Is your equipment Stainless steel Bearing Bushing rusty?
The bushings, if rusted, will cause the bearings to run stuck and also affect the positioning accuracy and even greatly affect the life of its bearing equipment as well. In fact, a metal part in another metal part on the smooth movement, lubrication is necessary, commonly used is lubricating oil and grease. Without these lubricating substances or without regular relubrication, the system will fail. Grease, however, does keep metal bearings running properly, but it can also be extremely troublesome in many applications. Grease on the operator’s fingers is one thing, grease in the surrounding environment is another. In the production and packaging of food or pharmaceutical products, in clean rooms where highly sensitive chips are produced, as well as in the medical technology sector and in the paper industry, lubricating grease is seen as contamination rather than an unavoidable harmful substance. A hundred attempts have been made to solve this problem.
Plain Bearings & Gear Bearings – Low Friction Bearings flange Bushing
Metal self-lubricating bearing plain bearing: Plain bearings made of high-performance metal oil-free bearings can solve the conflict between lubricating grease and a hygienic and clean environment. This self-lubricating bearing already has a solid lubricant built into the manufacturing process, so no additional external lubrication is required.
Bushing with solid lubricant: From a technical point of view, self-lubricating bearings can also meet the high requirements of precision and hardness, so a lubrication-free self-lubricating bearing solution is perfectly feasible and also helps prevent unnecessary lubricating grease from polluting the environment. If you’re still busy with rail descaling and maintenance, it’s time to make a change! Replace with stainless steel self-lubricating bearings

Key Differences Between Stainless Steel Bearings and Ordinary Bearings
Both stainless steel bearings and ordinary bearings are used in various industrial applications, but they differ in several crucial aspects:
- Material: Stainless steel bearings are made from chromium-containing steel, offering excellent rust and corrosion resistance. This makes them ideal for harsh environments. In contrast, ordinary bearings are typically made from carbon steel, which is less resistant to corrosion but more affordable.
- Durability: Stainless steel bearings tend to have a longer lifespan due to their corrosion resistance, making them suitable for applications where longevity is important.
- Load Capacity: The load capacity depends on size and material. Stainless steel bearings generally have higher load capacity due to their superior yield strength compared to carbon steel.
- Cost: Stainless steel bearings are more expensive due to the material and manufacturing process, but their extended lifespan and corrosion resistance can justify the higher cost over time.
In summary, the choice between stainless steel and ordinary bearings depends on the specific application’s environmental conditions, load capacity, and cost constraints.
Comparison: Stainless Steel 316 vs. Stainless Steel 304 Bushings
Stainless steel bushings are highly sought after for their durability and corrosion resistance. Two commonly used grades, 304 and 316, offer similar properties but differ in composition and performance:
Stainless Steel 304:
- Also known as A2 stainless steel.
- Contains 18% chromium and 8% nickel.
- Provides excellent corrosion resistance and good formability.
- Commonly used in construction, kitchenware, and medical equipment.
- Popular in the food and beverage industry due to its resistance to food-related corrosion.
Stainless Steel 316:
- Known as marine-grade stainless steel.
- Contains 16% chromium, 10% nickel, and 2% molybdenum, offering superior corrosion resistance, especially in harsh environments.
- Excellent for marine applications and environments exposed to saltwater, where pitting and crevice corrosion are a concern.
Key Differences:
- Composition: The addition of molybdenum in 316 enhances corrosion resistance, particularly in saltwater and acidic environments.
- Strength: Stainless Steel 316 is generally stronger than 304.
- Cost: 316 is more expensive due to its enhanced properties, but its superior corrosion resistance makes it a better choice for challenging environments.

What’s the difference between 304 and 316 stainless steel?
316 STAINLESS STEEL VS 304
316 has many similar chemical and mechanical properties to 304 stainless steel. To the naked eye, both metals look the same. However, the chemical composition of 316, which consists of 16% chromium, 10% nickel and 2% molybdenum, is the main difference between 304 and 316 stainless steel.
304 and 316 are both types of stainless steel, which are commonly used in a wide range of applications due to their excellent corrosion resistance and durability.
The main difference between 304 and 316 stainless steel is their chemical composition. 304 stainless steel contains 18% chromium and 8% nickel, while 316 stainless steel contains 16% chromium, 10% nickel, and 2% molybdenum.
The addition of molybdenum to 316 stainless steel gives it improved corrosion resistance, especially in environments with high levels of chloride, such as coastal regions and areas with saltwater exposure. This makes 316 stainless steel a popular choice for marine applications and other industries where corrosion resistance is critical.
In addition, 316 stainless steel has higher tensile strength and is more heat-resistant than 304 stainless steel, making it suitable for applications where high temperatures and/or high stresses are expected.
However, 304 stainless steel is generally less expensive than 316 stainless steel, making it a more cost-effective option in some applications where corrosion resistance is not the primary concern.
Overall, the choice between 304 and 316 stainless steel will depend on the specific application requirements, such as the environment, temperature, and stress levels.
