Dimensions and load ratings per the NTN catalogue (metric and inch bores). The catalogue number adds suffixes to the base number shown here; confirm the exact version and brand with us before ordering. Cr and Cor are basic dynamic and static load ratings in newtons.
Inch Shaft Sizes
The UEL3 insert bearing is also supplied with inch bores. The number carries a suffix for the shaft size (for example -104 is 1-1/4 inch). Outside dimensions and load ratings match the metric size in the table above; the set screw thread is the inch (UNF) size shown.
