The external gear ring and internal gear are usually made of high-strength alloy steel, with the teeth carburized and quenched to raise surface hardness and fatigue resistance. Sleeves and flanges use high-strength materials to carry heavy torque, while the seals are typically oil-resistant rubber that prevents grease leakage and keeps contaminants out of the meshing zone.

Drum gear couplings play a key role in mechanical drive systems; the GICL type is chosen across many industries for its high load capacity and good compensation performance, and is a common component on OEM machines.

For a sound selection, combine the speed, torque class and space constraints of the installation, and verify the choice against sample data and compensation curves before ordering.

Overall, the right size chosen against torque, speed and misalignment, kept well lubricated and sealed, will deliver its rated capacity and a long working life.
