Diamond Case

For nearly 20 years, Diamond Case has been changing the rules in linear shafting. We’ve taken a no-nonsense approach – no fancy packaging or marketing. We’ve focused on what matters: high quality product and fast turnaround on request for quotations and on order shipments. Every Diamond Case shaft meets or exceeds the industry’s highest standards. For going on 20 years, Diamond Case customers have relied on our product for superior case hardness, roundness, cylindricity, straightness and consistency of finish. Induction hardened and precision ground, our shafting is produced to the demanding tolerances required by the linear motion industry.
