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. Today, distributors everywhere rely on Diamond Case to help cut lead times, increase market share and improve profit margins. They know that we respond to quotes faster than competitors and we deliver high-performance product with the same speed.

Speed doesn’t matter if the product quality isn’t there. 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.



At Diamond Case we have brought that same focus on product quality and speed of delivery to an entire Diamond Case line of linear products, including; standard precision steel linear bearings, self aligning linear bearings, pillow blocks and shaft end supports. These new linear bearing products are world class in quality and will be available in both the open and closed options. We look forward to changing the rules again - this time in the linear motion products market.
