88663 Flat Idler Pulley for Mower Decks, 5" Flat Diameter, 5/8" Bore

Key features

• Precision-Engineered Design - With a 1-1/16" belt groove, 5/8-inch bore, and 5-3/4-inch overall outside diameter (OD), this idler pulley is built for smooth compatibility with a variety of belt-driven systems. It features symmetrical bore adapters that fit multiple shaft sizes, ensuring a secure and accurate fit, while its angled flanges help guide the belt, reducing wear and boosting efficiency
• Smooth Performance - Designed for low friction and longevity, this pulley comes with a sealed radial single-row bearing that keeps rotation smooth and reliable, while its precision-balanced structure minimizes vibration for quieter and more efficient operation
• OEM Replacement - A direct replacement for Bush Hog (88663), Ariens (02885600), and Locke Turf (02885600), making it a hassle-free swap for your existing power transmission system
• Durable Steel Construction - Made from high-quality steel for strength and durability, this pulley is built to last, and its black-painted finish adds corrosion resistance, so it can withstand tough working conditions with ease
• Please Note - Some buyers may expect the “5-inch” size to refer to the total outside diameter. In fact, 5 inches refers to the flat diameter, which is the area where the belt actually contacts and runs. The total outside diameter, including the flanges, is approximately 5-3/4 inches (5.75"), which is normal and within specifications
• Buy with Confidence - 1-year warranty and 30-day return policy available. We strive to improve efficiency, reduce costs, and save time, so you can focus on what matters most. Find your parts here
