Browning 1033208 Two Groove Cast Iron Sheave 1 in Bore

Product Description

The BROWNING 1033208 is a finished bore, two-groove cast iron sheave designed for use with B-section or A-section V-belts in belt-drive power transmission applications. It features a 1 inch finished bore diameter and a 3.15 inch outside diameter, with a belt pitch diameter of 2.8 inches for B-type belts and 2.4 inches for 4L or A-type belts. The through-bore length measures 1-31/32 inches. Cast iron construction provides durability under continuous load and resists wear in demanding drive system environments. This sheave is installed by HVAC technicians, millwrights, and mechanical contractors on motor and driven-shaft applications.

This sheave is suited for residential and light commercial HVAC systems, fans, blowers, and general industrial belt-drive assemblies where a two-groove configuration is required. The finished bore is ready for installation without additional machining, making it a direct-fit solution for retrofit and new construction drive setups. Typical applications include belt-driven air handlers, exhaust fans, and centrifugal blowers where matched dual V-belt arrangements are used to transmit motor power to a driven component.

Installation Notes

Installation should be performed by a qualified HVAC technician, millwright, or mechanical contractor. De-energize and lock out the motor before removing or installing any sheave. Verify shaft diameter and keyway dimensions before mounting, and ensure set screws or taper-lock hardware are properly torqued per the shaft and hub manufacturer specifications. Check belt tension and sheave alignment after installation to prevent premature belt and bearing wear.
