliability: The metal-on-metal jaw design ensures that if the elastomer is destroyed by an extreme overload, the system remains connected to prevent a catastrophic drop in load.
No Lubrication: Eliminates the risk of grease spray and the ongoing cost of lubricant maintenance.
Severe Duty Resistance: Specifically designed to function reliably in environments with high levels of dirt, oil, and moisture.
The SW 150 is designed for the most demanding equipment:
Large Industrial Pumps: High-capacity water treatment and sludge pumps.
Heavy Mixers & Agitators: Used in chemical and cement processing where high viscosity creates heavy loads.
Crushers & Mills: Excellent for primary material processing equipment that faces constant shock loads.
Main Drive Systems: Used as the primary coupling for large electric motors in factory production lines.
The SW 150 is the ultimate choice for heavy-duty industrial power transmission where both strength and maintenance speed are non-negotiable. With a 48 mm bore capacity and a peak torque of 352.5 Nm, it provides a secure, fail-safe connection that protects your most expensive machinery while ensuring downtime is kept to an absolute minimum.
