Rigid Couplings

    Shaft Couplings serve as components to time, join, or align shafts at lower speeds and torque, especially when zero backlash is desired. Climax Metal Products Company provides a broad assortment of Shaft Couplings to suit many customer applications. Climax Rigid Couplings fit imperial shaft sizes from ¼” to 2 ¼” and metric shaft sizes from 6mm to 50mm. Rigid Couplings are made from mild steel with a black oxide finish or type 303 stainless steel. A limited selection of Shaft Couplings is offered using aluminum material. Couplings are manufactured both with and without keyways. Step-Bore Couplings are also available to attach two shafts of differing sizes.

    Set Screw Rigid Couplings are the most commonly used and economical Shaft Couplings. The holding power of a Set Screw Coupling is provided by the impingement of the screws into the shaft. If additional torque capacity is required, Climax provides Set Screw Shaft Couplings with a second set of screws at 90°.

    One-Piece Split Couplings are designed to handle applications that require a greater torque capacity than Set Screw Shaft Couplings without marring the shaft. Recessed screw styles of One-Piece Clamp Couplings are available to provide safety with an outside surface free of major projections.

    Two-piece Clamping Couplings are designed to handle applications that require a greater torque capacity than Set Screw Rigid Couplings and One-Piece Split Couplings without marring the shaft. Because the two halves of Two-Piece Split Couplings can separate completely, major disassembly of the other shaft components is not required for installation. Recessed screw styles of Two-Piece Clamp Couplings are available to provide safety with an outside surface free of major projections.

    Re-Machinable Couplings are Two-Piece Clamp Couplings with an undersized bore allowing the customer the necessary clearance to re-machine the bore without damaging the existing clamp screws. The pilot bore can be safely enlarged to the nominal bore size reflected in the part number nomenclature. These Split Couplings allow for customization and limit downtime.

    Shaft Adapters allow for repairing, altering, extending, increasing or decreasing the current shaft. Step-Down Adapters provide a step from a larger current shaft to a smaller one. Step-Up Adapters couple a smaller shaft and extend to a larger one. They are easily installed and compatible with all standard round shafts.
