Item Name: Covington Parts - Arbor Shaft 1" x 18" SKU: COVCAS018 Description: The Covington Arbor Shaft 1"x18" is a precision-engineered replacement shaft designed for Covington faceting and lapidary equipment. This shaft is constructed from high-quality steel and measures 1 inch in diameter with an 18-inch length. The arbor shaft serves as the central rotating component that holds and drives the cutting wheel or grinding surface in faceting machines. It is compatible with the Covington TSA series equipment and is engineered to maintain precise alignment and balance during extended cutting operations. How it is used: In lapidary work and stone faceting, the arbor shaft is the critical component that rotates to power the cutting or grinding wheel. When properly installed in a Covington faceting machine, the shaft receives rotational force from the motor and transfers it to the wheel, allowing artisans to cut precise facets on gemstones and other materials. The shaft's robust construction ensures stability during high-speed operation, which is essential for achieving clean, accurate cuts. This replacement shaft is used when the original shaft becomes worn, damaged, or requires maintenance. Dimensions: 1" Shaft Diameter 18" Length 8 Lbs.
