Deep groove ball bearings Single-row deep groove ball bearings Deep groove ball bearings are available in a variety of sizes, and are the most popular of all rolling bearings. This type of bearing supports radial load and a certain degree of axial load in both directions simultaneously. ■ Shielded / sealed type • Simplifies sealing structure of applications. • Greasing is not necessary because bearings are pre-lubricated. • Table 1 on the next page lists major shielded and sealed bearing types and compares their performance. ■ With locating snap ring • Bearings with a locating snap ring can...

Boundary dimensions JTEKT [Notes] 1) Illustration (a) of the ZZ type shows the relatively small size bearing. 2) Illustration (d) of the 2RS type shows the relatively small size bearing. 3) The operating temperature range listed is for the standard type. It can be widened by using a different type of grease or sealing material. Consult with JTEKT for details. 1) The shielded/sealed type deep groove ball bearing and the deep groove ball bearing with a locating snap ring are designed for use with the inner ring rotating. Consult with JTEKT on use with the outer ring rotating. 2) When the...
