Precision deep-groove bearing for motor shafts
The ZIBOO NTN 6218 ZZ is a single-row deep-groove ball bearing built for electric-motor repair and industrial maintenance. Its 90 mm bore, 160 mm outer diameter and 30 mm width suit standard shaft sizes in pumps, fans and gearboxes. Supplied as one unit in a box, it arrives new and ready for immediate installation.
Sustained operation with sealed lubrication
Double metal shields keep factory grease inside while excluding dust and coolant during continuous duty. The deep-groove geometry handles combined radial and axial loads without the temperature spikes seen in open bearings under long runs. Steel cages maintain ball spacing at constant speed, reducing vibration that would otherwise shorten service intervals.
Shielded steel construction simplifies mounting
The 6218 ZZ fits standard housings and snap-ring grooves, so no special adapters are required. Metal shields withstand higher housing temperatures than rubber seals, making the bearing suitable for environments where heat soak is normal. Red finish provides quick visual identification in mixed-part bins. Buyers needing integrated snap rings or ceramic balls should select a different part number.

Questions about this item
How much heat does the NTN 6218 ZZ bearing generate during continuous all-day operation?
The sealed ZZ design keeps lubricant inside, so friction and heat stay low during extended running.
What shaft and housing dimensions must already be in place for the 90x160x30mm bearing to fit?
A 90 mm shaft diameter, 160 mm housing bore and 30 mm width are required for proper installation.
Will the 6218 ZZ bearing work alongside older open-type bearings on the same shaft?
Yes, the same 90x160x30mm envelope allows mixed ZZ and open bearings, but sealing differs.
