The Correct Option is C
Solution and Explanation
Concept:
In sizing machines, beam press rollers are subjected to continuous mechanical load, friction, and slight impact during operation. The end caps of these rollers require a material that has good wear resistance, toughness, and self-lubricating properties to ensure long service life and smooth rotation.
Nylon (polyamide) is widely used for such applications due to its excellent mechanical strength and low friction characteristics.
Step 1: Understand functional requirement.
End caps must withstand:
• Mechanical stress
• Continuous rotation
• Frictional wear
Step 2: Evaluate material properties.
• PET → good polymer but less wear resistance here
• Polyethylene → softer, low strength
• CFRP → high strength but not used as bearing cap
• Nylon → high wear resistance and toughness
Step 3: Select correct material.
\[ \text{Nylon is preferred for bearing and end-cap applications} \]
Step 4: Final answer selection.
Thus, \[ \boxed{\text{Nylon}} \] Therefore, \[ \boxed{\text{Option (C) is correct.}} \]
