Browning B 1 7/8 Bushing

Browning B 1 7/8 Bushing

As a veteran contractor, you know that the Browning B 1 7/8 Bushing is a staple in high-torque industrial and HVACR drive systems. This B Series Split Taper Bushing is engineered with a 1 7/8 inch finished bore and a standard 1/2 inch x 1/4 inch keyseat, providing a robust mechanical connection for sheaves, sprockets, and pulleys. The split taper design features a 3/4 inch per foot taper and a double-split barrel that ensures true concentricity to the shaft, effectively eliminating the vibration and slippage common with low-grade alternatives. Constructed from high-quality sintered steel or ductile iron, it utilizes a key-to-key drive system that transmits power through both the shaft and the hub, maximizing torque carrying capacity without placing undue stress on the cap screws. Designed for versatility, this B series bushing is fully interchangeable with other industry-standard split taper systems, making it a reliable choice for critical fan, blower, and pump applications.

Key Benefits:
  • Concentric Shaft Gripping: The double-split barrel provides 360-degree clamping force, preserving shaft integrity and reducing harmonic vibration.
  • High Torque Transmission: Features a solid flange and positive drive keyway to handle heavy start-stop loads in HVAC blowers.
  • Simplified Maintenance: Facilitates rapid installation and removal using standard cap screws, minimizing downtime during motor or drive servicing.
  • Universal Compatibility: Fits all Browning "B" series hubs, ensuring a precise match for broad drive requirements.
Common Questions:

Is this bushing compatible with standard QD sheaves?
No, the Browning B 1 7/8 is a split taper series bushing and is only compatible with hubs specifically machined for the B series taper. It is not interchangeable with QD (Quick Disconnect) or Taper-Lock styles.

What is the required torque for the mounting bolts?
For the B series, the typical wrench torque is 192 in-lbs. Always use a torque wrench and tighten the 5/16 inch x 1 1/4 inch cap screws in a circular pattern to ensure even seating.

Can I use this on a shaft without a keyway?
While the split taper design provides significant friction-based gripping, the 1/2 inch x 1/4 inch keyway positioning is critical for high-torque HVACR applications to prevent high-speed rotational slippage.
