PA12 Nylon Rod is a low-moisture-absorption polyamide 12 round bar offering good dimensional stability, toughness, chemical resistance and machining performance. It is suitable for precision bushings, rollers, sleeves, guide blocks, insulation components and automation equipment parts. Recommended reference sizes include Ø20, Ø25, Ø30, Ø40, Ø50, Ø60, Ø80 and Ø100 mm × 1000 mm, with 500 mm and 1000 mm common lengths.
PA12 Nylon Rod is a polyamide 12 round bar designed for precision-machined components requiring low moisture absorption, good dimensional stability, toughness and reliable chemical resistance. Compared with PA6 and PA66 nylon, PA12 absorbs less moisture, helping finished parts maintain more stable dimensions in humid or changing operating environments.
The material combines relatively low density with good impact strength, flexibility and resistance to oils, fuels and many industrial chemicals. It is suitable for components that require a balance of mechanical performance, dimensional stability and reduced sensitivity to environmental moisture.

PA12 is also known as polyamide 12 or nylon 12. General information about its structure, properties and applications is available from Wikipedia’s Nylon 12 explanation.
PA12 Nylon Rod can be machined into precision industrial components such as:
PA12 is particularly suitable for parts where moisture-related dimensional change must be reduced. The final material grade should be selected according to load, operating temperature, chemical medium, tolerance, friction conditions and service environment.

Size notice: The dimensions listed above are reference production and sales specifications taken from the supplied image. They do not represent guaranteed stock availability. Actual diameter, length, material grade, color, minimum order quantity, machining allowance, straightness and tolerance should be confirmed before production.
Small-diameter rods, large-diameter rods, special colors and modified PA12 grades may use different manufacturing processes and minimum order quantities. Finished components can also be produced according to customer drawings, physical samples and assembly requirements.
PA12 Nylon Rod can be processed by CNC turning, milling, drilling, boring, cutting, grooving, tapping and chamfering. Our CNC Plastic Machining service supports prototype production and batch manufacturing according to drawings, samples and actual working conditions.
Sharp cutting tools, suitable feed rates and controlled cutting temperatures are recommended during machining. Excessive heat should be avoided to reduce surface melting, burr formation and dimensional variation.
Although PA12 absorbs less moisture than PA6 and PA66, temperature, humidity and long-term loading can still affect finished dimensions. Precision parts should therefore be designed with appropriate machining allowances and installation clearances.
PA12 Nylon Rod is suitable for customers requiring a lightweight, machinable polyamide material with low moisture absorption, dependable toughness and improved dimensional stability. Material grade, rod diameter, color, machining allowance and finished component structure can be selected according to the actual application.
Check drawings for full specifications and confirm materials according to service conditions to prevent product defects.
Inspect all key processing steps and fully verify dimensions, holes, grooves and fitting surfaces.
Deburr, chamfer and clean products for easy installation. Ensure uniform quality among batch products.
Choose appropriate packaging solutions based on product features to protect goods from collision, deformation and mixing during transit.
Unlike metal parts, engineering plastic components still require strict control over dimensions, holes, edges, surface, materials and assembly performance for equipment use.
Engineering plastic parts suit friction, guide, support, buffer, anti-corrosion and insulation areas. We supply UHMWPE, POM, PA, PP/PE components for conveyor, food, mining, machinery, chemical and cable systems, with custom OEM service available.
