Product description

This precision-ground steel shaft serves as a critical pivot point or axle for various moving parts within the Ammco and Ben Pearson lift assembly. It is machined to exact tolerances to ensure a snug fit that minimizes play while allowing for smooth rotation of attached components. The high-quality steel construction provides the necessary shear strength to handle the loads transmitted through the lift's mechanical linkages. Over time, these shafts can become worn, grooved, or bent, which can lead to misalignment and increased friction in the system. Installing a fresh pivot shaft is an important part of any major lift overhaul, ensuring that all moving parts operate with factory-level precision.

Product highlights

• Precision Machining: Ground to exact diameter specifications to provide a perfect interface for pulleys or pivot linkages.
