2	Slow Roll	1×	Chilled cast-iron roll at about 0.4 times the fast-roll speed; the speed difference shears the grain open.
3	Roll Bearing 2 parts	4×	Two per roll
4	Bearing Block	4×	Cast housing that holds a roll bearing; the slow-roll blocks slide for gap adjustment.
5	Oil Seal	4×	Spring-loaded rotary lip seal that keeps lubricant inside a housing and dirt out where a shaft passes through, sized to DIN 3760.
