B Type Split Taper Bushings
A B Type Split Taper Bushing is a mechanical component used to mount pulleys, sprockets, or sheaves onto a shaft in power transmission systems. It features a double-split barrel and a solid flange, with a 3/4-inch per foot taper for a self-locking grip. The dual-split design enhances concentricity, reducing vibration, and allows easy installation and removal. Keyed to both the shaft and hub, it ensures a secure, high-torque connection, ideal for applications requiring precise alignment and stability.

Key Benefits of B Type Split Taper Bushings
B-type split taper bushings offer several key benefits for industrial applications. Here are the primary advantages:
- Enhanced Shaft Grip and Concentricity: B Type split taper bushings feature a double-split barrel design that ensures superior concentricity to the shaft, providing a secure grip. This reduces vibration and enhances stability, making them ideal for high-torque applications where precise alignment is critical for optimal performance and equipment longevity.
- Easy Installation and Removal: The split design allows for straightforward installation without requiring extensive disassembly of machinery. By tightening bolts, the bushing clamps securely, and removal is simplified by loosening fasteners, minimizing downtime and maintenance efforts in industrial settings.
- Versatile Bore Size Compatibility: B Type bushings accommodate a wide range of bore sizes, from 3/8" to 7-1/4", offering flexibility for various shaft diameters. This adaptability reduces inventory needs and enables seamless integration across diverse machinery and applications.
- High Torque Transmission: With a wrench torque capacity of 192 pounds, these bushings excel in transmitting high torque. The key-to-key drive, with keys on both shaft and hub, ensures a robust, slip-free connection for demanding operations.
- Durability and Reliability: Constructed from premium materials like steel or cast iron, B Type bushings resist wear and maintain performance under harsh conditions. Their solid flange design enhances durability, ensuring long-term reliability and reducing replacement frequency in heavy-duty environments.
- Interchangeability Across Manufacturers: B Type split taper bushings are standardized, allowing interchangeability between brands like Browning and Martin. This compatibility simplifies sourcing and replacement, providing cost-effective solutions without compromising quality or performance in various industrial applications.
Split Taper Bushings vs. QD Bushings
Split Taper Bushings are designed with a double-split barrel and a flanged outer diameter, keyed both internally to the shaft and externally to the component (e.g., pulley or sprocket). The dual splits enhance grip strength, and the conical taper provides a secure, self-locking connection, ideal for high-torque or high-vibration applications like industrial machinery. They allow easy installation and removal, adapting to various shaft sizes without needing a precisely bored component, reducing inventory needs. Their robust design ensures stability even if fasteners loosen, making them suitable for demanding environments requiring precision and durability.
QD (Quick Disconnect) Bushings feature a single split through the flange and taper, with a flanged outer diameter for securing to components. They excel in applications needing frequent maintenance due to easy installation and removal via cap screws, which enhance holding power. Common sizes include SD, SK, and JA. QD bushings are versatile, fitting multiple shaft sizes, but their flange design may require more radial space than split taper bushings. They’re less suited for extreme torque compared to split taper bushings but are preferred in settings prioritizing quick component changes, like conveyor systems.
Key Differences: Split taper bushings offer superior torque resistance and stability due to their double-split and higher conical taper, while QD bushings prioritize ease of maintenance. Choosing between them depends on torque requirements, maintenance frequency, and space constraints.
