Overview
The Browning Q1-1-15/16 split taper bushing is a precision mechanical power transmission component manufactured by Regal Rexnord. Designed for high-torque industrial applications, this bushing delivers reliable shaft mounting for sheaves, sprockets, pulleys, and other power transmission equipment. The split taper design provides self-locking capability and requires no set screws for installation, making it ideal for maintenance and retrofit work.
Key Features
- Solid Flange and Double Split Barrel: Ensures superior concentricity and load distribution across the shaft.
- Key-to-Key Drive: External keys on both shaft and bushing provide the strongest possible drive with zero torque on cap screws.
- 3/4″ per Foot Self-Locking Taper: Delivers the highest degree of mechanical locking without requiring set screws or adhesives.
- Lifetime Warranty: Browning guarantees free replacement if the bushing ever fails due to manufacturing defects.
- Quick Installation: Split design allows removal and installation without shaft removal, reducing downtime.
