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...

SGO’s Reliability Evaluation System

 

How does SGO do a reliability evaluation?


Please check out the video of the process of making high quality products through various reliability tests!
SGO made an agreement for Industry-Academic MOU with Incheon Polytechnic University in July 2021 and has maintained a cooperative relationship by conducting research projects together.🔧







What is High Strength Brass?

High-Strength Brass is one of the representative base materials for Oilless Bearings. Zn, Al, Mn, Fe, etc. are added to 60/40 brass to increase strength and hardness, so it has excellent wear resistance even under high loads.
High-Strength Brass, commonly called Manganese Bronze, consists of the α+β structure. In particular, when high hardness and abrasion resistance are required, a single-phase type of β is also used.



KS CAC304 (DIN CuZn25Al5 / ASTM C86300) has high hardness and strength among high-strength brass materials, so it has high wear resistance even under high surface pressure. SGO has been developed and produced brass optimized for wear resistance characteristics of SP20 (hardness HBW 200), SP24 (hardness HBW 245), and SP28 (hardness HBW280) within the CAC304 standard range.



According to the request of the customers, SGO R&D can make prototype material and arrange a test by adjusting the mechanical properties and frictional properties through component composition and structure change, and please don’t hesitate to contact us, if you have any questions.

Bronze Casting Processes for Oil-less Bearings(3)

이미지
  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...

SGO THEDVELON Bearings

이미지
  SGO THEDVELON Bearings SGO THEDVELON THEDVELON  is a type of oilless bearing that  offsets the disadvantages of the sintered metal bearings by applying a heat treatment on a steel-backed material. It can be used for medium to high loads by supplementing the insufficient mechanical rigidity through diffusion-bonding the sintered layer and the back-steel, and the porosity of the sintered layer can also be varied. While it has an excellent abrasion resistance, it is highly price competitive owing to lower material costs compared to the conventional brass bearings. For any inquiries about   THEDVELON , please contact us by clicking the button below. INQUIRY

Types and Characteristics of Major Copper Alloys used for Oil-less Bearings

이미지
  Types and Characteristics of  Major Copper Alloys used for Oil-less Bearings SGO mainly manufactures Oil-less bearings using high-strength brass but used different bronzes per application. We will introduce the most used bronzes with characteristics and their uses. ※ KS D 6024 We have only introduced five materials that have been asked a lot, and there are many other copper alloy materials. You need to choose the base metal and solid lubricant depending on the working load, speed, and other working conditions of the bearings. SGO has a one-stop process from material to finished product, so if you need advice on Oil-less bearing, please don't hesitate to contact us. INQUIRY
