Motor shaft extender Simagic E-20CM — 20 cm extension for motor shaft

Simagic E-20CM motor shaft extender provides a 20 cm extension to compatible motor shafts, increasing reach for mounting steering wheels, adapters or custom rig components. The extender is intended to maintain alignment and transmit rotational motion between the motor and attached hardware, enabling easier installation and greater flexibility in sim racing setups and DIY rig modifications.

Advantages

The shaft extender offers an extended length of 20 cm while preserving rotational coupling and alignment between motor and accessory. Its design minimizes additional play and supports stable torque transmission, reducing the need to reposition the motor or redesign mounting points. The extender enables straightforward attachment of a variety of wheel hubs and adapters without altering the original motor housing.

Suitable for

• Sim racing rigs requiring additional shaft reach for wheel or adapter mounting
• DIY cockpit modifications where motor position cannot be changed
• Testing and development of custom wheel hubs and extensions
• Workshops that need temporary or permanent extension of motor drive shafts

Key specifications

• Extension length: 20 cm
• Function: transmits rotational motion and extends motor shaft reach
• Compatibility: for use with compatible Simagic motor shafts and matching couplings
• Application: designed for sim racing, wheel mounting and custom rig components

How to use

Align the extender with the motor shaft and the intended accessory, ensuring mating surfaces and keyways (if present) match. Secure the extender to the motor shaft using the appropriate set screws, clamps or coupling hardware supplied or recommended for the motor model. After installation, verify axial alignment and torque transmission by gently rotating the assembly and checking for wobble or looseness. Tighten all fasteners to the manufacturer-recommended torque and confirm secure attachment before normal operation.

Recommendations

Use the shaft extender only with compatible motor shafts and couplings. Inspect connections periodically for tightness and wear, and avoid excessive bending loads or lateral forces that could increase play or stress on the motor bearing. When possible, support longer assemblies to reduce strain on the motor shaft and maintain consistent performance in sim racing applications.
