23144 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 provides smooth and low-friction operation.
W33 lubrication groove enhances cooling and relubrication efficiency.
High-load design supports continuous heavy-duty operation.
Durable steel improves fatigue resistance under harsh conditions.
