Material SpecificationHubs: 2024-T351 Aluminum Bar, Disc Springs: Type 302 Stainless Steel
Maximum Speed10,000 RPM
Note 1Stainless steel hubs are available upon request.
Note 2Torque ratings are at maximum misalignment.
Note 3Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 4Torque ratings for the couplings are based on the physical limitations/failure point of the disc springs. Under normal/typical conditions the hubs are capable of holding up to the rated torque of the disc springs. In some cases, especially when the smallest standard bores are used or where shafts are undersized, slippage on the shaft is possible below the rated torque of the disc springs. Keyways are available to provide additional torque capacity in the shaft/hub connection when required. Please consult technical support for more assistance.
