A correct center distance must be consistent with the tooth geometry of both members. A pair with the same nominal module can still be incompatible if other geometry differs.<\/p>\n

If only samples are available, identify which surfaces are bearing datums. Wear on an old wheel or shaft can make direct measurement misleading.<\/p>\n
