Product Description

The 5202 is an NSK double-row angular contact ball bearing from the 5202 series: 15 mm bore, 35 mm outer diameter, 15.9 mm width, open type. Basic dynamic load rating Cr is 12.9 kN and basic static load rating C0r is 7.05 kN (NSK official catalog CAT. No. E1103d). Inner and outer rings are each integrated into one piece, equivalent to a back-to-back pair of single-row angular contact bearings — a single unit carries bidirectional axial load, radial load and moment loading, common in machine-tool spindles, printing machinery and pumps as a fixed-end bearing.

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 5202 in stock in Taiwan? What is the lead time?

Nahshon is the NSK distributor in Taiwan and keeps stock of some commonly used items. Add 5202 to your inquiry list or give us a call, and we'll confirm stock, lead time and quote.
