Black Acetal Plastic Rod - 100mm To 250mm Dia.

These black acetal plastic rods provide a strong, rigid engineering material ideal for precision-machined components. Supplied in a range of diameters from 100mm to 250mm and standard lengths from 100mm up to 1500mm, they offer excellent dimensional stability and a high-quality surface finish for demanding industrial applications.

Combining high stiffness, low friction and good wear resistance, black acetal rod is widely used for bearings, bushes, gears, rollers, guides and structural parts in mechanical, automotive, food-processing and general engineering environments.

Product Features

• Material: black acetal (POM) engineering plastic for high stiffness and excellent machinability.
• Diameter range: from 100mm up to 250mm to suit both medium and large structural or load-bearing components.
• Length options: standard cut lengths of 100mm, 250mm, 500mm, 1000mm and 1500mm, plus a wide choice of additional sizes to minimise waste.
• High-quality, smooth extruded finish for improved sliding performance and reduced post-machining finishing work.
• Good dimensional stability and low moisture absorption to maintain tight tolerances in service.
• Black colour for discrete installations, reduced light reflection and easy differentiation from natural/acetal variants.
• Suitable for further processing by turning, milling, drilling and tapping using conventional metalworking tools.

Key Features and Benefits

• Excellent wear and abrasion resistance helps extend service life of moving or load-bearing parts, reducing maintenance downtime.
• Low coefficient of friction supports smooth, quiet operation in sliding and rotating assemblies without excessive lubrication.
• Stable mechanical properties and low water uptake support consistent performance in varied industrial environments.
• Good machinability allows accurate, close-tolerance components to be produced quickly with standard workshop equipment.
• High strength and rigidity make the material a reliable alternative to metals for weight reduction and corrosion resistance.
• Wide choice of diameters and cut lengths helps optimise material usage and lower machining and offcut waste.

Specifications

Applications and Ideal Uses

Black acetal rods are suitable for a wide range of precision-engineering and industrial uses where tough, low-friction components are required.

• Machined bushes, bearings, rollers and wear strips in conveyor and handling systems.
• Gears, cams and drive components in mechanical and automation equipment.
• Guides, slides and support blocks in jigs, fixtures and production machinery.
• Structural spacers, mounting blocks and replacement parts in plant maintenance.
• Prototype and small-batch machined components where metal alternatives are heavy or prone to corrosion.

Frequently Asked Questions

Can I machine black acetal rod with standard workshop tools?

Yes, black acetal rod can be machined using conventional metalworking tools such as lathes, milling machines and drills. Sharp tools and appropriate cutting speeds are recommended to achieve a smooth finish and maintain dimensional accuracy.

How do I choose the correct diameter and length for my application?

Select a diameter that provides sufficient strength and bearing area for the loads involved and allows for any machining allowances. Choose from the available length options, such as 100mm, 250mm, 500mm, 1000mm or 1500mm, to minimise waste after machining your final part.

Is black acetal suitable for use in damp or humid environments?

Black acetal has low moisture absorption compared with many other plastics, so it maintains its mechanical properties and dimensions well in damp or humid conditions. However, always check the specific demands of your application, particularly if continuous hot water or chemical exposure is expected.
