Chrome steel balls, also called bearing steel balls, are the most widely used bearing balls in the ball and roller bearing industry and for a variety of automobile applications. The material of our chrome steel balls uses high chromium bearing steel GCr15 and GCr15SiMn. With high-quality material, MZ chrome steel balls offer prefect precision, outstanding surface roughness, proper hardness, superior wear resistance and high load bearing capacity. Our steel ball factory supply chrome steel balls in size range 0.5 mm – 82.55 mm, precision grade G 10 – G200. Especially 25.4 mm – 82.55 mm big size high precision chrome steel balls are our principal products. MZ chrome steel balls make your bearing roll smoother.
