Subtopic: Measurement of force, stress, torque, speed, displacement and acceleration on machine elements – shafts, couplings, keys, bearings and knuckle joints
Question Statement:
Tapered roller bearings are specifically suited for tractor wheel hubs because:
Options:
(A) They can support heavy combined radial and thrust (axial) loads simultaneously
(B) They can operate with zero lubrication
(C) They are flexible across misalignment angles up to $30^\circ$
(D) They eliminate rolling resistance completely
Answer Key:
A
Step-by-Step Solution & Explanation
Tapered roller bearings feature conical rollers and raceways capable of carrying substantial simultaneous radial and axial shock loads in agricultural wheel assemblies.
