Deep Groove Ball Bearing 6818 LLU
This NTN 6818 LLU deep groove ball bearing fits shafts and housings that require a 90 mm inner diameter and a 115 mm outer diameter with a 13 mm width. It is supplied as a single unit in a box and is intended for electricians and maintenance technicians who need a direct replacement for worn bearings in motor assemblies or test equipment.
Replaces worn 6818 series bearings
The bearing upgrades equipment that currently runs on a damaged or noisy 6818 unit showing excessive play or heat. The jump is worth it when vibration readings rise, lubricant leakage appears, or scheduled overhaul intervals call for fresh LLU-sealed components before the next service window.
Runs sealed under continuous rotation
Dual LLU contact seals keep grease in and contaminants out during prolonged operation in electrician tools and test rigs. The deep groove geometry handles combined radial and axial loads steadily, so temperature stabilises without the spikes seen in open bearings that lose lubrication mid-shift.
