SIX DIFFERENT TYPES OF BALL BEARING MATERIALS
Steel is commonly used for both the rolling component and the rings in roller bearings and ball bearings. Other properties, such as higher corrosion resistance, porosity, cost savings, seizure resistance, lightweight materials, and high durability, are required in various industrial applications.
FEIKEN Bearing, being Malaysia’s preferred bearing supplier, knows everything about obtaining the correct bearing components and materials for your machine.
1.0 Carbon Steel
Carbon steel, sometimes known as ‘commercial grade,’ is not stainless steel and contains up to 2.1 percent carbon by weight. The stronger the bearing, the higher the carbon concentration. However, it becomes less ductile, has a lower melting point, and is unable to handle big loads or at fast speeds as a result of this. Carbon steel bearings have several advantages, including being the cheapest bearing material and being extremely hard. Carbon bearings are typically found in rolling drawers, locks, bicycles, roller skates, and shopping carts.
2.0 Chrome Steel
Chrome steel bearings are another sort of steel bearing, and they are one of the most popular types of bearing components and materials because of their low cost, high hardness, and lower working volume. A chrome steel bearing, contrary to its name, has a low chromium content in the steel compound. The advantages of employing a chrome steel bearing include high hardness, high load capacity, low decibel, affordable cost, and broad accessibility. It does, however, require lubrication and is not corrosion or chemical resistant. It has a wide range of industry applications as one of the most regularly supplied bearings. Vibrating motor systems, food processing equipment, and linear motion components are just a few examples.
3.0 Stainless Steel
Stainless steel is the last steel material utilised to make industry-ready bearings. The carbon content is lower than carbon steel bearings, while the chromium content is higher than chrome steel bearings. Most other bearing types are less effective, accurate, robust, durable, corrosion resistant, chemical resistant, softer, and temperature adaptable than stainless steel bearings. The only disadvantages would be the heavier content, lubrication requirements, and greater expenses. The stainless steel bearing may now be utilised in a variety of industrial applications, including temperature-sensitive ones. Food processing, manufacturing, metal plating, instrumentation, extreme humidity, and highly chemical regions are just a few examples.
Ceramic bearings are made using two ceramic rings and a fluorine resin retainer to make a very non-corrosive and durable bearing. Due to the non-magnetic requirements of the machinery, this material was chosen above stainless steel and its variations. A ceramic ball bearing has a high hardness, is anti-corrosive, robust, lightweight, high-temperature resistant, low density, and requires little maintenance because it does not require oil. Ceramic ball bearings are frequently used in aeroplanes, dental equipment, and food processing facilities.
Because of their lightweight properties, numerous non-metallic materials are employed to make ball and roller bearings. The following plastics and polymers are utilised in the bearing industry:
- Nitrile Rubber
- Nylon Silicone
- Teflon (PTFE)
Polymer plastic bearings have large temperature ranges and inherently low friction qualities, which means they don’t require lubrication. Other advantages of polymer plastic bearings include corrosion, chemical, and rust resistance, as well as a lightweight, high-strength body that may be employed in a variety of industrial machinery. Electrical switch gears, water turbines, ship propeller shafts, home appliances, filming gear, instruments, textiles, factory floor applications, and more all require polymer plastic bearings.
Finally, hybrid bearings are created according to industry standards. They offer electrical insulation by using steel rings with strong radial and axial strength, as well as bearing quality silicone nitrate for the rolling parts. Hybrid bearings offer superior wear resistance, a wide range of industry application situations, faster speeds than most, and non-conductive components for temperature increases or RCF. The hybrid bearing components and materials are used in high-level research and scientific machinery such as cryogenic chambers, aeronautical engineering, and medical equipment.
