Inch Bore Shaft Locking Bushes For Industrial Power Transmission

Reliable power transmission starts with choosing the correct shaft locking components. Finer Imperial Taper Lock Bushes provide a standardised solution for mounting pulleys, sprockets, couplings & other rotating equipment onto imperial (inch) shafts used throughout manufacturing, agriculture, mining, food processing & material handling industries.

Designed to suit industry-standard taper lock hub series, these bushes simplify installation, improve component interchangeability & help reduce maintenance downtime. Whether you're replacing a worn bush or specifying components for a new machine build, selecting the correct taper lock bush ensures compatibility between the shaft, keyway & hub.

What Are Imperial Taper Lock Bushes?

Imperial taper lock bushes are split tapered shaft locking devices that securely mount pulleys, sprockets, couplings & other rotating components onto inch-sized shafts.

Rather than machining every hub to suit an individual shaft diameter, taper lock systems allow a compatible hub to accept different finished bore sizes simply by changing the bush.

Each bush typically includes:

• Precision tapered outer surface

• Finished imperial bore

• Machined keyway (where applicable)

• Mounting & removal screw holes

As the screws are tightened, the bush seats into the matching hub taper, creating a secure mechanical connection between the shaft & driven component.

For buyers selecting complete drive components, you'll also find compatible Keys & Keyways & Shaft Collars & Locking Bushings within our drive maintenance range.

• Roller conveyors

• Packaging equipment

• Materials handling systems

Agricultural Machinery

• Grain augers

• Feed systems

• Harvesting equipment

• Irrigation drives

Industrial Machinery

• Pumps

• Compressors

• Mixers

Choosing The Correct Imperial Taper Lock Bush

Selecting the correct bush starts with identifying both the hub series & shaft size.

Step 1 — Identify the Bush Series

Common taper lock series include:

• 1008

• 1108

• 1210

• 1610

• 2012

• 2517

• 3020

• 3030

• 3535

• 4040

• 4545

• 5050

Always match the series specified by the pulley, sprocket or coupling manufacturer.

Step 2 — Confirm the Finished Bore

Ensure the finished bore matches your imperial shaft diameter.

Never assume a metric & imperial shaft are interchangeable.

Step 3 — Check Keyway Compatibility

Verify:

• Shaft size

• Key dimensions

• Hub specifications

• Finished bore

Matching all components ensures proper installation.

Step 4 — Inspect Associated Drive Components

When replacing a taper lock bush, inspect related components including:

• Sprockets – Simplex, Duplex, Taper Lock, Idler

• Flexible Couplings (Jaw, Grid, Disc, Gear, Elastomeric)

• Pulleys, Blocks & Sheaves

• Alignment Tools (Laser, Dial, Manual)

Inspecting the complete drive system during maintenance can help identify wear before it causes unplanned downtime.

Imperial vs Metric Taper Lock Bushes

Although they perform the same function, imperial & metric taper lock bushes are manufactured for different shaft measurement systems.

Always confirm the shaft measurement before ordering.

Expert Tips

Routine inspections often reveal wear elsewhere in the drive assembly before the taper lock bush itself requires replacement.

During scheduled maintenance:

• Inspect shaft wear

• Check keyway condition

• Clean hub tapers

• Replace damaged mounting screws

• Confirm shaft alignment

If you're servicing multiple rotating assets, monitoring vibration can help identify misalignment & premature wear before major failures occur. Consider using Vibration & Condition Monitoring Tools as part of your preventative maintenance program.
