UC206/P4 is a high-rigidity, low-play axial load applications. It features GCr15 cylindrical rollers (surface-hardened to HRC60+) that contact the precisely machined inner/outer raceways at 90°, specializing in unidirectional high axial loads. The "P4" ISO precision class ensures radial/axial clearance ≤0.015mm, meeting strict stability requirements for precision machinery. With a mounting lug on the outer ring, it simplifies assembly and guarantees coaxiality—ideal for heavy machinery, precision machine tools, and aerospace equipment.
