Properties and Material Options of Nylon Bushings and The Benefits
Nylon is one of the most versatile synthetic materials, which finds use in everything from daily life to industry. Experts can readily separate nylon, a form of plastic, into fibers. It may be readily shaped into commonplace items for the creation of amenities. Nylon is by our side for virtually our entire lives. After cleaning your teeth with a nylon-bristled toothbrush, you may jump over the nylon carpet to the kitchen and eat your meals in a nylon bowl. One uses a nylon umbrella as a roof to leave the house in the bright sun or to stay dry.
Nylon Properties and Material Options
Nylons are frequently defined using numbers that relate to their molecular configurations, such as 6, 66, 11, 12, etc. Nylon Bushings come in many different varieties, but the two that are most frequently seen in sheet, rod, and tube form are Nylon 6 and Nylon 6/6.
The mechanical, thermal, and electrical characteristics of nylon 6 and 6/6 are very comparable. Both come in a range of colors and formulas that are tailored to satisfy the requirements of certain applications. View our graphic to learn more about Nylon 6 chemical resistance.
Typically, a liquid casting method is used to create sheets, rods, and tubes out of nylon 6. The most economical way to produce big diameter rods, tubes, and thick sheets is often casting. The ability for manufacturers to produce unique near net (irregular) forms is a benefit of this approach. In the manufacture of pieces that would yield poorly from normal sheet, rod, or tube stock, near net forms are helpful.
The thermoplastic extruder is often used to melt solid polymer pellets to create nylon 6/6- sheet, rod, and tube. Extraction is a quick and cost-effective process for producing thin sheets, rods, and tubes with tiny diameters. Extruded Nylon 6/6 sheet, rod, and tubing may be produced to any length, unlike cast Nylon 6 stock forms, which might be economically advantageous for producing completed parts.
Grades of Nylon: Nylon is offered in a number of specialized formulae. Oil- and molybdenum disulfide-filled nylons offer improved wear characteristics that frequently negate the requirement for additional lubrication. Nylon that has been heat-stabilized can operate at greater temperatures. Glass-filled grades of nylon are offered for improved stiffness and strength. For direct food contact, Nylon Bushings are available in FDA-compliant grades.
Nylon with a Metal Core: Gears, rollers, sprockets, and augers are just a few examples of the various components that may be made from nylon billets. The performance benefits of nylon and metal are combined into a single cohesive unit in NYMETAL billets for power transmission applications.
Characteristics of the bushing of this polymer:
These bushings are self-lubricating, which means that lubrication is not necessary. They are practically zero-maintenance bushings as a result. They also have a very low coefficient of friction. They are non-galling and have a robust hardness of around 80 D.
Performance and strength:
The PV (pressure-velocity) rating of non-reinforced Nylon Bushings is 3000 ft/min/psi. Unreinforced nylon has a tensile strength of 12 Ksi, compressive strength of 15 Ksi, and flexural strength of around 15 Ksi. Additionally, they are far lighter than their metal equivalents.
When hydrocarbons and alcohols are included, certain nylons perform remarkably well. Their main vulnerability is strong acids. Chemically, nylon is resistant to the majority of fuels, weak acids, alkalis, and organic solvents.
The working temperature of molded Nylon Bushings is around 250°F. The cryogenic temperatures are inappropriate for them. Its thermal expansion coefficient, which is relatively low at 5.510-5in/in/°F, indicates that it will remain dimensionally stable even when exposed to large temperature fluctuations. Nylon’s hygroscopic nature must be taken into account in design specifications because of its typical moisture absorption rate of 3–7%.
Advantages of Nylon Bushings for Design Engineers
Don’t rule out nylon as a material choice while searching for polymer sleeve and flanged bushing solutions. Tolerances for injection molding can be quite tight.
Nylon bushings are:
With a maximum continuous operating temperature of around 250°F, they are dimensionally stable. Numerous engineers who wanted to save weight and money while retaining dependable performance have chosen them because of their wide range of chemical resistance.
