Motion Control Couplings with Inch to Metric Bores




asndsa

Motion control couplings are now available from stock with inch to metric bores in a variety of styles.

Motion systems often utilize a metric servo or stepper motor driving an inch ball screw, lead screw, or encoder. Coupling selection is a difficult task which becomes more challenging when inch to metric bore combinations are needed. Ruland now offers motion control couplings with inch to metric bores from stock to allow engineers to select the style that best fits their application.

Ruland now offers motion control couplings with inch to metric bore combinations in a wide variety of sizes, styles, and materials. Performance factors such as torque, RPM, shaft misalignment, and space requirements should be considered when selecting a servo coupling. Matching application parameters to a motion control coupling can be challenging and is critical to system performance..

Beam Couplings: Have excellent all-around performance characteristics, large misalignment capabilities, and are a good starting point. Relatively low torque and torsional stiffness when compared to other servo couplings. Bore sizes ranging from 1/8” to 3/4” and 3mm to 20mm.

Bellows Couplings: Highest degree of torsional stiffness for applications that require accuracy and repeatability. Suitable for speeds in excess of 10,000 RPM. No provision for impact loads and limited misalignment capabilities. Bore sizes ranging from 1/8” to 1” and 3mm to 25mm.

Disc Couplings: Suitable for delicate equipment requiring highly precise positioning. Discs allow for misalignment while offering high torsional rigidity. Some styles are not suitable for complex or parallel misalignment. Bore sizes ranging from 1/8” to 1-1/4” and 3mm to 32mm.

Jaw Couplings: Dampens impulse loads and is electrically isolating. Multiple spider materials for a range of dampening and torque capacity. Low misalignment capabilities due to high bearing loads when used improperly. Bore sizes ranging from 1/8” to 1-1/4” and 3mm to 32mm.

Oldham Couplings: Well suited for large amounts of parallel misalignment. Offer light bearing loads, low inertia, electrical isolation, and easily interchangeable hubs. Not suitable for push-pull applications or unsupported shafts. Bore sizes ranging from 1/8” to 1-1/4” and 3mm to 32mm.
