LOWER BEARINGS
For the lower bearings Landustrie has
three different standard types. The most
recent is the Landy Eco-friendly lower
bearing, with a number of specific
advantages (see the adjacent 3-D sketch)
In the table we have compared the four
different Landustrie lower bearings. All
lower bearings, of any type, only have to
absorb radial forces. The lower bearing
also absorbs the heat expansion and
contraction of the screw.
