SEISA SSM180-176754 Gear Coupling

SEISA GC-SSM180, commonly listed as SEISA SSM180, is a gear-type shaft coupling that transmits torque between connected shafts with a compact, robust gear-set construction. Manufactured from carbon steel (equivalent to S45C), it delivers up to 4,730 N·m of torque and supports speeds up to 4,000 rpm, making it suitable for demanding industrial drives. The GC-SSM180 accepts shaft diameters from 32 to 75 mm and measures an overall length of 190 mm with an outer diameter of 180 mm. Key dimensions include dimension A 180 mm and dimension B 105 mm, with additional geometry that influences mounting and alignment. The unit’s axial movement range is -0.5 to +3.0 mm, and it allows an eccentricity of about 1.5 mm, while the weight is approximately 0.5 kg. As part of SEISA’s GC series, the SSM180 variant corresponds to a size 180 gear coupling commonly catalogued across distributors. This model is designed for installation in systems where rigid shaft alignment is present but precision, compact form, and capable torque transmission are required. When selecting a gear coupling, confirm that the shaft bore, torque rating, and maximum operating speed align with your equipment’s specifications to ensure reliable performance.
