Natural PA66 Nylon Rod is a solid engineering plastic round bar used for machining gears, bushings, bearing sleeves, rollers, pulleys, guide wheels, spacers, insulating components and other industrial machine parts. It combines high mechanical strength, good rigidity, abrasion resistance and reliable machining performance.
PA66 is also known as Polyamide 66, Nylon 66, Nylon 6/6 or PA 6.6. The natural material commonly has an ivory, cream-white or slightly yellowish appearance. Its exact color may vary according to the raw-material batch, rod diameter, production process, moisture content and lighting conditions.
Compared with standard PA6, an appropriate PA66 grade is often selected when increased rigidity, mechanical strength and heat resistance are required. However, PA66 is still a moisture-absorbing engineering plastic. Operating humidity, dimensional tolerance, load, temperature and installation conditions should be evaluated before it is used for precision components.

Available reference diameters: Φ20, Φ25, Φ30, Φ35, Φ40, Φ45, Φ50, Φ55, Φ60, Φ65, Φ70, Φ75, Φ80, Φ85, Φ90, Φ95, Φ100, Φ110, Φ120, Φ130, Φ140, Φ150, Φ160, Φ170, Φ180, Φ190, Φ200, Φ220, Φ230, Φ250 and Φ300 mm.
Reference rod length: 1000 mm.
The listed dimensions represent collected manufacturing and market references rather than guaranteed inventory. Not every diameter will necessarily be available from stock at the same time. Large-diameter products such as Φ190–Φ300 mm may require production confirmation, longer lead times or an alternative machining-blank arrangement.
The production method may vary according to rod diameter, material grade and supplier capability. Customers requiring a specific extrusion direction, material certificate, stress condition or dimensional tolerance should confirm these requirements before production.
The raw rod diameter should be larger than the final finished diameter by a suitable machining allowance. A finished component with an outside diameter of 50 mm should not automatically be produced from a nominal Φ50 mm rod.
Machining allowance may be required for:
For precision turning, a larger rod should normally be selected after reviewing the final diameter, tolerance and required surface condition. The necessary allowance depends on the component size and cannot be determined using one fixed value for every product.
Natural PA66 Nylon Rod can be supplied as full-length raw material, cut machining blanks or finished CNC-machined parts. Common finished components include:
| Raw Rod Diameter | Typical Finished Components |
|---|---|
| Φ20–Φ50 mm | Small sleeves, spacers, guide pins, bushings, rollers and insulating supports |
| Φ55–Φ100 mm | Medium rollers, gears, pulleys, guide wheels, bearing sleeves and support components |
| Φ110–Φ180 mm | Large rollers, thick bushings, flanges, pulleys, gears and tensioning wheels |
| Φ190–Φ300 mm | Large gear blanks, heavy rollers, pulley blanks, thick rings and special industrial components |
The examples above are general references. The appropriate rod diameter must be selected according to the finished drawing, machining allowance, material stress, equipment load and required dimensional accuracy.
Unmodified PA66 rod is commonly described as natural, ivory or cream colored. It should not necessarily be expected to have the bright white appearance of a pigmented plastic.
Normal appearance variations may include:
The surface and color of a small-diameter extruded rod may differ from those of a large-diameter machining blank. Color alone cannot confirm the exact polymer grade, raw-material source or special performance.
Natural PA66 Nylon Rod can be processed using CNC lathes, machining centers, milling machines and drilling equipment. Available operations include:
Appropriate cutting tools, feed rates and cooling methods should be used to avoid excessive heat, surface melting, burr formation or dimensional changes. Compressed air or a suitable plastic-machining coolant may be used according to the component and equipment conditions.
Large-diameter PA66 rods may contain residual stress generated during forming and cooling. Removing a large amount of material from only one side can release the stress unevenly and cause bending, ovality or dimensional movement.
For precision components, an appropriate machining sequence may include:
The necessary process depends on the finished component dimensions, wall thickness, tolerance and operating requirements. Not every nylon part requires the same stress-relief procedure.
PA66 absorbs moisture from its surrounding environment. Moisture absorption may affect dimensions, stiffness, toughness, electrical properties and finished-part tolerances.
This characteristic is particularly important for components used in:
For precision components, customers should provide the expected operating temperature, humidity, water exposure, assembly method and dimensional tolerance. Metal-part interference fits and tolerances should not be copied directly to PA66 without considering moisture and temperature effects.
| Comparison Item | PA66 Nylon Rod | PA6 Nylon Rod |
|---|---|---|
| Rigidity | Generally selected when increased rigidity is required | Generally offers a useful balance of strength and toughness |
| Heat Resistance | Typically higher for comparable unmodified grades | Generally lower than comparable PA66 grades |
| Mechanical Strength | Often selected for higher-strength structural components | Suitable for many general mechanical and wear components |
| Impact Performance | Depends strongly on grade and conditioning | Often selected where increased toughness is important |
| Moisture Absorption | Must be considered for dimensional and electrical performance | Must also be considered for precision components |
| Machining Availability | Some large sizes may require production confirmation | Generally available in a broad range of standard and cast stock forms |
The final selection should be based on the actual grade rather than only the terms PA6 or PA66. Reinforcement, lubrication additives, heat stabilization, moisture conditioning and manufacturing process can significantly affect performance.
Standard natural PA66 should not automatically be described as food grade, flame retardant, anti-static, conductive, heat stabilized, UV resistant or glass-fiber reinforced.
Natural PA66 Nylon Rod is used as machining stock for industrial equipment requiring strength, rigidity, abrasion resistance, reduced weight or electrical insulation.
Typical industries and equipment include:
To select the correct rod and production method, customers should provide:
Raw-material inspection may include material identification, outside diameter, overall length, straightness, surface condition, color and visible defects.
Finished-part inspection may include:
For batch production, an initial sample can be inspected before processing the remaining quantity. Dimensions should be evaluated according to the confirmed drawing and agreed inspection conditions rather than only the nominal rod diameter.
