Product Description

The 692ZZ is an NSK miniature ball bearing (double-shielded type (ZZ)): 2 mm bore, 6 mm outer diameter. Basic dynamic load rating Cr is 330 N and basic static load rating C0r is 98 N (NSK official catalog CAT. No. E126h). Miniature ball bearings cover a 1–9 mm bore range, sharing the same construction as standard deep groove ball bearings — carrying radial load plus moderate bidirectional axial load. Widely used in optical instruments, medical devices, OA equipment, small motors and precision small-scale mechanisms.

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 692ZZ 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 692ZZ to your inquiry list or give us a call, and we'll confirm stock, lead time and quote.
