23092 CA/C3W33
High-efficiency impact crushers are mainly used in secondary and tertiary fine crushing processes, featuring high crushing performance, efficiency, and energy savings. JRZC designs CA-type spherical roller bearings specifically to support these crushers. JRZC uses high-purity vacuum-degassed bearing steel as raw material to ensure bearing quality from the very beginning. The use of Michelin salt bath heat treatment for the rings and rollers contributes to stable quality and performance. The hardness difference between the bearing rings and rollers is less than 1 HRC — a requirement that is 30% stricter than the GB/T 34891-2017 standard.
