7320BW

Angular Contact Ball Bearing

NSK Distributor Taiwan

Product Features

  • The angled raceway/ball contact design carries radial load plus axial load in one direction; two or more bearings are typically paired (DB/DF/DT arrangement) for bidirectional load
  • Available in 15°, 25°, 30° and 40° contact-angle series — larger contact angle gives higher axial load capacity
  • Precision grades suit machine tool spindles and precision instrumentation for high-speed rotation; standard grades are common in gearboxes and pump drives
  • Nahshon is NSK's distributor in Taiwan — add the part number to your inquiry list and we will confirm the current spec and quote with the factory

Product Description

This category covers NSK angular contact ball bearings. The angled raceway/ball contact design carries radial load plus axial load in one direction; in practice two or more bearings are typically paired (DB/DF/DT arrangement) for bidirectional load. Available in 15°, 25°, 30° and 40° contact-angle series — larger contact angle gives higher axial load capacity. Precision grades suit machine tool spindles, semiconductor equipment and precision instrumentation for high-speed rotation; standard grades are common in gearboxes, pumps and general drive mechanisms.

For current spec and catalog cross-reference, please inquire: Nahshon is NSK's distributor in Taiwan with full part-number lookup and sourcing support — add the part number to your inquiry list and we will confirm the current code, spec and quote with the factory; sourcing support is also available for discontinued models.

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 7320BW 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 7320BW to your inquiry list or give us a call, and we'll confirm stock, lead time and quote.
