Example of designation of the SPJ-SBH coupling with the nominal torque of Mn=1300 Nm, brake drum diameter of DH=200 mm, distance of the brake drum symmetry axis from the hub origin of LH=87, hub holes diameters of d1=40 mm, d2=45 mm, hub holes lengths of l1=62 mm, l2=82 mm, size of 45:
1300-200-87-40/62-45/82-45 SPJ-SBH Brake drum gear coupling
Single-sided gear couplings are used in pairs with a spacer shaft.
In cases where journal misalignment is excluded, a single SPJ (SPJ-SBH) coupling may be used.
