Bearing-grade grinding wheels since 2003
Yangzhong Hongda Bearing Special Abrasives Co., Ltd. is located in Xinba Town, Yangzhong — known in China as the hometown of abrasives. We focus on precision wheels and stones for the bearing and transmission industries.
Twenty years of focus
Company founded, making superfinishing stones.
Moved to a 2,000 m² plant and began making high-speed wheels for the bearing industry.
Moved to 4,000 m² and introduced vitrified CBN wheels — up to 20× the grinding efficiency of alumina wheels.
Developed sol-gel (SG) alumina and low-temperature sintering, extending into gears, compressors, rails, screws, crankshafts and engines.
New 6,000 m² climate-controlled workshop; total plant 10,000 m² with automatic CNC equipment.
