Browning 1078344 Taper Bushing

The Browning 1078344 is a professional-grade H-Series Split Taper Bushing designed for high-torque power transmission applications. Featuring a 1 1/16" bore size, this component is engineered to secure sheaves, sprockets, and pulleys to a 1.0625-inch diameter shaft with unmatched concentricity. The double-split barrel design provides a uniform 360-degree clamp fit, effectively eliminating the risk of shaft slippage and reducing vibration in high-RPM HVACR blower systems or industrial drive assemblies. Constructed from sintered steel or ductile iron, the Browning H 1 1/16 utilizes a 3/4" per foot taper to create a self-locking mechanical bond between the shaft and the hub. The solid flange construction ensures the bore remains true under heavy radial loads, protecting your drive components from premature wear. For contractors performing field upgrades, this split taper bushing offers a reliable, keyed connection that simplifies installation and removal compared to standard set-screw alternatives.

• Concentric Alignment: The double-split barrel ensures even clamping force for a balanced, vibration-free drive.
• High Torque Capacity: Features a keyed drive on most applications to handle heavy startup loads without rotational slippage.
• Self-Locking Design: The 3/4" per foot taper provides a secure mechanical lock that won't back off during operation.
• Standardized Compatibility: Fully interchangeable with industry-standard H-series components across various power transmission brands.
• Durable Material: High-strength construction specifically suited for the rigorous demands of commercial HVAC and conveyor systems.

What is the bolt circle diameter for the Browning 1078344?
This H-series bushing is typically designed with a 2" bolt circle diameter and uses two 1/4" x 3/4" cap screws for installation.

Can I use this on a shaft without a keyway?
While the bushing provides significant clamping force on its own, utilizing a keyed shaft is highly recommended for high-torque HVAC applications to ensure full power transfer.

Is the Browning split taper interchangeable with QD bushings?
No, split taper bushings and Quick Detachable (QD) bushings use different taper profiles and mounting patterns; ensure your sheave or sprocket is bored specifically for an H-series split taper.
