Secure Shaft Mounting for Industrial Pulleys & Sprockets
When a pulley, sprocket or coupling hub needs to be mounted securely onto a rotating shaft, selecting the correct taper lock bush is essential.
Taper lock bushes use matching tapered surfaces & a specified fastening arrangement to secure compatible hubbed components. They are used in industrial power transmission systems where accurate shaft mounting, torque transmission & serviceability matter.
For Australian maintenance technicians, machine builders & industrial fitters, the most important buying details are the taper lock series, finished shaft bore & keyway specification.
Industrial Shed lists Finer Power Transmissions taper lock products, including a documented 1610-40 bush with a 40 mm bore & 12 × 8 mm keyway. Use this as an example of how to interpret product specifications, while confirming current collection membership & availability on the individual listing.
How to Choose the Right Taper Lock Bush?
Before ordering, identify the existing bush or the specifications of the mating hub.
Check:
-
Taper lock series: Match the specified series, such as 1610.
-
Shaft bore: Confirm the finished bore matches the shaft diameter.
-
Keyway: Verify the required keyway dimensions.
-
Mating hub: Ensure the pulley, sprocket or hub accepts the bush series.
-
Fasteners: Use the correct installation screws & tightening procedure.
-
Operating torque: Confirm suitability for the transmitted load.
-
Installation space: Check the assembly's dimensional requirements.
-
Environment: Consider corrosion, contamination & vibration.
A bush with the correct bore but the wrong series is not a suitable substitute.
What Is a Taper Lock Bush?
A taper lock bush is a split, tapered mounting component designed to fit a matching tapered hub.
When installed according to the manufacturer's instructions, the connection secures a compatible pulley, sprocket or other hubbed component to a shaft.
Many arrangements also use a shaft key.
The bush, shaft, key & mating hub must all be compatible.
Understanding Taper Lock Bush Sizes
Taper lock bushes are identified using dimensional series codes.
Common examples include 1008, 1210, 1610, 2012 & other established sizes.
The series identifies the bush's mounting family; it does not directly state the shaft bore.
A given series may be offered with multiple bore sizes, depending on the manufacturer.
Always match the series & bore separately.

Taper Lock Bushes for Belt Pulleys
Many industrial belt-drive pulleys use taper lock mounting arrangements.
The selected bush must match the pulley's tapered hub & the shaft diameter.
For related belt-drive components, explore V-Belts – Classical, Wedge & Cogged.
When servicing the drive, inspect pulley alignment, shaft condition & keyway wear before installing a replacement bush.
Taper Lock Bushes for Sprockets
Taper lock bushes can be used to mount compatible sprockets onto shafts.
Correct selection depends on the sprocket hub series, bush bore, keyway & operating load.
Browse Sprockets – Simplex, Duplex, Taper Lock & Idler for related sprocket components.
Confirm chain & sprocket alignment after installation.
Taper Lock Bushes for Coupling Hubs
Some coupling assemblies use taper lock mounting arrangements.
The coupling hub must be designed for the specified bush series.
Do not assume a bush that fits a pulley will automatically fit a coupling hub.
Check the complete coupling manufacturer's mounting requirements.
Finished Bore, Keyway & Shaft Compatibility
A finished-bore taper lock bush is supplied for a specified shaft diameter.
The keyway, where required, must suit the bush & shaft.
For related keyed connection components, explore Keys & Keyways.
Avoid modifying a finished bore or keyway without manufacturer approval.
Taper Lock vs Keyless Locking Bushings
Taper lock bushes use matching tapered mounting surfaces.
Other shaft locking systems may use different clamping or interference arrangements, including keyless designs.
Explore Shaft Collars & Locking Bushings for related mounting options.
These systems are not automatically interchangeable.
Installing a Taper Lock Bush
Correct installation is essential to the performance of the connection.
Before fitting, isolate the machinery & inspect the shaft, bush, hub & keyway.
Follow the manufacturer's instructions for cleaning mating surfaces, positioning components & tightening fasteners.
Use the specified tightening sequence & torque values.
Do not apply lubricants to tapered surfaces unless the manufacturer explicitly instructs you to do so.
Removing a Taper Lock Bush
Many taper lock systems provide threaded removal positions for releasing the bush.
Use the manufacturer's approved removal procedure & correct fasteners.
Avoid striking or forcing components in a way that could damage the shaft or hub.
Common Taper Lock Bush Problems
Warning signs can include looseness, fretting, damaged keyways, corrosion or movement between mounted components.
Possible causes include incorrect sizing, unsuitable loading, damaged mating surfaces or installation errors.
Replacing the bush without investigating the cause may lead to repeated problems.
Maintenance & Replacement Checklist
During scheduled servicing, inspect the shaft connection for movement, wear & damaged fasteners.
Confirm that the replacement bush matches the original series, bore & keyway requirements.
For broader maintenance needs, explore Drive Accessories & Maintenance.
Record the full product designation for future servicing.
Taper Lock Bushes & Hubs FAQs
What Is a Taper Lock Bush Used For?
A taper lock bush mounts a compatible pulley, sprocket or hub onto a shaft. It uses matching tapered surfaces & a specified fastening arrangement.
What Does 1610 Mean on a Taper Lock Bush?
1610 identifies a particular taper lock bush series. The finished shaft bore is a separate specification.
What Does 1610-40 Mean?
In the documented Finer product, 1610 identifies the series & 40 indicates the 40 mm bore. The product also specifies a 12 × 8 mm keyway.
Are Taper Lock Bushes Interchangeable Between Brands?
Some products may share standardised dimensions, but interchangeability should not be assumed. Confirm the complete series, dimensions, fasteners & manufacturer requirements.
Do Taper Lock Bushes Need a Shaft Key?
Many taper lock mounting arrangements use a key. The correct connection depends on the bush, shaft & hub design.
Can I Change the Bore Size Without Changing the Bush Series?
A particular series may be offered in multiple finished bore sizes. The selected bush must match the shaft & remain compatible with the mating hub.
How Do I Remove a Taper Lock Bush?
Many designs use specified removal screw positions to release the tapered connection. Follow the manufacturer's procedure to avoid damaging the shaft, bush or hub.
Why Does a Taper Lock Bush Come Loose?
