Description
The Nordyne 920338 is an SDS Series Quick-Detachable (Q-D) taper-lock bushing engineered for secure, precise mounting in HVAC drive and power transmission assemblies. Featuring a 1-1/4″ bore and a 1/4″ x 1/8″ keyseat, this bushing delivers a tight, concentric fit on shafts while allowing fast installation and removal without special tooling — minimizing downtime during maintenance or equipment changeouts.
Product Overview
Q-D (Quick-Detachable) bushings use a split, tapered design that locks firmly onto a shaft when tightened and releases cleanly when the clamping screws are backed out. The SDS series is a compact, light-duty bushing profile commonly used in smaller sheaves, pulleys, and sprockets found throughout commercial and residential HVAC equipment.
