Coupler .750-20 x .750 Weld-On

The Coupler .750-20 x .750 Weld-On from Woodward Machine is a precision shaft coupling designed for welded driveline and mechanical assembly applications where direct power transfer and structural rigidity are essential. This product is ideal for fabricating custom drivetrains, building race-car transmission mounts, or assembling heavy-duty mechanical systems.

Engineered for reliability in high-vibration environments, this weld-on coupler eliminates slip and play that bolted alternatives introduce. It features a .750-inch bore diameter on both ends, which is compatible with common shaft sizing in automotive and industrial applications. The design ensures a permanent connection once properly MIG or TIG welded, making it suitable for sealed or high-temperature environments.

This coupler is particularly beneficial for custom transmission adapters, driveshaft extensions, and fabricated engine accessory drives. Its compact length of 3.05 inches helps maintain a minimal assembly footprint, which is critical in tight engine bays where space is limited.
