Product Description

With viiplus's self-lubricating bearings, you will love the low-noise, maintenance-free parts experience of self-lubricating bearings.

 
VSB-JDB-4 Graphite grey cast iron bearing cast iron inlaid bearing is a new product based on HT250 embedded solid lubricant, which is a typical material saving product.If the pressure < 14.5n /mm2 or mechanical performance requirements, can be used as a substitute for chb-jdb-2 material.Can greatly reduce the cost, meet the use requirements.For example, the mold guide column, injection molding machine mold frame and other fields can be used.

Grey cast iron has good casting performance, good vibration absorption, good wear resistance, good cutting performance and low notch sensitivity.
The influence factors of the properties of grey cast iron the influence of chemical composition.Production is mainly controlled by the mass fraction of carbon and silicon.With low carbon and silicon content, the cast iron is prone to white microstructure, and its mechanical properties and casting properties are very low.
When the mass fraction of carbon and silicon is too high, the graphite sheet is too much and too thick, and even graphite floats on the surface of molten iron, which reduces the performance and quality of the casting.
Therefore, the content of carbon and silicon in gray cast iron is generally controlled at 2%~ 4%C.1.0% ~ 2.0% Si;0.5% ~ 1.4% Mn.
Influence of cooling speed: in a certain casting process, the cooling speed of the casting has a great impact on the degree of graphite.With the increase of the wall thickness, the cooling rate of the castings slows down and the carbon atoms have sufficient diffusion time, which is conducive to the graphitization process and the gray-iron structure can be easily formed at room temperature.However, thin-walled parts in the cooling process of cooling too fast, easy to form a white iron.
