Product Name Notes
Slit Beam™ Couplings Misalignment motor shaft couplers are designed to absorb the misalignment between the shafts. Ondrives offers various motor gear coupling types to solve every type of misalignment problem and to protect...
Oldham Sliding Disc Couplings Oldham couplers transmit rotation through central wear discs that slide over tenons on their hubs. Our standard model sliding disc couplings are manufactured with injection molded, self-lubricating Acetyl wear discs...
Bellows Shaft Couplings Ondrives.US Bellows couplings comprise two end hubs with set screws or an integral clamp to fasten to a shaft. The flex member of the coupling is hydro formed from tubing...
Shaft Bore Reducers (Adaptors) Ondrives.US Bore Reducers, sometimes referred to as bore reducer sleeves or bushings, are simple adaptors that slip into the bore hole of a rotating component and reduce the bore diameter...
Double Loop, Crazy Eight, K Coupling Ondrives.US Double Loop Couplings are made with DuPont’s Hytrel™ material, substantially improving the performance characteristics over competitors Double Loop Couplings, also known as a "Crazy Eight Coupling" or “K Coupling”.
Lateral Offset Shaft Coupling Ondrives.US is a shaft coupling supplier that designs and manufactures some of the industry’s best-performing, most reliable shaft couplings. Our Universal-Lateral and Cross Joint offset couplings are unique, light-duty devices...
Step-Beam™ Couplings Ondrives.US patented Step-Beam™ couplings are zero-backlash, shaft to shaft misalignment couplings. We created the Step-Beam™ coupling to solve some of the short falls of other beam shaft coupling types. Ondrives.US...
Membrane (Disc) Shaft Coupling Ondrives.US’ durable membrane couplings, also known as disc couplings or wafer spring couplings, utilize spring steel membranes as their pivotal members. Torque is resolved to simple tensile stresses in opposing...
Flexible Insert Couplings Rigid shaft connector couplings accomplish this goal but they do not deal with angular and radial misalignment or axial movement that may exist between the shafts. When rigid shaft couplings...
Spiral Beam Couplings Spiral beam couplings are highly flexible precision machined shaft to shaft couplers that compensate for Axial, Angular and Radial (Parallel) misalignment between shafts. Spiral couplings are some of the most...
Servo-Beam™ Couplings The patented Servo-Beam™ motor couplings are the best replacement for expensive and delicate bellows couplings. The Servo-Beam™ coupling is a true servo coupling exhibiting torsional rigidity, zero backlash, high RPM...
Jaw Couplings (Spider) Typical Jaw type couplings are 3 piece units comprised of two metal hubs encapsulating an elastomeric element. A Jaw coupler allows high torque transmittal with little or no backlash regardless...
Servo - High Gain Couplings Vibration Absorption Coupling, Aluminum Hubs, Rubber Core, Clamp Style
