Double Row Cylindrical Roller Bearing CPM2518 50×72.33×39mm Without Outer Ring for Planetary Gearbox

Double Row Cylindrical Roller Bearing CPM2518 50×72.33×39mm Without Outer Ring for Planetary Gearbox 

The CPM2518 Cylindrical Roller Bearing is an engineered, high-capacity component designed without an outer ring, allowing its rollers to run directly on the housing bore. This compact design delivers maximum radial load capacity and rigidity, making it an ideal choice for compact drive mechanisms. It is widely used in high-torque reducer gearboxes where radial space is strictly limited.

• Outer-ring-free architecture maximizes space utilization and stiffness within a compact footprint.
• Double-row full complement design incorporates the maximum number of rollers to achieve extreme radial load carrying capabilities.
• High rigidity and stability provide stable operation and reliable planetary gear alignment under variable torque conditions.
• Heavy shock resistance easily handles sudden moment loads and demanding industrial impact forces.
