Bearing Combinations

Arrangement types of angular contact ball bearing combinations
1. DB combination (back to back): The large distance between the effective load centers results in higher rigidity at the moment load. However if accuracy of housing is not enough, it may produce damage e.g. flaking at a earlier stage due to the increased internal load. Preload is determined by torque when the user fastens the lock-nut.
2. DF combination (face to face): The small distance between effective load centers limits bearing capacity to sustain moment load, however it performs at a better level to absorb the margin of assembly error. Preload is determined at maker’s assembly of bearing cover, thus this way allows easier self-management for users.
Standard arrangement type of Sung-il products is DF combination.
- In any case DB combination type is requested, please contact Sung-il Customer Service team for further assistance.
