Product Description
The ZYS cylindrical roller bearings are designed for high performance and durability, available in two main structural series: single-row bearings (N10) and double-row bearings (NN30). The inner ring features a shoulder, while the outer ring is separable, making it easy to install and maintain. For double-row cylindrical roller bearings that use oil lubrication, an axial oil groove and three symmetric oil holes are integrated into the outer ring, marked as W33, ensuring efficient lubrication and extended service life.
