Stainless precision ground needle pins – drawn, then centerless-ground to final diameter. Ground pins run true to sub-micron surface finish, which is what pivot and needle-bearing applications demand for wear life.
Function and Design
Needle parts live at the extreme of slenderness, where straightness beats everything – a bent needle ruins the assembly it serves. Ours are drawn or ground, stress-relieved, and checked for runout along the full length before packing.
Design Highlights
- Stainless construction means no coating to fail in washdown or humid conditions.
- Because tooling is in house, volume pricing improves as quantities rise.
- Trial lots can be run before you commit to volume.
- Material: For the ground needle pin we default to stainless steel (304 / 316); the grade is locked before tooling starts.
- Process: drawn-tube production for the ground needle pin with anneal windows logged per batch.
- Finish: Surface treatment is chosen for the duty the ground needle pin sees: plated, coated or natural per print.
- Size: The ground needle pin is built to your drawing – the family covers the common range, your dimensions are quoted per print.
- Custom: OEM/ODM to drawing; free samples of the ground needle pin and a manufacturability review before tooling.
Applications
In service you will find this part in medical and food-grade devices, instrument capillary lines, temperature probe assemblies.
Factory-Direct Advantage
The ground needle pin is small in the bill of materials and large in the warranty claim when it goes wrong. The ground needle pin is produced to print, with the features that carry function inspected first.
