The Spider is in the center of the two hubs and is essential to making a complete coupling. With a flexible spider it allows a small misalignment of the hubs to not explode the equipment. All the spiders are suitable for power transmission in hazardous areas. Spiders are designed specifically to make the coupling operable even with a slight miscalculation between two pieces of equipment.

Our KTR couplings are "LTSOH" (Limited to Stock on Hand) and will no longer be available after the current stock has been depleted.
