Browning 1078294 Taper Bushing

The Browning 1078294 is an H-series split taper bushing engineered for high-torque mechanical power transmission in HVACR systems. Specifically designed with a 13/16" bore diameter, this precision component features a double split barrel that ensures true concentricity and a powerful 360-degree clamp fit on the shaft. This uniform radial clamping force is critical for high-radial load applications, such as securing blowers, fans, and pulleys, as it significantly reduces vibration and prevents shaft marring compared to standard setscrew hubs. Built from robust sintered steel or ductile iron, the 1078294 incorporates a 3/4" per foot self-locking taper, delivering mechanical locking that maintains a rigid connection between the shaft and the multiple groove sheave or industrial hub.

For the veteran technician, this split taper bushing 13/16 bore is a reliable solution for fractional horsepower drives. It includes a solid flange designed to prevent bore deformation during high-tension installations and utilizes two 1/4" x 3/4" cap screws for secure mounting. The integrated 3/16" x 3/32" keyway provides a positive mechanical drive, ensuring that torque is transmitted through the key rather than placing unnecessary stress on the mounting hardware. Its compatibility with various Browning sheaves and pulleys makes it a standard inventory item for commercial equipment maintenance and mechanical repairs.

• Concentric Shaft Locking: The double split barrel design ensures the bushing remains centered, minimizing runout and extending the operational life of bearings and belts.
• Self-Locking Taper: Features a 3/4 inch per foot taper that creates a secure, vibration-resistant friction connection for stable torque transmission.
• Durable Construction: Manufactured from high-strength sintered steel to withstand demanding industrial environments and frequent start-stop cycles.
• Simplified Maintenance: The split design allows for easy installation and removal without the need for specialized pullers, reducing system downtime.

• What is the torque specification for the mounting screws? The 1/4" cap screws on this H-series bushing should be tightened sequentially to 95 lb-in to ensure proper clamping force.
• Is this bushing interchangeable with QD-style bushings? No, split taper bushings utilize a specific flange and bolt pattern that is usually not interchangeable with Quick Detachable (QD) or Taper-Lock systems.
• Does the H 13/16 bushing require an external key? While many Browning bushings use an external key, the G and H series rely on the internal shaft keyway and the friction of the tapered barrel for drive connection.
