When selecting bearings, many people may notice the label "C3" after the model number, but it is not clear what it specifically represents. Actually, "C3" here refers to the radial clearance level of the bearing.The so-called radial clearance refers to a certain gap reserved between the inner and

Imagine a car skidding on an icy road - although the tires are spinning, they cannot effectively propel the vehicle. A similar situation may also occur inside seemingly precise rolling bearings: when the pure rolling state that should have been maintained between the rolling elements and the

Have you ever thought about why the electric fan at home can run quietly for several years without needing to be serviced? Or is the food mixer both smooth and almost maintenance free to use? The answer is likely hidden in an inconspicuous yet incredibly intelligent small component - powder

In mechanical design, angular contact ball bearings are widely popular due to their ability to simultaneously withstand axial and radial loads, and are often mistaken for a "universal" solution. However, this kind of cognition can easily lead to selection bias, especially in application scenarios

SFC Bearing Officially Resumes Work In 2026On February 26,2026,after the Spring Festival holiday,all employees of SFC Bearing  returned to work with fully energy and positive attitude,officially launching the new year's work journey.Company leadres extended warm New Year greetings and best wishes

Among the numerous technical parameters of bearings, there is a often overlooked but far-reaching "invisible role" - clearance. Although it is not conspicuous, it directly determines whether the equipment can operate smoothly and for a long time. Choosing too big, the machine shakes like a sieve;

The single ball spline scheme allows the nut and screw to be replaced separately, which not only has high precision and reliability, but also provides greater flexibility in maintenance and material preparation. For systems that require long-term stable operation, it is a highly cost-effective

Proper installation and disassembly are key to ensuring the performance and lifespan of bearings. Improper operation can easily lead to damage to the raceway, deformation of the cage, and even early failure.Installation points:Clean environment: Ensure that the shaft, bearing seat, and tools are

In 2026, we will use precision bearings and linear

In the design of rolling bearings, although the cage does not directly bear the load, it plays a key role in the stability, service life, and applicable working conditions of operation. The selection of materials should comprehensively consider factors such as rotational speed, temperature,

Cast iron and cast steel are two commonly used materials for bearing seats, each with its own advantages and disadvantages, suitable for different occasions. Cast iron bearing seats are suitable for low-speed, light load, and situations that do not require high-precision operation due to their low

In mechanical design, although joint bearings are small in size, they bear the key tasks of complex loads and frequent swinging. Faced with a dazzling array of models such as GE, GAC, GX, etc., many engineers often feel confused: what exactly do these letters represent? In fact, each code

In the design of mechanical systems, the size of the shaft is usually determined first. The shaft diameter, shaft length, and the working load it bears will directly affect the overall layout of the equipment. After determining the specifications of the shaft, engineers need to choose suitable

The reliability of liquid dynamic pressure bearings in high-speed rotating machinery is directly related to the overall lifespan and operational safety of the machine. Its core lies in maintaining a stable lubricating oil film - once the oil film ruptures, direct contact with the metal surface will

In mechanical design, the "ultimate speed" of bearings is a often overlooked but crucial parameter. It refers to the maximum rotational speed at which a bearing can operate safely and stably under specific lubrication and installation conditions. Once the actual working speed exceeds this threshold

On November 28th, the 2025 Asia PTC Exhibition was held as scheduled in Shanghai. The four-day exhibition attracted foreign businessmen from all over the world. The exhibition exhibits cover 11 categories including hydraulic, pneumatic, sealing, gears, motors, transmission couplings, chain drives,

In the automotive cooling system, the water pump is a key component that ensures the normal operation of the engine, and its internal "core joint" - the shaft bearing, is quietly changing the traditional design logic. It is not a simple upgrade of ordinary bearings, but an innovative structure that

In the drive systems of high-speed rotating motors, precision running machine tools, and even new energy vehicles, a name repeatedly appears: GCr15. Why can this seemingly ordinary steel become the "standard configuration" for global bearing manufacturing? The material logic behind it is far more

The smaller the clearance, the better. Matching the working conditions is the keyThe internal clearance of rolling bearings directly affects the stability, temperature rise, and service life of equipment operation. Seemingly small 0.01mm gap changes may cause systematic failure at high temperatures

The 25th China Industrial Fair is about to open in Shanghai, with nine major exhibitions including CNC Machine Tool and Metal Processing Exhibition, Industrial Automation Exhibition, Robot Exhibition, Smart Energy Exhibition, New Generation Information Technology and Application Exhibition,

In modern households, washing machines hum and spin, refrigerators silently cool, air conditioners blow cool air, vacuum cleaners efficiently remove dust... Behind these seemingly ordinary household appliances lies a tiny yet crucial "joint" - the bearing. Although it is unobtrusive, it is an

Internationally, bearing size tolerances follow a strict standard system. The ISO 492 standard is adopted by most manufacturers worldwide, while China follows national standards such as GB/T 307.1-2019 for standardization. These standards not only classify different accuracy levels (such as P0, P6
