Product Description

The 52230X is an NSK double-direction thrust ball bearing (flat seat type): 150 mm bore, 215 mm outer diameter, 89 mm overall height. Basic dynamic load rating Ca is 238000 N and basic static load rating C0a is 735000 N (NSK official catalog CAT. No. E1103d). Double-direction thrust ball bearings carry pure axial load in both directions with no radial load capacity; shaft/housing washer orientation must not be reversed during installation. From the same NSK thrust ball bearing table as Nahshon's existing 51xxx single-direction series, commonly used in screw drives, valves and precision positioning mechanisms requiring bidirectional axial location. A matching aligning-seat (54 series) and aligning-seat-washer (54 series U) variant is also available for this size.

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.

Is 52230X in stock in Taiwan? What is the lead time?
