Browning 1026335 Single Groove Sheave 3.4in Od 7/8in Bore

Product Description

The BROWNING 1026335 is a finished bore single groove sheave designed for V-belt drive systems in industrial and mechanical applications. Constructed from cast iron, this sheave features a 3.4 inch outer diameter and a 7/8 inch finished bore, ready for direct shaft mounting without additional machining. The groove is sized for Type 4L/A or Type 3L V-belts, making it a straightforward replacement or new-installation component for light-duty drive assemblies. At 0.85 pounds, it is compact and suited for confined drive configurations. Licensed mechanical contractors and industrial maintenance technicians are the typical installers.

This sheave is used in residential and light commercial mechanical drive systems where a single-groove V-belt configuration is required. Typical applications include blower drives, fan assemblies, pump drives, and small power transmission setups that rely on Type 4L, Type A, or Type 3L V-belts. The 21/32 inch groove width and 7/8 inch finished bore suit standard shaft sizes found in these common drive arrangements.

Installation Notes

Installation is typically performed by a licensed millwright, mechanical contractor, or qualified maintenance technician. Shut down and lock out all power to the drive system before removing or installing any sheave. Verify shaft diameter and keyway dimensions match the finished bore before pressing or sliding the sheave onto the shaft. Align the sheave with its mating pulley within manufacturer-recommended tolerances to avoid premature belt wear.
