Quality Products for Mechanical & Fluid Power

an excellence in engineering The comprehensive service for the mechanical power transmission & fluid power industries. ® Gear Couplings Gear couplings have the highest power density, offer more variations, a wider size, torque, and bore capacity than any other coupling type. They are easily modified for shear pin service, floating shaft type, vertical applications, electrical isolation, limited end float, and can have a brake drum or disc added. While some features may be available on other couplings, it is typically easier and cost effective to modify a gear coupling. With all these...

Vertical Floating Shaft Type The upper coupling is a Standard Vertical Type coupling. The lower coupling has a hardened crowned button inserted in the plate of the lower hub and a hardened flat button inserted in the plate of the upper hub. The entire floating assembly rests on these two buttons which carry the weight of the floating assembly thus maintaining the spacing between the two lower hubs allowing for flexibility. The hubs on the floating shaft are flexible and the hubs of the driver and driven shafts are rigid. Brake drum Type Two different designs of brake drum couplings are...

Hercuflex All-Steel Gear Couplings Continuous Sleeve Gear Couplings ® Sliding Hub Type The sleeve is longer than standard and is designed to allow for a predetermined amount of axial travel on one shaft. The short hub is secured to the sleeve by means of a spacer washer and snap ring which prevents travel. This type is also manufactured to allow for travel of both hubs in the sleeve. This coupling is also available with a rigid type short hub. Jordan Type Used on Jordan machines and refiners, this design is similar to the Sliding Hub Type coupling except the long hub is split and secured to...
