Product Description

The point-contact raceway/ball design gives a simple, low-friction structure suitable for high-speed operation, carrying radial load plus moderate bidirectional axial load — the most widely used bearing type. Available with open, single/double steel shields (Z/ZZ), and contact/non-contact rubber seals (V/VV/DDU) for various sealing needs, covering sizes from miniature to medium-large, commonly used in motors, gearboxes, pumps, fans and general transmission 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.
