Boreable

One commercially available form of this type of bearing has a boreable 0.010 in.-thick lining of acetal copolymer, while another form has a thinner, 0.004 in.-thick, lining of the homopolymer.

Some factory workers are intolerably bored by monotonous tasks; others prefer them. The boreable, on the other hand, develop on occasion the most furious initiative in their efforts to escape boredom.
