🔍 Key Concepts

• Packing ring wear patterns and what they indicate about alignment or movement • How bearing condition affects shaft alignment and contact surfaces • Difference between issues caused by gland adjustment versus rotating components

💭 Think About

• Think about which choice would cause the shaft or rotating part to run out of true and press the packing unevenly against the inner circumference. • Which option would make the packing ring rub harder in one localized spot instead of evenly all around? • Which condition would most directly change the alignment or stability of the rotating parts that contact the packing?

✅ Before You Answer

• Verify which condition would cause misalignment or wobble of the rotating element. • Check which choices mainly affect pressure/suction rather than physical contact or alignment. • Confirm which option would likely produce localized (not uniform) wear on the packing ring.
