Product Description

This category covers NSK ball bearing units — products combining the bearing itself with a housing as an integrated unit. The spherical outer bearing race mates with a matching spherical housing seat, self-aligning to absorb minor installation misalignment without the need for precision machining, greatly reducing installation time. Housing styles commonly include pillow block and flange types; the inner ring is typically locked to the shaft with set screws, making maintenance and replacement convenient. Commonly used to support general drive shafts in conveyors, agricultural machinery and packaging equipment.

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.
