Example of designation of the SPJ coupling with the nominal torque of Mn=3150 Nm, hub hole diameters of d1=50 mm, d2=60 mm, hub hole lengths of l1=80 mm, l2=140 mm, size of 003:
3150-50/80-60/140-003 SPJ Single-sided gear coupling
Single-sided gear couplings are used in pairs with a spacer shaft.
In cases where journal misalignment is excluded, a single SPJ coupling may be used.
Screw-tightened covers are used from sizes 005 to 009.
Sizes 004 and smaller are manufactured with non-removable covers.
