0211103035 - ESAB 12x40mm Slotted Spring Pin

Precision Engineering for Industrial Reliability

The ESAB 0211103035 Spring Pin is a critical mechanical component designed to maintain the structural integrity and operational efficiency of ESAB welding machinery. Often referred to as a slotted spring pin or roll pin, this fastener is engineered to secure machine components by exerting continuous radial pressure against the walls of the installation hole. Measuring 12mm in diameter and 40mm in length, it is manufactured to strict tolerances to ensure a secure, vibration-resistant fit that is essential for equipment operating in harsh industrial environments.

Spring pins are unique in their ability to absorb shock and vibration, which are common in heavy-duty welding operations. Unlike solid dowel pins, the slotted design allows the pin to compress during insertion and then expand, locking it firmly in place without the need for threading or secondary retention methods. This specific ESAB part is crafted from high-grade spring steel, heat-treated to provide the optimal balance of hardness and flexibility. This ensures that the pin can withstand significant shear loads without deforming or fracturing, thereby protecting the more expensive components of your welding assembly.

Using genuine OEM parts like the ESAB 0211103035 is vital for maintaining the manufacturer's specifications. Generic pins may lack the precise metallurgical properties or dimensional accuracy required, leading to loose fits, premature wear, or even catastrophic mechanical failure during operation. Whether used in wire feed mechanisms, chassis assembly, or articulating joints, this pin represents the quality and reliability professionals expect from the ESAB brand.

Technical Specifications and Application

The 12x40mm form factor is a standard metric size used across various ESAB product lines. Maintenance personnel should verify the specific part number in their equipment's service manual before installation. Proper installation requires the use of a roll pin punch of the appropriate size to prevent damage to the pin end or the host material. By choosing this authentic ESAB component, you ensure that your equipment remains compliant with safety standards and performs at peak efficiency.
