Custom Bronze Bushing | Perforated Copper Alloy Sleeve

Custom Copper Alloy Sleeves and Industrial Bushings with Holes

Product Overview

This product is a cylindrical industrial machinery component featuring a hollow structure, a machined inner bore, holes on the outer surface, and mounting features at the ends. The sleeve body, inner bore dimensions, outer diameter, length, hole distribution, and end-face configurations can all be customized according to equipment assembly requirements and customer drawings.

When specified as a copper alloy sliding bushing, the component serves functions such as sliding support, guiding, wear protection, and lubrication interfaces for shaft assemblies. Specific functionality depends on the material grade, the purpose of the holes, fit tolerances, and equipment operating conditions.

Hongsinn Precision evaluates part design, manufacturing processes, and inspection requirements based on customer needs, providing comprehensive custom manufacturing support—from prototype development to mass production—for OEM/ODM projects.

Technical Specifications

Product Features

1. Customized Cylindrical Structure

The inner bore, outer diameter, length, wall thickness, and end connection configurations can be designed based on customer drawings to meet the installation requirements of various equipment.

2. Multi-feature Design

Holes, recesses, or other features can be machined into the outer surface according to design specifications. If intended for lubrication, the hole placement and oil channel layout can be designed to suit the specific lubrication method.

3. Precision Machining of Inner Bores

Inner bores and mating surfaces are machined according to drawing specifications, with dimensions, tolerances, and surface roughness controlled to meet assembly requirements.

4. Diverse Material Options

Materials such as copper alloys, bronze, brass, steel, or other suitable materials can be evaluated based on actual operating conditions. The final material selection is determined by the specific grade and technical specifications confirmed by the customer.

5. OEM/ODM Custom Manufacturing

We support structural evaluation, process planning, and custom manufacturing based on 2D engineering drawings, 3D CAD models, or qualified samples.
