Model 3B

Similar to Model 3, except the centre shaft is supported by internal maintenance-free bearing material. This allows for greater equipment separation and high speeds, as well as high angular misalignment, which can be obtained with rubber flexible elements.

One of the many features of the Model 3 is that the centre floating shaft can be radially removed without displacing the coupled machines. Flexible elements may be pre-assembled to the centre segment and then finally assembled to the hubs fast and with little hardware.
