Product Description

The 24180CAMK30E4 is an NSK spherical roller bearing, series 241, tapered bore (K type): 400 mm bore, 650 mm outer diameter, 250 mm width. Basic dynamic load rating Cr is 4950000 N and basic static load rating C0r is 10100000 N (NSK official catalog CAT. No. E1103d). The double-row roller and spherical outer raceway design automatically compensates for misalignment and shaft deflection while carrying high radial load plus bidirectional axial load. Commonly used in long-shaft drives, gearboxes, wind turbines, paper machines and heavy-duty industrial machinery.

FAQ

What's the difference between the Z, ZZ and DDU suffixes?

Z means a single-side steel shield, ZZ means steel shields on both sides, and DDU means contact rubber seals on both sides. Shields suit general environments and high speeds; rubber seals give better dust and water protection with slightly higher friction torque — choose based on your dust exposure and lubrication method.

When should I choose C3 clearance instead of standard clearance?

For motors or other applications with noticeable temperature rise, or high-speed operation, the inner ring expands from heat and reduces the clearance — choose C3 in that case. Standard clearance is fine for general room-temperature, low-speed use. See Nahshon's technical resources for a clearance selection guide.
