IllustrationAutomation & motion
Choose the shaft, bushing or locating pin for your machine. Connect its mating fit and functional datums to the checks needed before the first build.
IllustrationInstruments & sensors
Connect the sensor tube, process connection and guide sleeve. Define the geometry that controls mounting, internal clearance and assembly space.
IllustrationFluid connections
Review the adapter, valve stem and seat as connected interfaces. Threads, passages and contact surfaces each have a different job.
IllustrationElectronic hardware
Plan the enclosure, mounting plate and standoffs around your board and connectors. Keep mechanical clearance and visible-surface requirements together.

Blind Tapped Holes: Specify Usable Thread, Not Just Hole Depth
Separate full thread length, tap runout and drilled depth so a screw can develop the intended engagement without bottoming out.
