Product Overview
The FA107 22kW Gearmotor is engineered for the "Heavy-Duty" bracket of industrial automation. While smaller units prioritize light conveyor tasks, the FA107 is built to handle massive startup loads and continuous high-torque output. The parallel shaft design ensures that the motor remains aligned alongside the machinery, reducing the total length of the drive package.
By utilizing the hollow shaft output, the FA107 eliminates the need for expensive and maintenance-heavy flexible couplings. It slides directly onto the driven shaft of your machine, secured by either a keyway or a shrink-disc, ensuring zero-slip power transmission. This unit is frequently paired with SEW's IE3 or IE4 motor ranges to maximize energy efficiency in energy-intensive 24/7 operations.

FA107 Unique Performance Features
- Massive Radial Load Absorption: The FA107 is equipped with an reinforced output bearing arrangement. This allows the unit to survive significant overhung loads that would typically cause shaft deflection in lighter gearboxes.
- Precision-Ground Gear Flanks: The helical gear sets within the FA107 are ground with a specific "crowned" profile. This micro-correction ensures that even under the maximum 22kW load, the gear contact remains centered, preventing edge-wear and premature failure.
- Integrated Heat Dissipation Fins: The housing casting of the 107 series includes high-surface-area ribbing. This design acts as a natural heat exchanger, allowing the gearbox to maintain thermal equilibrium without the need for external cooling fans in most S1 continuous duty applications.
Installation Flexibility & Shaft Mounting
The FA107 shines in its ability to adapt to complex mechanical interfaces.
- The "Flat" Advantage: Unlike right-angle units that stick out into walkways, the FA107 lies flat against the machine. This is critical for large-scale bucket elevators and heavy-duty mixers where aisle space is a safety priority.
- Torque Arm Integration: Every FA107 housing includes pre-machined mounting points for a rubber-buffered torque arm. This accessory is essential for shaft-mounted units, as it absorbs the reaction torque during motor startup, protecting your machine's drive shaft from shock-loading.

FAQ
Q: Can the FA107 handle a 22kW motor in a vertical mounting position?
A: Yes. However, for vertical mounting (M4 position), we recommend the use of a "drywell" seal or specialized oil expansion chambers to ensure the top bearings are lubricated without risking leakage.
Q: Is the shrink disc option better than a keyed shaft for a 22kW load?
A: For high-power applications like 22kW, a shrink disc (friction connection) is often superior. It provides a backlash-free connection and eliminates the risk of "fretting corrosion," making it much easier to remove the gearbox for maintenance after years of use.
Q: Does the unit come pre-filled with oil?
A: Standard units are filled with a specific amount of oil based on the mounting position (M1-M6) ordered. Always verify the oil level via the sight glass before commissioning to ensure optimal cooling and lubrication.
