2021 Good Quality Spline Shaft Coupling - GS Claming Couplings, Type 1a/1a in AL/Steel – GOODLUCK

Because these Type B sprockets are manufactured in quantity, they are more economical to purchase than the re-machining of stock-bore sprockets, with re-boring, and installing the keyway and setscrews. Finished Bore sprockets are available for Standard “B” Type where the hub protrudes on one side.

GS couplings are deigned to transmit torque between drive and driven components via curved jaw hubs and elastomeric elements commonly known as spiders. The combination between these components provides dampening and accommodation for misalignments. This product is available in a variety of metals, elastomers and mounting configurations to meet your specific needs. Ordering Guide: There are three individual part numbers you will need for a complete coupling (i.e., 2 Hubs and 1 Spider). Please choose the hub sizes that match the criteria for your application.
