SKF 6203 1/2" Bearing

SKF 6203 1/2" Bearing - The half-inch bore that quietens a tired motor. Some pump motors run an imperial shaft, and that's where the half-inch 6203 earns its keep. It carries the same 40mm outer body and 12mm width as the standard 6203, but with a 12.7mm (½-inch) bore sized for those motors. Drop a fresh one in and the rumble, drag and heat of a worn bearing give way to a motor that spins free again. Imperial and metric 6203s look identical until you measure the bore, so check the number stamped on your old bearing before ordering. A small part with an outsized effect on how your pump sounds. Features Imperial Shaft Fit: Sized for pump motors built around an imperial shaft, where a metric 6203 won't seat correctly. Deep Groove Construction: Soaks up the radial and thrust loads of a spinning shaft, keeping the motor smooth and quiet. Match Before You Fit: Looks identical to a metric 6203 — confirm the bore against your old bearing first. Specifications Bore (Inner Diameter): 12.7mm (½"). Outer Diameter: 40mm. Width: 12mm. Construction: Single-row deep groove ball bearing.
