Grinder wear-resistant bimetallic Babbitt sliders, support pads, bottom pads, and side pads. The metallic characteristic of Babbitt alloy is that hard phase particles are uniformly distributed on a soft phase matrix. The soft phase matrix gives the alloy excellent embeddability, conformability, and anti-seizure properties. After running-in, the soft matrix becomes concave, and the hard particles protrude outward, forming micropores between sliding surfaces that serve as oil storage spaces and lubricant channels, creating a lubricating oil film layer that reduces friction and wear. The protruding hard particles support the journal, enhancing load-bearing capacity. Babbitt alloy, in addition to being used for manufacturing sliding bearings, is often applied as wire or powder sprayed onto steel, copper, or other substrates to create bimetallic bearing bushes and sleeves due to its soft texture and low strength. Babbitt alloys are divided into tin-based (tin-antimony bearing alloys) with a melting point of 230°C. To prevent component segregation, refine grain structure, and increase strength and hardness, small amounts of rare metals are often added. Henan Huachuang Babbitt alloy is a material used for casting bearing bushes, sleeves, liners, seals, wire rope pouring for slings, filling, and grinder support sliders.


Henan Huachuang Babbitt alloy, with advanced technology, excellent equipment, and strict technical testing, casts and manufactures support pads for metallurgical roll grinders; support pads for paper roll grinders; support pads for rubber roll grinders; and support pads for cold rolling and imported hot continuous rolling CNC roll grinders. The produced roll grinder support pads can withstand medium and heavy loads. They are made by casting tin-based Babbitt alloy ZHSnSb11-6 onto a steel base, with oil grooves machined on the alloy surface. Using hydrodynamic or hydrostatic support pads, the pad surface offers excellent embeddability, low friction coefficient, and superior conformability; high hardness, high load-bearing pressure, wear resistance, corrosion resistance, and long service life. They can process support pads for Waldrich roll grinders, Herkules roll grinder Babbitt support pads, and alloy support pads for center rests of grinders such as Shunyu, Huifeng, and Xianfeng models. Custom processing based on drawings and refurbishment of old parts can meet various requirements.
