The SW 190 is a professional-grade power transmission component engineered for reliability and extreme durability. As part of the Snap Wrap (SW) series, it is specifically designed to allow for the radial removal of the flexible element. This means that the elastomeric spider can be replaced in minutes by simply removing a retaining ring, without the need to unbolt or move the motor and the driven machinery.
The SW 190 provides a massive leap in power handling compared to smaller models:
Torque Capacity: * Synthetic Rubber: 190 Nm.
Polyurethane: 285 Nm.
H-Trans: 475 Nm.
Power Rating: 2.0 kW at 100 rpm (using Synthetic Rubber).
Maximum Bore Diameter: 60 mm.
Dimensions: * Outside Diameter ($\varnothing$A): 129 mm.
Overall Length (TL1): 133 mm.
Length thru' Bore (L1): 54 mm.
Gap (G): 3 mm.
DBSE (Distance Between Shaft Ends): 140 mm.
Hub Material: Manufactured from high-tensile Cast Iron (Grade FG 260) for maximum strength.
The SW 190 functions as a fail-safe flexible link between two rotating shafts:
High-Load Transmission: Power is transferred through the compression of the elastomeric lobes between the heavy-duty cast iron jaws.
Shock Mitigation: The thick spider insert absorbs high-intensity shock loads and dampens torsional vibrations, protecting expensive motor windings and bearings.
Radial Maintenance: The "Snap Wrap" design allows the element to be replaced from the side. This is critical for the SW 190 because moving the large, heavy motors typically associated with this coupling size would be extremely labor-intensive.
Massive Torque Handling: Capable of transmitting up to 475 Nm of torque, making it suitable for large industrial drives.
Significant Labor Savings: The radial removal system eliminates the need for repeated shaft realignment, saving hours of maintenance time.
Fail-Safe Security: In the event of an elastomer failure, the metal jaws remain interlocked to prevent an immediate and dangerous loss of load.
Lubrication-Free: Operates perfectly in dry conditions, which is ideal for food, textile, or chemical processing where oil contamination is a risk.
Versatile Fitment: A 60 mm max bore allows this coupling to fit onto a wide range of large-diameter drive shafts.
The SW 190 is a staple in heavy industrial machinery:
Primary Drive Motors: Used as the main coupling for high-horsepower electric motors.
Large Centrifugal Pumps: Ideal for municipal water pumps and large-scale industrial fluid systems.
Heavy Duty Conveyors: Used in mining and bulk material handling where start-up loads are massive.
Industrial Mixers & Shredders: Handles the high-torque resistance required for processing dense materials.
The SW 190 is a powerhouse solution for industrial operators who require a combination of high torque capacity (up to 475 Nm) and a 60 mm bore diameter. By utilizing the "Snap Wrap" maintenance system, it ensures that even your largest machinery can be serviced quickly and easily, keeping your production lines moving with maximum efficiency.
