Taper lock bushings are mechanical components designed to securely connect hubs to shafts using a tapered fit. They are widely used in power transmission systems for their reliability, ease of installation, and ability to handle high torque loads. These bushings consist of a flanged bushing with a tapered outer surface and a matching tapered sleeve, which, when tightened with screws, creates a strong grip on the shaft without the need for additional machining. This makes them ideal for applications in industries such as manufacturing, agriculture, and automotive, where quick assembly and disassembly are essential. The taper lock design ensures minimal slippage and vibration, enhancing the lifespan of machinery.
Our taper lock bushings come in a range of sizes to meet different industrial needs. Below is a detailed table of specifications, including dimensions, materials, and load capacities. Ensure to select the appropriate bushing based on your shaft diameter and application requirements.
| Bushing Size | Bore Diameter (mm) | Outside Diameter (mm) | Length (mm) | Material | Max Torque (Nm) | Weight (kg) |
|---|---|---|---|---|---|---|
| 1008 | 12-40 | 62 | 55 | Hardened Steel | 250 | 0.5 |
| 1108 | 15-45 | 68 | 60 | Cast Iron | 300 | 0.7 |
| 1210 | 20-50 | 75 | 65 | Hardened Steel | 400 | 1.0 |
| 1310 | 25-60 | 82 | 70 | Cast Iron | 500 | 1.2 |
| 1610 | 30-70 | 90 | 75 | Hardened Steel | 600 | 1.5 |
| 2012 | 40-80 | 105 | 85 | Cast Iron | 800 | 2.0 |
Note: Bore diameters are adjustable within the specified range. All bushings include standard screws for installation. For custom sizes or materials, contact our support team.
For removal, simply loosen the screws and tap the bushing gently with a soft hammer to release the taper lock.
Taper lock bushings are utilized in a wide array of machinery and systems, including:
Their ability to handle high loads and resist environmental factors makes them suitable for both indoor and outdoor applications.
What is the main advantage of using a taper lock bushing over a standard bushing?
The primary advantage is the secure grip achieved through the tapered design, which eliminates the need for keyways or set screws, reducing the risk of slippage and simplifying installation.
How do I determine the correct size of taper lock bushing for my application?
Measure the shaft diameter and refer to our size chart above. Choose a bushing with a bore range that includes your shaft size, and consider the torque requirements based on your machinery's specifications.
Can taper lock bushings be reused after removal?
Yes, they can be reused multiple times if not damaged during removal. Inspect for wear or deformation before reinstallation to ensure performance and safety.
What maintenance is required for taper lock bushings?
Regular inspection for tightness and signs of wear is recommended. Lubrication is not typically needed, but keep the area clean to prevent debris from affecting the taper fit.
Are there temperature limitations for these bushings?
Standard models operate effectively in temperatures from -20°C to 120°C. For extreme conditions, special materials or coatings can be requested.
How do I prevent the bushing from loosening over time?
Ensure proper installation with even torque on all screws. Use thread-locking compounds on screws if vibration is a concern, and perform periodic checks during operation.
Can I use taper lock bushings with non-standard shaft materials?
Yes, but ensure the shaft surface is smooth and free of imperfections. For soft materials like aluminum, consider using a hardened sleeve to prevent damage.
What is the typical lifespan of a taper lock bushing?
Lifespan varies based on usage, load, and environment, but with proper installation and maintenance, they can last several years in most industrial applications.
