LubricationOil Lubrication
Oil-lubricated sleeves and bushings should be specified through their bore, mating surfaces and selected alloy. This enquiry covers custom sand casting and CNC machining, with tin-bronze, brass and copper requests and named CuZn25Al5Mn4Fe3 or CuSn8P material choices. Drawings and samples can be used to define the requested component.
Control the bushing fit through the drawing
Dimension the bore and outside interfaces from the references used by the assembly. Identify any flange or contact face relevant to the design, together with the finished limits required for installation. A sample enquiry should explain which dimensions and conditions the new component must reproduce.
Select the alloy for the actual lubrication and duty
Choose the complete material designation and applicable standard for the part. CuZn25Al5Mn4Fe3 and CuSn8P are separate choices, with oil lubrication named for the component enquiry. Describe the load, movement and operating environment relevant to the design so the required grade and service acceptance can be evaluated.
- Provide the bushing or sleeve drawing, or sample reference.
- Identify the selected alloy and required quantity.
- Specify bore, mating dimensions and finished surface requirements.
- Describe the oil-lubrication arrangement and intended duty.
Define casting and CNC-finished surfaces
Specify the casting geometry and the interfaces requiring CNC machining. Customized color is available for enquiry, while flange and washer components are additional part types. Identify the actual deliverable and its required condition rather than applying a bushing specification to every component form.
Translate qualitative properties into acceptance requirements
High load capability and good corrosion resistance are stated characteristics. Define the operating conditions and acceptance criteria needed by the project. Those requirements, together with the selected alloy and finished dimensions, establish the ordered component without assuming a numerical load or speed rating.
