Nylon Shaft Solid nylon bar

Nylon rod is an important engineering plastic that can replace the wear-resistant parts of machinery and equipment and replace copper and alloy as wear-resistant parts of equipment. It has good toughness, strong wear resistance, oil resistance, shock resistance, tensile and bending strength, and has the characteristics of small water absorption and good dimensional stability, thus it is used to process various wear-resistant and high-strength parts. Suitable for the production of wear-resistant parts, transmission structure parts, household electrical parts, automotive manufacturing parts, filament textile machinery parts, chemical machinery parts, chemical equipment. Such as turbines, gears, bearings, impellers, cranks, instrument panels, drive shafts, valves, vanes, filaments, high-pressure washers, screws, nuts, seals, bobbins, sleeve jennies, bushing connectors, etc.

Nylon rod is a common plastic material with polyamide as the main component. Nylon rods have good wear resistance, impact resistance, corrosion resistance and high temperature resistance, so they are widely used in machinery manufacturing, bearing manufacturing, gear manufacturing and other fields.

Nylon rods are divided into extruded and cast according to different production processes.

Extruded nylon rods
Nylon 6 (white): This material has the most superior combination of mechanical strength, stiffness, toughness, mechanical shock absorption and wear resistance. These properties, combined with good electrical insulation and chemical resistance, make Nylon 6 a "general purpose" material used in the manufacture of mechanical structural and serviceable parts.
Nylon 66 (cream color): Compared to Nylon 6, its mechanical strength, stiffness, heat and wear resistance, and creep resistance are better, but impact strength and mechanical damping properties are reduced, making it ideal for automatic lathe machining.
Nylon 4.6 (reddish brown): Compared with common nylon, nylon 4.6 is characterized by strong rigidity preservation, good creep resistance, and more heat resistance to aging in a wider temperature range. Therefore, Nylon 4.6 is used in "higher temperature areas" (80 -150 ℃) where Nylon 6, Nylon 66, POM and PET do not meet the requirements in terms of stiffness, creep resistance, heat aging resistance, fatigue strength and wear resistance.
Nylon 66 + GF30 (black): compared with pure nylon 66, this nylon filled with 30% glass fiber reinforcement, its heat resistance, strength, stiffness, creep resistance and dimensional stability, wear resistance and other properties have improved, its maximum allowable use temperature is higher.
Nylon 66 + MOS2 (gray-black): This nylon is filled with molybdenum disulfide, compared with nylon 66, its rigidity, hardness and dimensional stability are improved, but the impact strength is reduced, the grain formation effect of molybdenum disulfide improves the crystalline structure, so that the material bearing and wear resistance are improved.

Casting nylon rod also known as MC nylon: English name Monomer casting nylon, Chinese name monomer casting nylon. "Plastic instead of steel, excellent performance", extremely versatile. It has a variety of unique properties such as light weight, high strength, self-lubrication, wear resistance, corrosion resistance, insulation, etc. It is a widely used engineering plastic, almost in all industrial fields 

Cast nylon rods
MC Nylon (Ivory): The properties of unmodified cast nylon 6 are extremely close to those of nylon 66, with good overall performance, high strength, toughness and hardness, creep resistance, wear resistance, heat aging resistance, good machinability, etc.
MC901 (blue): This modified nylon 6 has a striking blue color, higher toughness, better flexibility and fatigue resistance than ordinary cast nylon, proving to be an ideal material for gears, racks and transmission gears.
Pa6+ Oil (Green): This cast nylon 6 is a veritable self-lubricating nylon, developed specifically for the manufacture of parts that cannot be lubricated, have high loads, and operate at low speeds, greatly broadening the range of nylon applications. It has a lower coefficient of friction (up to 50% lower) and improved wear resistance (up to 10 times higher) than ordinary nylon.
PA6+ Molybdenum disulfide (gray-black): Contains molybdenum disulfide powder, which can improve the load-bearing capacity and wear resistance of unmodified cast nylon without affecting its impact and fatigue resistance, and it is very widely used to manufacture gears, bearings, star wheels and sleeves.
PA6+ solid lubricant (gray): Using the patented formulation of cast nylon 6 with solid lubricant inside, this material has self-lubricating properties, excellent abrasion resistance, outstanding wear resistance and pressure speed capability (5 times higher than ordinary cast nylon). It is especially suitable for high speed running and unlubricated moving parts, and is a perfect complement to oil-containing nylon

Advantages of Nylon Rod

1. Sturdy performance: Nylon rod has excellent sturdy performance. It has tensile strength up to 75-85MPa and yield strength up to 40-50MPa, which is excellent in high strength applications, not easily deformed, and has high strength and stiffness.

2. Wear resistance: nylon rod surface hardness, extremely resistant to wear, and has good self-lubricating properties, more suitable for applications with friction and wear occasions.

3. chemical resistance: nylon rod has relatively good chemical stability, and will not be subject to great degradation and changes under the erosion of various chemical substances.

4. corrosion resistance: nylon rods have excellent corrosion resistance, with good resistance to acid and alkali, grease and other properties.

5. Good processing performance: nylon rods are easy to process and can be processed in various ways, such as mechanical processing, heat deformation processing, injection molding and many other ways.

6. easy to paint: nylon rods have good adhesion and weathering properties, easy to paint and post-treatment processing

Common application of nylon rods

1. Mechanical processing

Nylon rod has high hardness and good toughness, so it is suitable for making various mechanical parts. For example, nylon rods are commonly used as materials in the manufacture of machine tools, lathes, punching machines and other mechanical parts. In addition, nylon rods can also be used to make bearings, guide wheels and other parts.

2. Manufacture of bearings

Nylon rod has good self-lubricating properties, even in the absence of oil lubrication, the bearing and sliding surface can form a lubricating film between them, thereby reducing friction and wear. Therefore, nylon rods are often used in the manufacture of bearings, bushings, sliding rails and other parts with good use.

3. Making gears

Nylon rods have good wear resistance and tensile strength, so they can be used to make gears, hubs and other parts. Gears made of nylon rods can ensure the smoothness of tooth surfaces and involute structure, as well as reduce the friction between tooth surfaces and prolong the service life.

4. Other uses

Nylon rods can also be used to manufacture industrial equipment such as conveyor belts, seals, scrapers, dischargers, etc. And because of its light weight and low price, it is also widely used in some daily necessities and fitness equipment.

Precautions for use

Although nylon rods have many advantages, the following precautions need to be taken when using them:

1. Contact with oxidizing substances will reduce its service life.

2. In high temperature and high humidity environment, nylon rods tend to absorb moisture and swell, which will affect its performance.

3. Avoid contact with many organic solvents for a long time.

4. Avoid direct sunlight on the nylon rods during storage as much as possible.
