70% to passPacking extremely soft grease into a roller bearing will cause _______________.
Aexcessive channeling of the grease
Bhigh temperatures to develop as result of churning
Cemulsification of the thickener additive
Dgelling of the base oil
AI Explanation
The correct answer is B) high temperatures to develop as result of churning. Packing extremely soft grease into a roller bearing will cause the grease to be churned and agitated excessively, resulting in high temperatures developing within the bearing. This is because the soft grease requires more work to be distributed evenly, leading to increased friction and heat generation. The other answer choices are incorrect - excessive channeling, emulsification, and gelling are not the primary issues caused by packing too much soft grease into a roller bearing.
