Latest Patents

Oguri holds a patent for a "Combined ball bearing, main spindle device, and machine tool." This invention features a matched ball bearing that includes four or more rows of angular ball bearings axially aligned. The design incorporates two or more rows of angular ball bearings with contact angles in the same direction, arranged in a back-to-back combination. Each angular ball bearing has the same inner diameters, while those with contact angles in the same direction share the same outer diameters. Notably, the angular ball bearings with different contact angles have varying outer diameters. The design ensures that the angular ball bearing positioned at the axially outboard side has a larger ball diameter and a greater contact angle than the one positioned at the axially inboard side.
