Product Description

The 30215 is an NSK tapered roller bearing from the 30215 series: 75 mm bore, 130 mm outer diameter, 27.25 mm width. Tapered roller bearings use a tapered inner ring, rollers and outer raceway so a single bearing carries combined radial load and axial load in one direction; inner and outer rings are separable, giving flexible mounting and clearance adjustment. Basic dynamic load rating Cr is 176 kN and basic static load rating C0r is 182 kN (NSK official catalog CAT. No. E1103d; current-generation equivalent HR30215J, Cr/C0r figures above are taken from that current design).

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.
