Because of their versatility, Single-row, Deep-groove Ball Bearings are the most popular of all the ball bearing types. NACHI Deep-groove Ball Bearings are available in a wide range of series defined by the JIS (ISO) standard dimension plan and are also made to meet specialized dimension and configuration requirements. Deep groove ball bearings are the most popular of all the ball bearing types because they are available in a wide variety of seal, shield and snap-ring arrangements. The bearing ring grooves are circular arcs made slightly larger than the radius of the ball. The balls make point contact with the raceways (elliptical contact when loaded). The inner ring shoulders are of equal height (as the outer ring shoulders). Deep groove ball bearings can sustain radial, axial or composite loads and because of simple design, this bearing type can be produced to provide both high running accuracy and high speed operation. Adopted NACHI original seal design to prevent contamination and grease leakage. Contains special grease for wider temperature ranges and longer life. The precision level of our bearing components has been enhanced to ensure smooth and quiet operation. Lower rotating torque by improving seal lips.
