	H Series

Stainless Steel

Features High torque capacity High fatigue resistance Corrosion resistant steel (CRES) The H Series coupling/coupler is ideal when high strength, excellent fatigue resistance and high torsional stiffness is called for in your application. The H Series' premium performance capability is designed for applications requiring a heavy-duty coupling, such as drive systems, small pumps and gear boxes.

Features of the H Series Technical Data & 3D Models No Maintenance Shaft sizes from 3/32 to 3/4 An array of options, in a variety of diameter sizes, allows you to tailor the H Series to your specific applications. H Series options include set screw or integral clamp attachments and inch or metric bores.

How to Order Coupling part numbers consist of four sections. To determine the correct numbers/letters for each section of a specific coupling part number, please refer to the instructions on the right.   Example ** Refer to "Standard Bore Diameters" section in chart 1. Basic Model Number:      Choose material and attachment method. integral clamp         HCR = Stainless steel, integral clamp     HR =   Stainless steel, set screw 2. Outside Diameter Designator: This three-digit number represents the coupling outside diameter. Based on the Performance Data in the middle of the chart, select the Outside Diameter Designator by moving left to the appropriate diameter. 3. Major Bore Designator: The larger of the two bores, its diameter is expressed in either 32nds of an inch (-8 equals 1/4 inch) or in millimeters (6mm). Please review your selection to determine if both bores can be made in the size coupling you have selected in 2. It is important that the larger bore be stated first. 4. Minor Bore Designator: The smaller of the two bores is expressed the same as the Major Bore designator.  Either bore can be inch or mm.
