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.

The JRZC 23188 CA/W33 spherical roller bearing is engineered for heavy-duty industrial applications requiring high radial load capacity, strong impact resistance, and stable long-term performance. Built with a CA reinforced brass cage, this model ensures excellent mechanical strength and durability under continuous vibration, shock, and variable-load conditions. The W33 lubrication groove enhances grease flow and heat dissipation, reducing friction and extending operational life. It is widely applied in mining machinery, steel production systems, cement equipment, and large industrial gear transmission units.
Q1: What benefits does the CA brass cage offer for this model?
A1: It provides high rigidity and exceptional shock resistance, making it suitable for heavy-duty and high-impact applications.
Q2: How does the W33 lubrication groove improve bearing performance?
A2: It ensures better lubricant circulation, enhances cooling, and helps reduce wear and friction.
Q3: Is the 23188 CA/W33 suitable for continuous heavy-load use?
A3: Yes, it is specifically designed to operate reliably under long-term heavy radial loads.
Q4: Which industries commonly use this bearing type?
A4: Mining machinery, steel production, cement processing equipment, and large industrial gear systems.
