Fadal Motor Couplers: Types, Uses and Compatibility

Fadal motor couplers connect a motor to mechanical components within a CNC machine. They transfer rotational motion and power from the motor, helping the machine perform controlled and precise movements.

Different Fadal CNC applications require different coupler styles, bore dimensions, and motor compatibility. The Fadal motor couplers available through ITSCNC include original heavy-duty couplers, Oldham-style couplers, a two-lobe coupler insert, and a Renbrandt coupler for a DC motor and resolver.

What Do Fadal Motor Couplers Do?

According to the ITSCNC coupler category, motor couplers perform several important functions in CNC machines.

Power Transmission

The coupler transfers rotational power generated by the motor to the connected mechanical component. This power helps operate and control moving parts within the CNC machine.

Misalignment Compensation

Certain motor couplers can compensate for small amounts of misalignment between connected components. This helps maintain smooth operation when the shafts are not perfectly aligned.

Vibration Dampening

Motor couplers can absorb and reduce vibrations created during motor operation. Limiting vibration helps support the accuracy and quality expected during machining.

Component Protection

Couplers can help protect the motor and connected machine components from sudden movements and shock loads.

Original Heavy-Duty Fadal Motor Couplers

MTR-0154-ITS: 5/8" × 5/8" Bore

The MTR-0154-ITS is an original heavy-duty-style motor coupler kit with a 5/8" × 5/8" bore.

ITSCNC describes this product as a steel coupler designed for Fadal CNC machines. It connects the motor shaft to another mechanical component and transfers torque and rotational movement while accommodating slight misalignment.

Its heavy-duty construction is intended to support demanding CNC operations while helping reduce vibration and wear.

MTR-0155-ITS: 5/8" × 7/8" Bore

The MTR-0155-ITS is another original heavy-duty-style option. It has a 5/8" × 7/8" bore configuration and is designed as a replacement component for Fadal CNC machines.

According to its product page, this coupler connects the motor to the machine’s drive components and transfers power and torque. Its bore dimensions are important for establishing the correct connection between the motor and drive system.

Customers should contact ITSCNC to confirm whether this configuration is appropriate for their specific Fadal CNC machine.

Oldham-Style Fadal Motor Couplers

MTR-0154A: 5/8" × 5/8" Bore

The MTR-0154A is an Oldham-style coupler with a 5/8" × 5/8" bore.

This coupler creates a connection between the motor and the driven component while transferring torque through the machine. Its Oldham-style design allows it to accommodate small amounts of angular, parallel, and axial misalignment.

The MTR-0154A product page identifies it for use with:

• MTR-0002 motors

• GM4050 motors

Compatibility should still be confirmed before purchasing the part.

MTR-0155A: 5/8" × 7/8" Bore

The MTR-0155A is an Oldham-style motor coupler kit with a 5/8" × 7/8" bore.

It transfers torque between the motor and components such as ballscrews or gearboxes. Its flexible connection compensates for small amounts of misalignment while helping reduce vibration and wear.

The MTR-0155A is designed for use with:

• MTR-0010 motors

• MTR-0141 motors

• MTR-0146 motors

ITSCNC states that this coupler is not intended for other motor models because its bore dimensions and design are optimized for the motors listed above.

ENC-0023 Renbrandt Coupler for DC Motor and Resolver

The ENC-0023 is a Renbrandt coupler designed for DC motors and resolvers in Fadal CNC machines.

Its primary application is connecting the MTR-0003 DC motor to the resolver. It transfers torque and rotational movement between these components, supporting accurate positioning and movement within the CNC machine.

The ENC-0023 is specifically compatible with the MTR-0003 DC motor. Customers who are unsure about compatibility can contact ITSCNC for assistance.

MTR-0071 Two-Lobe Coupler Insert

The MTR-0071 is a Fadal motor disk coupler insert with a two-lobe design.

This insert supports power transmission within the CNC motor system by creating a secure connection between the motor and connected machine components. Its design supports effective torque transfer while helping prevent slippage and misalignment.

The MTR-0071 is intended for certain Fadal CNC machine models. The specific machine application should be confirmed with ITSCNC before ordering.

How to Select a Fadal Motor Coupler

The ITSCNC product range shows that three details are especially important when comparing coupler options.

Coupler Style

First, determine whether the application requires:

• An original heavy-duty coupler

• An Oldham-style coupler

• A two-lobe disk insert

• A Renbrandt motor and resolver coupler

Bore Dimensions

The available motor coupler kits include:

• 5/8" × 5/8" bore

• 5/8" × 7/8" bore

The required dimensions should match the intended motor and drive components.

Motor Compatibility
