Recessed H-Flange Bushings for Carton-Erector Pickup Heads
A carton-erector pickup head can move on parallel rods while vacuum cups pull a blank away from a stack. This enquiry concerns the rod sleeves in the moving head plate, where a recessed H-flange arrangement must fit between cup brackets and pneumatic fittings.

Recessed Round-Flange Bushings for Inspection-Fixture Locator Carriers
A retractable locator carrier in an inspection fixture may slide on guide pins while a separate datum pin locates the workpiece. This page covers the recessed sleeve supporting the carrier, with emphasis on the tolerance chain between its mounting pocket, guide pin and inspection datum.

A machine access hatch can place a cantilever load on its hinge pins as it opens. This application page covers a bolted graphite-plugged flange sleeve where a countersunk fastening face must remain clear of a nearby hinge leaf or cover panel.

Core Machining Capabilities
Boniu machines custom copper-alloy bushings to customer drawings. Choose the alloy and standard before confirming dimensions and inspection requirements.
| Capability | Range / specification |
|---|---|
| Dimensional tolerance | Confirmed after review of the drawing, material, geometry and inspection requirements. |
| Machining size | No fixed size limit. Custom bore, outside diameter and length to drawing; final manufacturing feasibility confirmed during review. |
| High-tensile brass | CuZn25Al5Mn4Fe3; GB, US and EN reference grades listed separately below. |
| Other brass materials | H59 and H62 brass. |
| Tin bronze options | C93200, C90700, C93700 and C90500; specify the exact grade and casting standard with your drawing. |
| Quotation inputs | Drawing, units, alloy and standard, tolerances, quantity and operating conditions. |
Brass and Bronze Material Grades
Our four tin bronze options are C93200, C90700, C93700 and C90500. Regional grades below are comparison references, not a declaration of interchangeability.
| Material family | China / GB reference | US / UNS reference | Europe / EN reference | Relationship |
|---|---|---|---|---|
| High-tensile brass | ZCuZn25Al6Fe3Mn3 | C86300 | CuZn25Al5Mn4Fe3-C / CC762S | Related alloys; Al/Mn limits differ. |
| H59 brass | H59 / T28200 | C28000 | CuZn40 / CW509L | Reference only; Cu and impurity limits differ. |
| H62 brass | H62 / T27600 | C27400 | CuZn37 / CW508L | Reference only; Cu limits differ. |
| Tin bronze: C93200 | No exact GB match declared | C93200 | CuSn7Zn4Pb7-C / CC493K | Related leaded bronze; GB 5-5-5 is a separate alloy. |
| Tin bronze: C90700 | ZCuSn10P1 (comparison) | C90700 | CuSn11P-C / CC481K (comparison) | Phosphorus and tin limits differ; no automatic substitution. |
| Tin bronze: C93700 | ZCuPb10Sn10 | C93700 | CuSn10Pb10-C / CC495K | Related 10-10 alloys; impurity limits differ. |
| Tin bronze: C90500 | ZCuSn10Zn2 | C90500 | CuSn10-C / CC480K (comparison only) | No direct EN equivalent declared; CC480K has much less Zn. |
| Additional 5-5-5 reference | ZCuSn5Pb5Zn5 | C83600 | CuSn5Zn5Pb5-C / CC491K | Correct 5-5-5 reference family; not C93200. |
