LOVEJOY L Type Hubs Without Keyway, Inch Bores
Lovejoy keyless L-type couplings are assembled using two of these hubs and an open-centre spider. They are used to accommodate parallel & angular misalignments between two rotating shafts. The keyless design facilitates easy adjustability & releasable shrink-fit; and eliminates backlash errors ...(fretting, corroding & wallowing).Read more
