Split tapered locking bushings are essential components for securely mounting components like sprockets, gears, and pulleys onto shafts. Ensuring a precise fit and reliable torque transfer is critical for the efficient and safe operation of machinery. Selecting the appropriate bushing type and size directly impacts performance and longevity.
For pulleys that require a H style bushing, more secure than a standard one-piece pulley.
Easy Install: This bushing inserts into the center of the pulley and slides over the shaft. As you tighten down the bolts on the H bushing it will tighten down on the shaft.
As you tighten down the bolts on the H bushing it will tighten down on the shaft. This style is much more secure than a standard 1 piece pulley. This listing includes an H bushing to fit on a keyed 1-1/8" shaft.

How to Choose the Best Split Tapered Locking Bushings
Understanding Split Tapered Locking Bushings
These bushings are designed to create a tight interference fit between a shaft and a mounted component. They consist of an outer taper and an inner taper, with a split in the outer sleeve. When the mounting component is tightened, the bushing draws inward, securely clamping the shaft.
Key Features to Consider
Material: Bushings are commonly made from cast iron or steel. Cast iron offers good damping properties, while steel provides higher strength and wear resistance.
Bore Sizes: Bushings are available in a wide range of bore sizes to accommodate different shaft diameters. Ensure the bore size matches your shaft precisely.
Outer Diameter and Flange: The outer diameter and flange dimensions must be compatible with the mounting component (e.g., pulley or sprocket).
Mounting Holes: Check the number and spacing of mounting holes on the component to ensure they align with the bushing's flange.
Type of Split: Some bushings have a single split, while others have multiple splits for even greater clamping force and concentricity.
Applications and Selection
These bushings are used across various industries, including manufacturing, agriculture, and material handling. They are ideal for applications requiring reliable power transmission and easy installation/removal. When selecting a bushing, consider the torque requirements, operating environment, and the specific dimensions of both the shaft and the component being mounted.
Installation and Maintenance
Proper installation is crucial for optimal performance. Ensure the shaft and component bores are clean and free of debris. Lubricate the tapered surfaces lightly before assembly. Tighten the mounting cap screws evenly in a star pattern to achieve the specified torque. Regular inspection for wear or damage is recommended.
Frequently Asked Questions
What is the purpose of a split tapered locking bushing?
A split tapered locking bushing is used to securely mount components like pulleys or sprockets onto a shaft. It creates a precise, zero-backlash interference fit, ensuring reliable torque transmission and preventing slippage.
How do I determine the correct bore size?
The bore size of the bushing must precisely match the diameter of the shaft it will be mounted on. Measure your shaft accurately and select a bushing with a corresponding inner bore diameter.
What is the difference between cast iron and steel bushings?
Cast iron bushings offer good vibration damping characteristics, making them suitable for applications where noise reduction is important. Steel bushings, on the other hand, provide superior strength and wear resistance for heavy-duty applications.
Can I reuse a tapered locking bushing?
While it's possible to reuse a bushing, it's generally recommended to use a new one for critical applications. Repeated installations can slightly alter the bushing's dimensions and affect the optimal interference fit.
What tools are needed for installation?
Installation typically requires a wrench or socket set to tighten the cap screws. Ensure you have the correct size sockets for the cap screws and a torque wrench to achieve the recommended tightening specifications.
