McMaster 1378N72 Crossed-Roller Bearing, Thin-Profile, Sealed, for 80 mm Shaft Diameter

For a more compact machine, these bearings have thinner inner and outer rings than high-load crossed-roller bearings. Route hydraulic lines, electrical wiring, and other components through the inside of the bearing. The rollers face in alternating directions to allow for rigid, accurate motion under any combination of radial, thrust, and moment (twisting) loads. Use in applications where highly accurate motion is necessary, such as machine tools and industrial robots.Sealed Bearing — Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.
