Getting More Out Of Your Standard Coupling. Did you know that merely by reversing the hubs on your Lovejoy/Sier-Bath gear coupling you are able to satisfy shaft gaps up to three inches – at no additional cost! Simply reverse one hub or both hubs to obtain what is needed. Stock Spacers are available for greater shaft gaps. For more details, refer to the gear coupling section of Lovejoy’s Full Line Catalog (# 685144-50174).
