NTN 6018 LLB Deep Groove Ball Bearing

The NTN 6018 LLB is a deep groove ball bearing with inner diameter 90 mm, outer diameter 140 mm and width 24 mm. It suits electricians and maintenance engineers who need a sealed rolling element for motor shafts, gearboxes or conveyor rollers. The LLB suffix indicates double lip seals that retain grease and exclude contaminants.

Sustained load behaviour

Under continuous rotation the bearing runs on a deep groove raceway that distributes radial and moderate axial forces evenly across the balls. The sealed design limits lubricant loss during extended duty cycles, reducing the need for relubrication intervals. Operators should verify shaft and housing tolerances to maintain the intended internal clearance.

Questions about this item

How much heat does the 6018 LLB generate when running continuously in a motor?

The 6018 LLB deep groove ball bearing uses low-friction steel balls and dual LLB seals to minimise heat build-up during all-day operation in electric motors or gearboxes.

What shaft and housing sizes are needed to mount the 90x140x24mm bearing?

You need a 90 mm shaft and a 140 mm housing bore; the 24 mm width fits standard 6018-series mounting shoulders and snap-ring grooves.
