70% to passIn a compression type automatic grease cup, the lubricant is forced into the bearing by _______________.
Aspring force
Ba pressure gun
Ca Zerk fitting
Dgravity flow
AI Explanation
A) spring force is the correct answer. In a compression type automatic grease cup, the lubricant is forced into the bearing by the force of a spring. The spring provides the necessary pressure to push the grease out of the cup and into the bearing, ensuring continuous lubrication. The other answer choices are incorrect because: B) a pressure gun is used for manual greasing, not an automatic grease cup; C) a Zerk fitting is the connection point for the grease gun, not the mechanism that forces the grease; and D) gravity flow would not provide the necessary pressure to effectively lubricate the bearing.
