How to Specify a Custom Bushing: 6 Questions to Answer First
Before you send a drawing to a machine shop, answer these six questions. They cover 90% of the back-and-forth we see on first-time custom bushing projects.
316 Stainless vs 6061 Aluminum: Which Bushing Material Is Right for Your Application?
Aluminum wins on weight and cost; stainless wins on corrosion and wear. Here is the decision framework our engineers actually use.
Keyed vs. Threaded Bushing Ends: Choosing the Right Power Connection
Three ways to transfer torque — keyed, threaded, and press-fit journals. Picking the wrong one is the most common cause of failure on newly installed bushings.
What ISO 9001 Means for Your Bushing Quality and Traceability
A certification plaque on the wall does not machine better parts — but a real QMS does. Here is what certification changes in practice.
