Browning 1079151 Q Type Cast Iron Idler Bushing

Product Description

The BROWNING 1079151 is a cast iron Q type idler bushing designed for use in belt drive systems where a non-driven pulley or sheave requires a secure, low-friction mount. This bushing accepts a 1-3/4 inch bore and measures 4-1/8 inches in outside diameter, providing the dimensional fit needed for H, P, and Q style idler pulley assemblies. At 5.5 pounds, the cast iron construction delivers the mass and rigidity required to maintain alignment under continuous belt tension. This part is installed by millwrights, mechanical contractors, and industrial maintenance technicians working on conveyor, power transmission, and HVAC blower drive systems.

The BROWNING 1079151 is suited for industrial and commercial power transmission applications where Q type idler bushings are specified. It is compatible with H, P, and Q style idler pulley and sheave assemblies. Typical installation scenarios include conveyor belt systems, fan drives, and other belt drive configurations requiring a fixed or adjustable idler point. The cast iron body withstands the sustained radial loads and vibration common in continuous-duty drive systems.

Compatibility

Designed for use with H, P, and Q style idler bushing assemblies in industrial and commercial belt drive systems. Specific compatible model numbers were not provided in the product data.

Installation Notes

Installation is typically performed by millwrights or qualified mechanical maintenance technicians. Ensure all drive power is locked out and tagged out before removing or installing any bushing or pulley component. Verify bore, outside diameter, and keyway dimensions against the existing assembly before installation. Follow applicable ANSI and OSHA lockout/tagout procedures for power transmission equipment service.
