Because of their versatility, Single-row, Deep Groove Ball Bearings are the most popular of all 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. NACHI Deep Groove Ball Bearings are manufactured in both standard precision

grade (ISO Grade 0 - ABEC Grade 1) as well as in high-precision grades.Table 1 shows common, standard configurations of Single-row Deep Groove Ball Bearings.Table 2 next page shows a comparison of general characteristics of seal and shield designs for Single-row, Deep Groove Ball bearings.

Attention(1) Deep-groove Ball Bearings can sustain radial, axial or composite loads.However when excessive axial load is applied, please consult with NACHI.

(2) Because sealed or shielded bearings are designed for inner ring rotating applications, the filled grease may leak when they are used with a high speed outer ring rotating condition.In such a case, please contact NACHI.

(3) When bearings with contact rubber seals are used in a severe operating condition such as high speed or high temperature, the filled grease may leak.In such a case, a design change or another kind of grease is required.

(4) When a bearing is mounted on a shaft (into a housing), force should only be applied to the side face of the inner (outer) ring.

(5) The sealed or shielded bearings should not be washed or heated before mounting.

(6) It should be noted that mounting errors such as misalignment of the bearing rings cause an appreciable increase in noise level.

(7) The bearings must always be subjected to a minimum load to prevent sliding movements occurring between the balls and the raceways.
