What is SDX Bearing? (2)

  What is SDX Bearing? (2) ✅ FAQ 1. What is the difference between SDX and dry-bearing SDU? SDU is a dry-bearing that can operate without lubrication and is resistant to most solvents and industrial fluids. On the other hand, SDX bearings are pre-lubricated by applying grease during assembly and are generally used in agricultural machinery, hydraulic machinery, and automobiles. 2. What is the plating material for the outer diameter? It is usually tin-plated with a thickness of about 0.002 mm, and copper plating is available upon request. 3. Is there any difference in performance depending on the POM colors? There is no difference in the performance and price from the standard product (yellow POM + tin plating). Other colors besides yellow POM can be made to order. SDX bearings with PEEK are recommended for high-temperature environments such as high-pressure gear pumps, water injection pumps, paint spraying, etc. 4. What material is recommended for the shaft? It can be used with all...

Bronze Casting Processes for Oil-less Bearings (2)

  Bronze Casting Processes  for Oil-less Bearings (2) Today, we will introduce horizontal continuous casting.  Horizontal Continuous Casting   One of the most sophisticated methods of casting copper alloys is continuous casting. This metal casting method is most effective when large quantities of standardized semi-finished products are to be produced. There are two types of horizontal and vertical continuous casting, and we will introduce horizontal continuous casting.   Horizontal Continuous Casting   This method allows greater control over the process through automation.A uniform semi-finished metal product can be obtained through continuous metal supply, crystallization, and removal of foreign matter. Crystallization speed can be adjusted by cooling with the flow and velocity of distilled water. Depending on the speed of horizontal continuous casting, solidification of the material (basically along the length of the casting) can be achieved, and dense ba...

Bronze Casting Processes for Oil-less Bearings (1)

  Bronze Casting Processes  for Oil-less Bearings (1) Following the last letter about the main bronze materials for the oil-less bearings, today’s letter is about two bronze casting processes and their characteristics.   ※ Sand-Casting ※ Sand Cast Bushings 1. Sand Casting   Sand casting is a casting process characterized by using sand as the mold material, which can be used for both ferrous and non-ferrous metals. It is widely used in the mass production of industrial units such as automotive metal casting parts such as engine blocks, cylinder heads, crankshafts, etc.   2.  Oilless Bearings     Centrifugal casting is a process of manufacturing cylindrical parts using centrifugal force. This type of metal casting uses a preheated rotating die into which molten metal is poured. Centrifugal force helps distribute molten metal within the die at high speed.   The molten metal flows in and is distributed in the mold at high speed to prevent poor fl...
