Correct option is D
A
footstep bearing is a type of bearing that
supports the axial (thrust) load of a vertical shaft. It is designed to
bear the weight of the shaft and any axial forces acting along its length.
Key Features of Footstep Bearings:
·
Supports Vertical Shafts:
· Used in applications where a shaft is positioned
vertically, such as in
water pumps and turbines.
·
Handles Thrust Loads:
· Designed specifically for
thrust (axial) loads, meaning it resists forces acting along the axis of the shaft.
·
Prevents Shaft End Wear:
· The bearing provides
support at the bottom of the shaft, reducing friction and wear.
