R2 Type Split Taper Bushings
R2 Type Split Taper Bushings are mechanical components designed for mounting pulleys, sprockets, sheaves, or other power transmission devices onto a shaft securely and accurately. These bushings are split, conical-shaped sleeves made from durable materials such as steel or cast iron, offering a tapered fit for enhanced stability. They utilize a split design that allows them to compress tightly around the shaft as bolts are tightened, ensuring a secure, vibration-resistant fit with minimal slippage. This design also facilitates easy installation, removal, and repositioning without needing specialized tools. R2 bushings are commonly used in industrial machinery, conveying systems, and heavy-duty applications, accommodating various shaft sizes and keyways for versatile use.

Key Features of R2 Type Split Taper Bushings
R2 type split taper bushings are designed for secure and efficient power transmission in industrial applications. Here are the key features:
- Double Split Barrel Design: The R2 bushing features a double split barrel, allowing easy installation and removal without shaft damage. This design enhances clamping force, ensuring a tight, concentric fit on the shaft for reliable performance in high-torque applications.
- Solid Flange Construction: Equipped with a solid flange, the R2 bushing maintains concentricity, reducing vibration and wear. This robust structure supports the bushing’s alignment, ensuring smooth operation and extending the lifespan of connected components like sprockets or pulleys.
- Key-to-Key Drive System: The bushing incorporates a key-to-key drive, with keys on both shaft and hub. This provides a positive, high-strength drive, preventing slippage and ensuring efficient power transfer under heavy loads or dynamic conditions.
- 3/4" Per Foot Taper: The R2 bushing’s barrel has a 3/4" per foot taper, creating a self-locking mechanism. This taper ensures a secure grip on the shaft, minimizing axial movement and enhancing mechanical locking during operation.
- Inch and Metric Bore Options: Available in a wide range of inch and metric bore sizes, the R2 bushing offers versatility for various shaft dimensions. This adaptability makes it suitable for diverse industrial applications, ensuring compatibility with global standards.
- External Key and Keystock Inclusion: An external key provides additional drive security, and keystock is included for shallow key sizes. This feature reinforces the bushing’s hold, reducing the risk of rotational slip in demanding, high-vibration environments.
Common Troubleshooting of Split Taper Bushings
Split taper bushings are used to mount pulleys, sprockets, or other components onto shafts securely. Troubleshooting issues with them often involves addressing improper installation, misalignment, or wear. Here are common problems and their solutions:
- Bushing Won't Fit on Shaft
- Cause: Incorrect bushing size, burrs on the shaft, or debris.
- Solution: Verify bushing and shaft dimensions match specifications. Deburr the shaft with fine emery cloth and clean both surfaces. Ensure no grease or oil interferes with the fit.
- Component Slips on Shaft
- Cause: Insufficient torque on cap screws, worn bushing, or keyway damage.
- Solution: Tighten cap screws progressively in a star pattern to the manufacturer’s recommended torque (use a torque wrench). Inspect bushing and key for wear; replace if damaged. Ensure the key is properly seated.
- Difficulty Removing Bushing
- Cause: Corrosion, overtightened screws, or improper removal technique.
- Solution: Apply penetrating oil and let it sit. Loosen cap screws and insert them into the removal (jacking) holes. Tighten screws alternately to push the bushing out. Tap lightly with a soft mallet if needed, avoiding damage.
- Vibration or Wobble During Operation
- Cause: Misalignment, uneven screw torque, or damaged bushing/shaft.
- Solution: Check alignment between the shaft and component. Retorque screws evenly. Inspect bushing and shaft for wear or distortion; replace if necessary.
- Premature Wear or Cracking
- Cause: Overloading, improper installation, or material fatigue.
- Solution: Confirm the bushing is rated for the load and application. Ensure proper installation with correct torque values. Replace with a higher-grade bushing if needed.
