Tapered Lock Bushings Description
Precision Shaft Fixing Solutions for Industrial Power Transmission
Taper lock bushings provide a secure, concentric method of mounting pulleys, sprockets, sheaves, and couplings onto rotating shafts. By using a precision-machined taper, the bushing grips both the shaft and hub evenly, ensuring reliable torque transmission with minimal vibration.
What Is a Taper Lock Bushing?
A taper lock bushing is a split, tapered sleeve that fits between a shaft and a driven component. When tightened using mounting screws, the taper creates a strong clamping force that locks the hub and shaft together without the need for custom machining or permanent fastening.
This design allows for easy installation, accurate alignment, and quick removal during maintenance or replacement.
Typical Applications
Taper lock bushings are widely used across industrial and commercial equipment, including:
Electric motors
Conveyors and material handling systems
Pumps and compressors
Fans and blowers
Gearboxes and drive assemblies
Their versatility makes them suitable for both light-duty and heavy-duty applications.
Materials & Construction
Manufactured from high-grade close-grain cast iron (GG25)
Precision-machined taper for uniform load distribution
Designed for both metric and imperial shaft sizes
Interchangeable with industry-standard taper lock hubs
Material selection and machining accuracy play a critical role in reducing shaft wear and ensuring long service life.
Key Features & Benefits
Secure, concentric shaft mounting
High torque transmission capability
Reduced vibration and backlash
Simple installation and removal
No reboring of hubs required
Compatible with a wide range of standard pulleys and sprockets
Installation & Removal Guidelines
The following procedure outlines general industry-accepted practices for taper lock bushing installation and removal.
Installation
Ensure the shaft, bushing bore, and hub surfaces are clean and free from oil, grease, or debris.
Insert the bushing into the hub and align the mating holes.
Lightly thread the mounting screws into the designated holes without fully tightening.
Slide the assembled hub and bushing onto the shaft to the desired position.
Tighten the screws gradually and evenly, alternating between screws to draw the bushing into the hub.
Continue tightening until the assembly is firmly seated and the torque remains consistent.
After installation, unused holes may be lightly greased to protect against corrosion.
Removal
Loosen and remove all mounting screws.
Reinsert the screws into the threaded holes provided for removal.
Tighten the screws evenly to push the bushing out of the hub taper.
Once released, slide the assembly off the shaft.
Important: Do not apply lubricants or anti-seize compounds to the tapered surfaces during installation, as this may reduce holding force.
