Note: Limited end float couplings can be special ordered for end float +/- increase or decrease and accommodate greater angular misalignment. They can be combined with axial slide couplings to be used as stops for +/- travel. Consult factory for special design needs.

T-Series standard couplings are designed to allow free axial movement of driver and driven shafts. Limited end float couplings should be specified for all applications requiring limited or controlled axial end float such as sleeve/babbit bearing motors, fans, blowers, etc. Consult factory for questionable applications. Limited end float flex hub and inserts are used with standard ring hubs and drive rings. Available for use with spacer and non-spacer couplings.
