1．From SM-20C to SM-200C, a cut can be easily made up to the central bolt through-hole with a cutter or the like.
Therefore, even existing machines can be easily inserted from the side.
2．If the machine feet do not touch the entire surface of Anti-vibration rubber, be sure to use the optional plate.
3．If earthquake-resistant measures are required, secure the strength of the mounting members and foundation bolts.
4．Leave a gap between the nut and the bush to prevent vibration from propagating to the foundation bolt.
