NTN 6318 ZZ Deep Groove Ball Bearings

The NTN 6318 ZZ deep groove ball bearings measure 90x190x43mm and suit electricians and maintenance technicians who need reliable rolling-element components for motor repair or equipment servicing. Supplied as a single pack in a red finish, they are new and ready for immediate installation.

Replacing worn or noisy bearings

These units replace damaged 6318-series bearings in electric motors, pumps and gearboxes where radial and axial loads are present. The jump is worth it when vibration, heat or play in the shaft indicates the original bearing has reached the end of its service life.

Limits of the 6318 series

The 6318 ZZ designation means metal shields on both sides, so the bearing is not designed for relubrication and must be replaced once the factory grease degrades. Speed and load capacity are defined by the 90x190x43mm envelope, so applications exceeding those parameters require a different series.

Questions about this item

What shaft diameter and housing bore does the 90x190x43mm bearing fit?

The 90 mm inner diameter seats on a 90 mm shaft, and the 190 mm outer diameter presses into a 190 mm housing bore with the 43 mm width matching the shoulder spacing.

How do I press the NTN 6318 ZZ onto the shaft without damaging the seals?

Apply even force only to the inner ring using a sleeve or press tool that contacts the 90 mm bore; never hammer the outer ring or the red shields.

When should the NTN 6318 ZZ be replaced in continuous service?

Replace at the first sign of vibration, noise or seal wear; the factory rates the parts for three years and labour coverage for one year.
