Bearing cages are essential components in rolling element bearing operation. They play a key role in maintaining the spacing between rolling elements (such as balls or rollers), guiding their movement, and reducing friction. Without bearing cages, the rolling elements would clump together, resulting in increased friction, heat and wear, and ultimately premature bearing failure. NSAR can make cages of any material to provide the bearing you want.
“Nylon” refers to a class of plastics known as “polyamides”. Nylon is typically characterized by the amide group (CONH) and covers a wide range of material types (such as nylon 6,6, nylon 6,12, nylon 4,6, nylon 6, nylon 12, etc.), providing an extremely wide range of properties. Nylon is used to produce films and fibers, and can also be used as a molding compound.
Most nylons are semi-crystalline, generally very tough, and have good heat and chemical resistance. Different types of nylon have very different properties, with specific gravity, melting point and water content decreasing as the amount of nylon increases. Nylon can be used in high temperature environments. Heat stabilized systems can maintain performance at temperatures up to 185 oC (for reinforced systems).
Steel, an alloy of iron and carbon with up to 2% carbon content (materials with higher carbon content are defined as cast iron). By far the most widely used material is in building the world’s infrastructure and industry, steel is used to make everything from sewing needles to oil tankers. In addition, the tools needed to build and manufacture these items are also made of steel.
Iron is made by removing oxygen and other impurities from iron ore. When iron is combined with carbon, recycled steel and small amounts of other elements, it becomes steel.
Steel is an alloy of iron and carbon, containing less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulfur and oxygen. Steel is the world’s most important engineering and construction material. It is used in every aspect of our lives, including cars, building products, refrigerators, washing machines, cargo ships and surgical knives.
Steel is durable and adaptable.
Advantages of steel include ease of mass production and prefabrication, uniform quality, lightweight design, economical transportation and handling, and quick and easy installation.
When choosing, you should choose according to the application requirements. For example, if you need low noise for electrical appliances, you should choose nylon cage bearings. For high temperature, high load, and high vibration equipment, stamped steel cages or machined bronze bearings should be preferred.
When comparing nylon and stainless steel components, you need to understand their relative advantages and disadvantages.
Durability and Strength:
Nylon parts are durable in light applications, but are not as efficient in high pressure applications.
Stainless steel parts provide unparalleled durability and strength for heavy applications.
Environmental Resistance:
Stainless steel materials are corrosion-resistant and high temperature-resistant, suitable for the harshest environments.
Nylon parts are chemically resistant, but are less effective in extreme heat or UV exposure.
Weight and Handling:
Lightweight makes nylon easier to carry, transport and install.
Steel is heavier but provides a solid foundation for permanent load-bearing structures.
Cost Factors:
Nylon parts are less expensive and provide a value-based solution for less critical applications.
Stainless steel parts are more expensive but offer better value in the long run due to their durability.
Aesthetic and Hygienic Properties:
Stainless steel is aesthetically pleasing and easy to maintain. For applications that require aesthetics and hygiene, such as kitchen appliances and medical devices, stainless steel is the first choice.
Nylon’s color and functional options provide great flexibility and can be easily used in concealed or non-aesthetic applications.
