The FHP23K Split Taper Bushing is a 1/2" bore steel bushing with a 5/8" outside diameter and a split body, used to mount FHP drive components — sheaves, pulleys and sprockets — onto a 1/2" shaft without machining the bore or using a keyway on the shaft. The split body compresses when the mounting screws are tightened, so the bushing grips the shaft through friction rather than through a key. Installation and removal are done without pulling the driven component off the shaft. This is the standard mounting interface on FHP sheaves, FHP pulleys and light-duty sprockets used in conveying systems, pumps and power transmission equipment.
Raydafon supplies the FHP23K Split Taper Bushing as an ISO 9001 certified manufacturer from the Ningbo factory. Stock quantities ship in 7 to 15 days. OEM replacement is supported when the original part number or a dimensioned drawing is provided.
An FHP23K Split Taper Bushing is a mechanical mounting component used to fix a pulley, sheave or sprocket onto a 1/2" diameter shaft. The bushing has a split body with a tapered outside surface and a matching tapered bore inside the driven component. When the mounting screws are tightened, the split body closes and presses against the shaft. The friction between the compressed bushing and the shaft transmits the torque from the driven component to the shaft — without needing a keyway cut into the shaft itself. This is what makes the FHP23K split taper bushing a common choice for FHP drive systems that need fast installation and easy removal.
The FHP23K is one of the smaller sizes in the FHP split taper bushing family. It is used when the shaft diameter is 1/2" and the driven component is a light-duty FHP sheave, pulley or sprocket. For larger bore sizes, Raydafon produces the full FHP taper bushing range in the same split-body design.
The table below lists the full dimensional and material specification of the FHP23K Split Taper Bushing. All values are confirmed against the original FHP drive specification. For OEM replacement, Raydafon matches the taper angle, keyway position and overall length to the original unit before shipping.

A split taper bushing offers four practical advantages over a solid (non-split) bushing or a keyed bore in the driven component. These advantages are the reason the FHP23K Split Taper Bushing is the standard mounting interface on light-duty FHP drive components.
The split-body taper locks to the shaft by friction. No keyway has to be cut into the shaft, which means the FHP23K can be installed on any standard 1/2" shaft without additional machining.
Loosening the mounting screws releases the split, so the FHP23K comes off the shaft without removing the sheave, pulley or sprocket from the assembly first. This saves time during maintenance or replacement.
The split-body design compresses evenly around the shaft circumference, so the friction load is distributed rather than concentrated at one keyway edge. This reduces shaft damage on repeated install and removal.
The taper multiplies the tightening force of the mounting screws into radial clamping pressure on the shaft, so a small bushing like the FHP23K can transmit meaningful torque without a large housing envelope.
The FHP23K Split Taper Bushing is used anywhere a light-duty FHP sheave, pulley or sprocket needs to be mounted onto a 1/2" shaft. The four application areas below are the most common in OEM and replacement work.
Light-duty belt and chain conveyors where FHP sheaves and sprockets are mounted on 1/2" shafts. The split body allows fast replacement of worn drive components without dismantling the conveyor frame.
Small pumps, circulation pumps and pump skids where FHP pulleys are mounted on 1/2" pump shafts. The friction grip avoids a shaft keyway, which simplifies pump shaft replacement.
Small gear reducers, blowers, fans and similar equipment where an FHP sheave or pulley is mounted on a 1/2" input or output shaft.
Direct replacement of an existing FHP23K Split Taper Bushing where the original unit is worn, cracked or lost. Raydafon matches the taper angle, keyway and length to the original.
To confirm the correct FHP23K Split Taper Bushing and issue a quotation, Raydafon needs the five items below. For a straight replacement of an existing unit, the original part number alone is usually enough.
Send the five items below and Raydafon will confirm the specification, stock availability and lead time within one working day.
The FHP23K Split Taper Bushing is used to mount FHP sheaves, pulleys and sprockets onto a 1/2" shaft. It uses a split-body taper to grip the shaft by friction, so no shaft keyway is needed. It is common on light-duty conveying systems, pumps and power transmission equipment.
The FHP23K Split Taper Bushing has a 1/2" inside diameter, a 5/8" outside diameter and a 1-1/8" length. Bore type is finished with keyway, keyway size 3/16" × 5/32" or 1/8" × 1/16" depending on the driven component. Material is steel.
No. The FHP23K Split Taper Bushing locks onto the shaft by friction from the split-body taper. The bushing itself has a keyway on the bore for the driven component to key onto, but the shaft itself does not need a keyway cut into it.
Yes. Send the original part number, nameplate photo or a dimensioned drawing and Raydafon will confirm whether the taper angle, keyway, bore and length match. Where the original is obsolete, a functionally equivalent FHP Split Taper Bushing can be supplied against the same mounting configuration.
Stock quantities of the FHP23K ship in 7 to 15 days. Custom configurations and larger quantities are confirmed with the quotation. Raydafon supplies OEM, project and factory-direct quantities from the Ningbo factory.
Raydafon produces the full FHP Split Taper Bushing range, from the small FHP23K up to the larger FHP sizes for higher-bore shafts. Custom sizes can be produced to a dimensioned drawing when the required size is not in the standard range.
Every FHP23K Split Taper Bushing shipment includes an outline drawing, a dimensional inspection report and a material certificate on request. Third-party inspection can be arranged when the project specification calls for it.
Whether you are replacing a worn FHP23K on a light-duty conveyor, specifying an FHP sheave mounting for a new pump skid, or building an OEM kit that requires split taper bushings, Raydafon can quote the FHP23K or a custom equivalent to your bore, keyway and torque requirements. OEM and project quantities supplied directly from the Ningbo factory.
