  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(3)

  Bronze Casting Processes  for Oil-less Bearings (3) The last letter  covered Horizontal Continuous Casting, and we will introduce Metal Extrusion as the final episode of the casting process for oil-less bearings. Extrusion   Extrusion is a forming process that enables the continuous production of tubular or rod-shaped products with a uniform cross-section by extruding material through a mold. The material coming out of the mold is called the extrudate, and non-metals such as ceramics, plastics, and polymers are also suitable for extrusion.   UBE 2,750 ton Hot Extrusion Machine   Extrusion at room temperature is called cold extrusion, and extrusion by heating the billet above its recrystallization temperature to soften the metal is called hot extrusion. The extrusion process has a high initial cost and requires high compressive force, but it has many advantages technically and economically. Heated Billet Before Extrusion   Continuous casting allows th...
