51779049 Ingersoll Rand OEM Coupler

This 51779049 Ingersoll Rand OEM Coupler is a heavy-duty, flexible component critical for protecting the drive train of rotary screw air compressors and other industrial equipment. The part number 51779049 specifically identifies this coupler as a genuine Original Equipment Manufacturer part. Generally, this type of coupling is a high-speed, elastomeric component designed to manage the significant rotational forces and minor misalignments inherent between a motor and a compressor air-end. Therefore, it acts as a critical shear element, protecting expensive machinery from damage during sudden shock loads or component failure.

Product Quality and Function

Stark Industrial Products provides only high-quality drive couplings. We guarantee all of our drive couplers are Original Equipment Manufacturers’ (OEM) equipment. Consequently, we offer nothing but OEM unless we are matching up a discontinued item.

• This coupler ensures reliable, backlash-free rotational force transmission from the prime mover to the driven component.
• It features a design that effectively compensates for the small parallel, angular, and axial misalignments that occur during machine operation.
• Furthermore, the elastomeric element absorbs and dampens torsional vibrations, thereby reducing stress on shafts and bearings.
• Because the coupler acts as a deliberate weak point in the system, it protects the motor and air-end; specifically, the element fails first in the event of a catastrophic jam or overload.
• Maintenance staff can often install or replace the element with minimal disruption to the overall system.

Industry Applications and Brands

Our couplers see wide use in drives for equipment across various demanding sectors.

• This component is primarily used in the drive systems of Ingersoll Rand portable and stationary rotary screw air compressors.
• The part is specified for use across several compressor models, including those used in construction, mining, drilling, and general industrial applications.
• Typical applications also include heavy equipment such as crawler rotary drilling rigs, where it connects the engine to the hydraulic pump or air-end.
• Some of the leading equipment and heavy machinery brands we supply drive couplings for include Ingersoll Rand, Atlas Copco, Doosan, and other major manufacturers of compressed air and heavy construction equipment.
