The 6018-ZZ is a precision-engineered, light-series ball bearing designed specifically for applications requiring a large shaft diameter within restricted radial spaces. Equipped with twin pressed-steel shields (ZZ), this bearing creates a non-contact barrier that safeguards the internal rolling elements from industrial particulates while permanently retaining the factory-filled lubricant. With a 90mm bore, a 140mm outer diameter, and a slim 24mm profile, the 6018-ZZ delivers reliable rotational efficiency for heavy-duty electric motors, industrial blowers, and precision gear units where housing dimensions are tightly constrained.
