Heavy-duty cast nylon for wear-resistant, load-bearing and machined components.
Blue Cast Nylon Rod combines good mechanical strength, toughness, fatigue resistance, wear resistance and useful sliding properties. Its larger diameter range makes it well suited to machining bushes, rollers, pulleys, guides, cams, wear components and other substantial industrial parts.
Need a larger Blue Cast Nylon diameter?
Tell us the diameter, quantity and application requirements. Larger diameters may be specifically imported or added to one of our scheduled overseas shipments.
Everything you need to choose with confidence.
Is Blue Cast Nylon Rod right for my application?
Blue Cast Nylon is a strong choice for larger machined components requiring toughness, wear resistance, mechanical strength and fatigue resistance.
It is commonly considered for bushes, rollers, pulleys, guides, cams, sleeves and wear components where a larger starting diameter is required.
Nylon absorbs moisture, so applications involving wet or humid conditions and very close finished tolerances need to take dimensional movement into account.
Key properties and benefits
- Good mechanical strength for larger engineering components.
- Excellent wear resistance for suitable sliding and moving applications.
- Good fatigue resistance for components exposed to repeated mechanical loading.
- Good toughness where parts may experience impact or shock.
- Useful sliding properties for bushes, rollers, guides and similar components.
- Mechanical damping can help reduce transmitted vibration and noise.
- Machinable using conventional turning, milling, drilling and boring equipment.
Common applications
Blue Cast Nylon Rod is commonly machined into:
- Bushes and bushings
- Sleeve bearings
- Large rollers
- Guide rollers
- Pulleys
- Cams
- Wear pads and wear components
- Sleeves
- Spacers
- Guides
- General industrial machined components
Available diameters and rod length
Our standard stocked Blue Cast Nylon Rod range is:
| Colour | Blue |
|---|---|
| Stocked diameters | 40mm through to 100mm |
| Rod length | 1000mm only |
Select your required stocked diameter using the product options above to view current pricing and availability.
Rod is supplied as engineering machining stock. Where a precise finished diameter is required, allow appropriate machining allowance.
Need a Blue Cast Nylon diameter larger than 100mm?
Yes. Larger Blue Cast Nylon diameters may be available by special order.
Depending on your requirement, larger rods can be specifically imported or added to one of our scheduled overseas shipments.
Because these sizes are outside our normal stocked 40–100mm range, lead time and availability depend on the diameter, quantity and import schedule.
Send us the required diameter, quantity and application details and we can investigate supply options.
Cast Nylon vs Extruded Nylon — which should I choose?
Both are Nylon engineering plastics, but their manufacturing methods and stock sizes suit different types of components.
Blue Cast Nylon vs Black and Natural Cast Nylon
Blue, Black and Natural Cast Nylon all serve as larger-diameter engineering rod stock, but the best choice depends on the application and any documentation requirements.
Does Blue Cast Nylon absorb moisture?
Yes. Nylon is hygroscopic, meaning it absorbs moisture from the surrounding environment.
Moisture absorption can cause dimensional change and influence some mechanical properties.
This is particularly important for larger components with close finished tolerances, especially where the part operates in wet or humid conditions.
Where low moisture absorption and strong dimensional stability are more important, Acetal may be worth considering.
Machining Blue Cast Nylon Rod
Blue Cast Nylon can be turned, milled, drilled and bored using conventional machining equipment.
Sharp tooling, controlled feed rates and good chip clearance help reduce heat build-up and improve surface finish.
Larger Nylon components may move as material is removed, so machining strategy and dimensional allowance should be considered where close finished tolerances are required.
Moisture and temperature conditions should also be considered where finished dimensions are critical.
Blue Cast Nylon vs Acetal and HDPE — which should I choose?
The best engineering plastic depends on the mechanical, dimensional and environmental requirements of the finished part.
Oils, fuels and chemical resistance
Blue Cast Nylon offers useful resistance to many oils, greases and fuels, which makes it suitable for many mechanical and industrial environments.
Chemical suitability should still be checked for the specific substance, concentration, operating temperature and exposure time.
If chemical exposure is important to your application, contact Warlond Plastics before ordering.
