型号举例/Example: GLG - □□ × □□ - □□ × □□

Series Diameter Length d1Bore d2Bore

Note: If an additional keyway is required, it can be customized in a non-standard form. Please add K after the model shaft diameter size. For example, GSN-32 × 29-8K × 9K means that both inner holes have keyway openings.

Note: The inner diameters of the inner holes at both ends of the coupling can be freely combined from small to large. The inner holes are machined with H7 standard tolerance, and the inner diameter dimensions marked in the table are for reference only. Please contact us for detailed parameters of the aperture you require.

Product model	Torque (N.m)	Allowable eccentricity (mm)	Allowable deviation angle (∠°)	Allowable axial deviation (mm)	Allowable rotational speed (RPM)	Static torsional stiffness (N.m/rad)	Moment of inertia (N.m)	Coupling weight (g)
GSN-19×20	1	0.02	1	±0.10	15000	600	2.9×10⁻⁷	13
GSN-25×24	2	0.02	1	±0.20	15000	1300	1.1×10⁻⁶	25
GSN-32×29	2.5	0.02	1	±0.30	10000	2500	4.0×10⁻⁶	57
GSN-40×33	3.5	0.02	1	±0.30	10000	4600	9.8×10⁻⁶	86
GSN-50×42	9	0.02	1	±0.30	10000	6000	1.6×10⁻⁵	130

Note: The above inertia moment and various technical parameters are measured from the standard of large aperture to the value of large fixed torque, which is related to the durability of the coupling itself. The larger the outer diameter, the greater the force, and the smaller the outer diameter, the higher the allowable speed.
