CYLINDRICAL ROLLER BEARINGS — N2300EM SERIES (WIDE, HIGH RADIAL LOAD)
Series Overview
The N2300EM series are cylindrical roller bearings in the 2300 wide dimension class, covering bore diameters from 15 mm to 60 mm. The 2300 class has a significantly wider B-dimension than the 2200 class at any given bore and outer diameter, providing the highest radial load capacity within standard CRB families.
All models use brass cages (EM suffix). Available cage configurations vary by model. Interchangeable with SKF, FAG, NSK and Koyo N2300EM equivalents. Supplied by GBC, MOQ 100 pieces.
Key Design Features
Highest radial capacity in standard CRB families
Wide 2300 cross-section reaches 168 kN dynamic and 188 kN static at d 60 mm.
EM brass cage throughout the series
All N2300EM models use precision-machined brass cages, providing dimensional stability at elevated temperatures.
Wide B-dimension for load distribution and stiffness
Greatest axial width in the standard CRB range distributes load over the longest possible roller contact length.
Separable rings for staged installation
Inner and outer rings separate independently for staged assembly — practical in larger bore sizes.
Boundary dimensions: d bore · D outer diameter · T / B width (mm)

Typical Applications
The N2300EM series is the top-of-range radial load choice within standard cylindrical roller bearing families.
Heavy machine tool spindles
Grinding and turning centre spindles requiring the highest radial load capacity in a given bore class
Large heavy-duty gearboxes
Gearbox shaft bearings where 2200EM capacity is marginal
Steel and roll mill applications
Roll neck bearings for sheet and bar mills, calender roll shafts
High-output industrial motors
Large motor shaft support under maximum continuous radial loading
