MOTOX C48-LA80M4 Helical Worm Gearmotor
The iconic MOTOX gearmotor series was originally created and engineered by FLENDER. Following Siemens' acquisition of Flender, MOTOX was integrated into Siemens' drive portfolio under the 2KJ catalog line (2KJ1602 for C48). Subsequently, Siemens carved out its heavy-duty motors and gearmotors business under the INNOMOTICS brand. Today, MOTOX products have transitioned back to the original manufacturing plants and authentic OEM supplier channels, ensuring 100% exact design continuity, mechanical interchangeability, and original quality standards.
The MOTOX C48-LA80M4 is a 2-stage right-angle helical worm gearmotor combining a high-efficiency primary helical gearing stage with a heavy-duty worm gear output set. Cataloged under Siemens 2KJ order code 2KJ1602, the C48 size delivers nominal output torques up to 260 Nm and is paired with 0.55 kW LA80M4 motors. Designed for quiet running, space-saving installation, and elevated mechanical efficiency over standard pure worm reducers, MOTOX C series gearmotors are available in versatile configurations (foot C48, hollow shaft CA48, flange CF48/CAF48, shrink disc CAD48, and housing flange CZ48) ideal for conveyor lines, stage machinery, food packaging, and water treatment drives.
