The document provides specifications for a coupling model SWF, including: 1. The model ranges from SWF225 to SWF620 with gyration diameters from 225mm to 620mm. 2. Parameters such as nominal angular force, fatigue angular force, and axis angle are provided for each model. 3. Dimensions, standard dilation, minimum length, weight and other information is included in two tables for basic types. 4. Notes specify that flange diameters can be increased and couplings can be customized to meet special requirements. 5. The document is from Timothy Holding Co. and includes links to their website.

Note (1)The squares in models stand for types of couplings, i.e.A, B, C, D, or E Blank squares for basic types.
(2)Flange Dia. of both ends of standard couplings are same as the gyration Dia. flange Dia. may be increased by 1-2grade or willfully on customers’
requests.
(2)Couplings with excessive flex may be manufactured on customers’ requests.
