The construction of this type ball bearing is similar to the adjacent, BACK-TO-BACK mounting of two Single-row Angular Contact ball bearings. Because fewer balls can be inserted per row compared to Single-row Angular Contact ball bearings, a Double-row Angular Contact ball bearing will have less load capacity than an equivalent size/series BACK-TO-BACK set of two Single-row Angular Contact ball bearings. This bearing type can sustain radial, moment and bi-directional axial loads.
I wanted to delete my Oil Mist system on my Duhnam Collet closer for my GT-27 lathe. So I ordered these as an upgrade and so far it's running just fine without the oil mist.
