Product Details
This brass roller pin is designed for compact mechanisms that require smooth rotation, stable support, and reliable axial guidance. With a height of 0.375 in and a 1/16" drilled center hole, the part is engineered for small assemblies such as miniature rollers, light-duty motion components, and custom mechanical linkages. The stepped outer profile and clean cylindrical geometry help the pin seat firmly into mating housings while allowing controlled rotational movement on the top section.
Material & Manufacturing
The pin is machined from C38500 or C38000 brass, compliant with ASTM B455. Both alloys provide excellent machinability, good strength, and clean surface finishing characteristics. These materials are well-suited for components that require smooth, burr-free surfaces and stable performance in dry or lightly lubricated applications.
A 63 micro-inch surface finish is maintained across functional areas, ensuring consistent rotational behavior and minimal friction when installed in its mating assembly.

FAQ
Q: Can the diameter and height be customized?
A: Yes. Dimensions, tolerances, and the step profile can be adjusted based on your assembly or roller requirements.
Q: What tolerance can you provide for the drilled hole?
A: 1/16" holes are typically held to tight tolerances suitable for pins, shafts, or insert-fit applications; specific tolerance requests can be accommodated.
Q: Is the surface finish suitable for moving assemblies?
A: Yes. The 63 µin finish ensures low friction and smooth operation, especially for light-duty rotational movement.
Q: Do you offer other brass grades if needed?
A: Alternative brass grades or even stainless steel or aluminum options can be produced depending on application requirements.
Q: Are burrs removed from the drilled hole?
A: Yes. All edges are deburred to ensure proper fit and to prevent wear on mating parts.
