Thrust Ball Bearings 10mm x 18mm x 5.5mm one Thrust Ball Bearings
One Thrust Ball bearings, Thrust bearings are known to high axial loads, Bearings are made of Chrome Steel, inner diameter is 10mm, outer diameter is 18mm and width is 5.5mm.
The fluting looks ruff in the races but will control low RPM without heat problems. They don't hold load pressure perpendicular to the shaft they are primarily thrust control. Can't beat the price for it's intended use. Ruff fluting is to prevent bearing skid when the bearings get dirty and loose also a thrust bearing must have very little contact area with the race or it will destroy itself.
