Are Lead Screws for you?

Lead screws are a lower cost linear motion solution than any other mechanical, pneumatic or hydraulic product. Precision lead and acme screws are manufactured from special high carbon alloy steels and anti-corrosive stainless steels that lend themselves to precision thread-rolling processes and to the demanding applications where engineers apply them.
