Bill of Materials Data

Manufacturer RULAND
Description Disc Coupling, Single Disc Clamp Style, Bores 0.250"x0.125", OD 0.590", L 0.719", 2024 or 7075 Aluminum Hubs, 302 Stainless Steel Disc Springs, COO USA
Part number DCS10-4-2-A
Note 1 Stainless steel hubs are available upon request.
Note 2 Torque ratings are at maximum misalignment.
Note 3 Performance ratings are for guidance only. The user must determine suitability for a particular application.
Note 4 Torque 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.
Note 5 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. Consult tech support for assistance.
