In the world of precision bearing grinding, victory is often determined within mere microns. When tiny grinding chips (grit) are not promptly and thoroughly removed, they linger between the grinding wheel and the workpiece, or adhere to the workpiece surface — triggering a chain of issues that can compromise both accuracy and efficiency.

Nanjing Kerun Industrial Media Co., Ltd. (hereinafter “Kerun”) has responded with precision insight, launching a solution purpose‑built for high‑precision grinding — the fully synthetic metalworking fluid KR‑C9030G. Beyond delivering exceptional lubrication performance, it acts as a “clean‑guard” to protect machining accuracy, making it especially suitable for applications demanding superior surface finish and dimensional precision, such as precision grinding of bearing inner/outer rings and rollers.
01: Spotless Clean — Rapid Grit Release, No Secondary Damage
KR‑C9030G offers outstanding chip‑settling and cleaning performance. It quickly penetrates the fine grinding debris (grit) generated during processing and, aided by a powerful coolant‑flow system, thoroughly removes it from the machining zone. This prevents grit from remaining on the workpiece surface or accumulating in the wheel gaps, fundamentally eliminating the risk of grit‑induced scratches. The result is a direct improvement in the bearing’s finished appearance — from flawless surfaces to a higher degree of smoothness.

02: Smooth and Unhindered — Exceptional Lubrication for Dimensional Precision
The hardness of bearing materials and the precision required in grinding place exceptionally high demands on a metalworking fluid’s lubrication performance. KR‑C9030G is formulated with high‑performance extreme‑pressure lubrication additives that form a resilient lubricating film at high‑pressure, high‑speed grinding points. This reduces grinding resistance, effectively controls temperature rise, and extends the service life of the grinding wheel.

Customer Testimonial
“Previously, we were constantly troubled by scratches on bearing rollers after grinding and grit clogging in the grinding wheel. Since adopting Kerun’s fully synthetic metalworking fluid KR‑C9030G, these issues have been effectively resolved — and the overall benefits have been remarkable: higher machining precision, reduced product allowance, greatly improved grinding efficiency, and better control over grinding wheel consumption. Most importantly, our overall production costs have been optimized as a result.”
