23244 CC/W33
JRZC uses high-purity vacuum-degassed bearing steel as raw material to ensure the quality of CC-type spherical roller bearings from the very beginning. The rings and rollers are treated with Aichelin salt bath heat treatment to guarantee consistent hardness and stable performance. The hardness difference between the bearing rings and rollers is less than 1 HRC, which is 30% stricter than the standard requirement of GB/T 34891-2017.
CC cage ensures low friction and stable operation.
C3 clearance accommodates heat expansion under heavy load.
W33 lubrication groove supports effective cooling and long lubrication intervals.
High fatigue-resistant steel improves durability in harsh environments.

How JRZC CC Series Spherical Roller Bearing Creates Value for Customers
1. Solve "Difficult Installation & Misalignment" — Excellent Self-Aligning Capability
In large equipment such as mining and metallurgy machinery, perfect alignment between the shaft and bearing housing is often difficult to achieve, and shaft deflection during operation is unavoidable.
Solution: JRZC CC Series spherical roller bearings feature a spherical outer ring raceway design, providing automatic self-aligning capability.
Customer Benefits: Even when the shaft bends under load or there are angular installation errors, the bearing automatically compensates, effectively avoiding edge stress concentration. This prevents premature bearing failure, significantly reduces installation precision requirements, and lowers maintenance difficulty.
2. Tackle "Overload & Shock Loads" — Ultra-High Load Carrying Capacity
Equipment like crushers and vibrating screens often endure intense shock loads, which can easily cause fatigue spalling of internal bearing components.
Solution: The CC Series design adopts symmetrical spherical rollers and optimized raceway profiles. Combined with JRZC's strict heat treatment process, the contact stress distribution between rollers and raceways is more uniform.
Customer Benefits: Compared to conventional bearings, the JRZC CC Series significantly improves radial and axial load carrying capacity. Within the same dimensional envelope, it withstands higher loads, effectively extending equipment service life under heavy-duty conditions.
3. Reduce "Friction & Energy Consumption" Costs — Optimized Cage Design
With rising electricity costs, drive system energy consumption has become a key focus for factories. High friction not only wastes electricity but also leads to excessive bearing temperature rise and lubricant degradation.
Solution: JRZC CC Series comes standard with stamped steel cages (brass or nylon cages available for certain sizes). These cages are lightweight and high-strength, reducing sliding friction between rollers and the cage.
Customer Benefits: Significantly lower operating temperature and frictional torque. Even at high speeds, the bearing runs "cool," helping your drive system achieve energy savings and reduced consumption, while extending lubrication intervals.
4. Resist "Harsh Environments" — Enhanced Lubrication & Protection
In the paper, cement, or wind power industries, water, dust, and high temperatures are the top enemies of bearings.
Solution: JRZC offers W33 oil groove and hole design (lubrication groove and holes on the outer ring) and optional sealing solutions.
Customer Benefits: Maintenance personnel can easily perform relubrication, ensuring fresh grease flows smoothly into the raceway and flushes out contaminants. This allows the bearing to maintain excellent performance even in extremely contaminated or humid environments, significantly improving wear resistance.
