375294 - Tweco Wire Feeder Drive Roll Spacer

Genuine Tweco Replacement Spacer for Wire Feeders

The Tweco 375294 Spacer, Drive Roll is a specialized replacement part engineered for specific Tweco wire feed assemblies. In high-performance welding operations, the mechanical integrity of the wire delivery system is paramount. The drive roll assembly is the heart of this system, pushing the electrode through the liner to the contact tip. This spacer serves a critical function: it acts as a mechanical shim to position the drive roll axially along the drive shaft. Without this correct spacing, the wire groove on the roll may not align with the inlet and outlet guides, causing friction, shaving of the wire, and feeding instability.

Constructed from high-grade metal, this spacer is built to resist deformation under the clamping pressure of the drive roll retention mechanism. It is an authentic OEM part, ensuring compatibility with your existing Tweco hardware. Using non-standard or improvised spacers can lead to uneven pressure on the drive rolls, which not only affects weld quality but can also damage the drive motor bearings over time due to unbalanced loads. Investing in the correct part protects your larger equipment investment.

This component is ideal for welding technicians and maintenance personnel who demand reliability. When servicing your wire feeder—whether changing wire sizes, replacing worn drive rolls, or performing a deep clean—having the correct spacers on hand is essential. The 375294 part number corresponds to the specific dimensions required for your Tweco feeder model, eliminating the guesswork associated with universal parts.

Technical Reliability

Wire feeding problems are often misdiagnosed as liner or tip issues when the root cause lies in the drive assembly alignment. By utilizing the Tweco 375294, you eliminate alignment as a variable. This part is machined to tight tolerances, ensuring that when the drive roll cap is tightened, the assembly is rigid and perfectly centered. Ensure your shop is stocked with these essential small parts to prevent minor maintenance needs from becoming major production stoppages.
