NTN 6218LLB deep groove ball bearing

This NTN 6218LLB deep groove ball bearing measures 90x160x30mm and fits rotating shafts in motor assemblies and power-tool gearboxes. The double-sealed LLB design keeps lubricant in and contaminants out for reliable operation in dusty workshop conditions. Electricians and maintenance technicians use it to restore smooth rotation in worn equipment.

Replaces worn original bearings in compatible

Install this bearing when the existing unit shows excess play, noise or heat during operation. The 90x160x30mm dimensions must match the shaft and housing seats exactly; otherwise the fit will be incorrect. It is not suited for applications needing angular-contact load capacity or a different bore diameter.

Questions about this item

What shaft diameter fits the 90 mm bore of the 6218LLB bearing?

The 6218LLB has a 90 mm inner diameter, so it fits a 90 mm shaft with the appropriate tolerance.

How do I press the 6218LLB into a 160 mm housing without damaging the seals?

Apply even pressure on the outer ring only, using a sleeve that contacts the 160 mm outer diameter, to avoid pushing on the LLB seals.
