Castair Replacement Wheel 10X2X1/2" W10x1.5x.5

The Castair W10x1.5x.5 is a replacement wheel for Castair air compressor units — 10" outer diameter, 2" wide tread, 1/2" axle bore. This is the right wheel when a compressor's existing wheel is damaged, worn through, or when you're reconditioning a used Castair unit to return it to mobile service. The 1/2" bore fits standard 1/2" axle rod, and the 10" diameter gives a compressor adequate ground clearance and rollability on typical shop and garage floors. When You Need This Wheel Compressor wheels get damaged in predictable ways: the rubber tread wears flat from years of dragging rather than rolling, the plastic hub cracks from impact or overloading, or the bearing inside seizes from lack of lubrication and the wheel stops rolling entirely. Any of these conditions turns a mobile compressor into a fixed installation — which is fine if that's what you want, but not if you need the unit to move. The W10x1.5x.5 is a $15.40 fix that restores full mobility. This wheel is also useful when reconditioning a used Castair compressor purchased at auction or second-hand. Used units often have damaged wheels from previous operators — replacing both wheels brings the unit back to presentable, functional condition. Key Specifications Outer Diameter: 10 inches Tread Width: 2 inches (listed as 10X2X1/2 in the product name) Axle Bore: 1/2 inch — fits 1/2" axle rod Application: Castair portable and semi-portable air compressor units with 10" wheel specification OEM Castair Part: Factory-specification replacement wheel W10x1.5x.5 vs. W10x3x.75 Castair offers two wheel sizes in this lineup. The choice between them depends on your compressor's original wheel spec: W10x1.5x.5 ($15.40) — 10" OD x 2" wide x 1/2" bore — narrower tread, smaller axle W10x3x.75 ($33.88) — 10" OD x 3" wide x 3/4" bore — wider tread, larger axle bore Match the replacement to your original wheel dimensions. Measure the axle rod diameter before ordering — installing a 1/2" bore wheel on a 3/4" axle requires a bushing, and installing a 3/4" bore wheel on a 1/2" axle is loose and unsafe. When in doubt, measure. Installation Notes Relieve all tank pressure and disconnect from power before any work near the tank or frame Note axle retention method before disassembly — some axles use roll pins, others use cotter pins or snap rings Inspect the axle rod for wear, bending, or corrosion while the wheel is off — a bent axle will wear out the new wheel prematurely Lubricate the axle bore lightly before installation if the wheel uses a plain bearing (no sealed bearing) Reinstall the axle retention hardware securely — a loose wheel on a compressor being rolled is a safety hazard What's in the Box 1x Castair W10x1.5x.5 Replacement Wheel — 10" OD x 2" wide x 1/2" bore Axle retention hardware and mounting hardware are not confirmed to be included. Verify what hardware is needed for your compressor's wheel mounting before ordering.
