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 23088 CAK/C3W33 spherical roller bearing is engineered for heavy-duty applications requiring high radial load capacity, excellent impact resistance, and stable performance under continuous vibration and elevated temperatures. Featuring a CAK reinforced brass cage and a C3 internal clearance, this model offers superior tolerance for thermal expansion and ensures smooth operation under fluctuating or high-load conditions. The W33 lubrication groove enhances grease circulation, optimizes cooling efficiency, and reduces friction, extending the service life of the bearing. It is widely used in mining machinery, steel production systems, cement plants, and large industrial gearbox assemblies.
Q1: What benefits does the CAK cage provide in this model?
A1: The CAK cage delivers reinforced rigidity and stability, making it suitable for heavy impact and misalignment conditions.
Q2: Why is C3 internal clearance chosen for this bearing?
A2: C3 provides additional space for heat expansion, preventing excessive friction during high loads and elevated temperatures.
Q3: How does the W33 lubrication groove enhance performance?
A3: It ensures efficient lubricant distribution, improves cooling, and reduces operating friction to extend service life.
Q4: What industries commonly use the 23088 CAK/C3W33?
A4: It is widely used in mining operations, steel processing, cement manufacturing, and large industrial drive units.
