Case Study: Seward Screw’s Precision Steel Pivot Shafts Save a Motorcycle Manufacturer $400,000 Annually

Seward Screw collaborated with our customer, a manufacturer of motorcycles, in the re-design of their existing “pivot shaft” and “pivot bushing/nut” parts to solve application issues with loosening and to reduce the cost of the rear suspension’s pivot assembly system.

The pivot shafts were being machined from a costly pre-hardened 4140 alloy steel. The external thread design changed to an internal thread design. The resulting changes to the joint enabled us to suggest a lower cost, faster machining material grade that resulted in a significant cost reduction.

The two mating pivot bushings/nuts were being machined from bar stock, followed by an application of Scotch-Grip™ thread adhesive applied to the internal threads. The internal threads and thread adhesive were no longer needed and we offered a cold-formed part as a replacement for the costly machined part. This resulted in another significant cost savings over the slower machining process.

The resulting changes in design, manufacturing processes and materials saved our customer 30% or approximately $400,000 annually.
