Q

Packing extremely soft grease into a roller bearing will cause __________.

🔍 Key Concepts

• Grease consistency and NLGI grade – what happens when grease is too soft for the application • Churning in bearings – how excess or too-soft grease behaves between rolling elements and races • Difference between chemical changes in grease (emulsification, gelling) vs. mechanical effects (heat, drag)

💭 Think About

• Think about what physically happens inside a roller bearing if it is overpacked with very soft grease while rotating at speed: does the grease stay in place, or get worked and stirred? • Which of the choices describes a condition that would most directly increase friction and energy loss inside the bearing? • Which options sound like changes to the grease’s chemistry or structure, and which sound like an operational consequence inside the bearing?

✅ Before You Answer

• Verify which condition is most associated with over-lubrication and excessive working of grease in high-speed bearings. • Check which answer involves heat generation due to mechanical action rather than a purely chemical change in the grease. • Eliminate any options that describe behavior more typical of stiff or stringy grease rather than extremely soft grease that is easily moved or stirred.
