0749341040 - ESAB 40 Es Circlip Retaining Ring

Genuine ESAB Replacement Component

The ESAB Spring Retaining Ring 40 Es (Part Number: 0749341040) is a specialized mechanical fastener designed for use in ESAB welding equipment. As an Original Equipment Manufacturer (OEM) component, this retaining ring meets the strict engineering standards set by ESAB, ensuring optimal performance and longevity within your industrial machinery. Retaining rings, also known as circlips or snap rings, play a pivotal role in mechanical assemblies by acting as a shoulder to hold components—such as bearings, gears, or pulleys—securely onto a shaft or within a bore.

Constructed from high-quality spring steel, this ring offers excellent tensile strength and elasticity. This allows it to be expanded or compressed during installation and then return to its original shape to provide a secure hold. The "40 Es" designation typically refers to the specific sizing standard (often metric) required for the shaft or housing groove it is designed to fit. Using non-OEM substitutes for such precision parts can lead to loose fits, mechanical play, or premature failure of the assembly.

This part is commonly found in the drive systems, wire feed units, or internal mechanical structures of ESAB welding power sources and feeders. Maintenance professionals and MRO specialists rely on genuine ESAB parts to maintain the factory specifications of their equipment. Whether you are performing routine maintenance or an emergency repair, the 0749341040 retaining ring provides the reliability needed to minimize downtime and maintain operational efficiency.

Technical Reliability

Industrial welding environments subject equipment to vibration, heat, and mechanical stress. The ESAB 0749341040 is engineered to withstand these conditions without losing its seating. Its corrosion-resistant finish helps protect it from the typical workshop environment, ensuring that the mechanical integrity of your welding machine remains uncompromised over time.
