Product Description

The BROWNING 1002575 is a two-groove, quick-detachable (QD) bushed V-belt sheave designed for industrial belt drive applications. Identified by manufacturer part number 2TB94, it accepts A, B, and 5V belt trade sizes with a belt pitch A diameter of 9.0 inches and a belt pitch B diameter of 9.4 inches. The outside diameter measures 9.75 inches. Bore diameter ranges from 0.75 inches minimum to 2.6875 inches maximum, accommodating a wide range of shaft sizes via the Q1 bushing style. Constructed from iron, this sheave delivers durable, long-service performance in power transmission systems found in HVAC, blower, pump, and general mechanical drive installations.

This sheave is intended for use in commercial and industrial power transmission setups where A, B, or 5V V-belts are specified. Common installation scenarios include belt-driven blower assemblies, fan arrays, pump drives, and similar equipment in mechanical rooms or rooftop HVAC units. The QD bushing design allows for straightforward shaft mounting and removal without specialized tooling, making it a practical choice for service technicians performing routine belt drive maintenance or equipment upgrades.

Installation Notes

Installation is typically performed by a licensed millwright, HVAC mechanic, or qualified maintenance technician. De-energize and lock out the drive system before removing or mounting the sheave. Verify shaft diameter falls within the 0.75 to 2.6875 inch bore range before selecting the appropriate Q1 QD bushing. Confirm belt alignment and tension according to the belt manufacturer specifications after installation to prevent premature wear.
