I-TA MACHINERY FM28 Gear Speed Reducer 220/380 VAC Ratio 1:6 shaft diameter 25.4 mm 90VDC Brake

Buy online your I-TA MACHINERY FM28 Gear Speed Reducer from our US e-store Cnc-shopping USA, specialist in CNC machine-tools spare parts.

The FM28 from I-TA MACHINERY is a compact gear speed reducer with an integrated brake, designed for industrial machinery and CNC auxiliary equipment that require controlled speed reduction and reliable load holding. Featuring a 1:6 reduction ratio, a 25.4 mm shaft interface, and a 90 VDC holding brake, it is well suited for conveyors, feeders, indexing mechanisms, and other automated systems.

This gearbox reduces motor speed while increasing available output torque, making it ideal for auxiliary motions on machine tools and industrial automation equipment. The 1:6 ratio provides an effective balance between torque multiplication and output speed, supporting smooth and consistent operation in conveying, positioning, and indexing applications.

The integrated 90 VDC brake ensures positive load holding when the motor is stopped, preventing unwanted movement during machine pauses, tool changes, maintenance operations, or emergency stops. This feature is particularly valuable in applications where position stability and operational safety are essential.

Designed to operate with 220/380 VAC gearmotor assemblies, the FM28 can be easily integrated into standard industrial control systems where the brake coil is powered separately. The 25.4 mm output shaft matches many commonly used industrial couplings and hubs, simplifying installation and reducing maintenance time during replacement projects.

In CNC environments, the FM28 is commonly found on chip conveyors, parts feeders, coolant handling systems, packaging equipment, and light-duty positioning mechanisms where accurate stopping and reliable torque transmission are required. Its robust mechanical design supports continuous-duty operation in demanding production environments.

For maintenance teams, this model is often selected as a direct replacement when an existing gearbox becomes worn or when the brake no longer provides sufficient holding force. Matching the original ratio and shaft dimensions allows for a straightforward replacement with minimal alignment work and reduced machine downtime.

Each unit can be inspected and tested on dedicated mechanical test benches to verify smooth rotation, gearbox condition, brake engagement at 90 VDC, and overall operational performance. The FM28 is a dependable solution for maintenance, retrofit, and spare-parts programs, helping extend the service life of industrial equipment and CNC installations.

Frequently asked questions about FM28:

Does the brake require a dedicated supply?
Yes, the integrated brake coil is 90 VDC. It must be powered from a suitable DC source or rectifier in the control cabinet. Verify the cabinet output before commissioning.

Can I replace a different ratio with this model?
Only if the machine can accept the speed and torque change. The 1:6 ratio defines output speed and available torque, so matching the original ratio is recommended for a true drop-in replacement.

What should I check for mechanical fit?
Confirm the 25.4 mm shaft interface and the mounting pattern against the original unit. Verify coupling size and alignment to avoid premature wear.

Is this suitable for North American plants?
The reducer is mechanical and not tied to mains voltage. It is commonly paired with 220/380 VAC motors, while the brake needs 90 VDC. Ensure your motor rating and cabinet brake supply match these requirements.

Can this be used as a stocked spare for preventive maintenance?
Yes, it is commonly held as a stocked replacement unit so teams can swap it during scheduled stops and keep machine uptime high.
