Ball Operation Vertical
Check Valve - an overview | ScienceDirect Topics
A ball check valve is a type of check valve in which the movable part is a spherical ball, as illustrated in Figure 4.13. Ball check valves are used in spray devices, dispenser spigots, manual and other pumps, and refillable dispensing syringes. Ball check valves may sometimes use a free-floating or spring-loaded ball.

Operation and Maintenance of Vertical Motors | Pumps & …
Angular contact ball bearings are the most common thrust bearings in vertical motors. A single bearing is used for normal thrust loads. Two bearings can be used in tandem for 175 percent of normal thrust (see Figure 2), and three bearings can be stacked for 250 percent of normal thrust. Stacks of up to five bearings have been reported.

In-line ball check valves are suitable for application in horizontal or vertical lines. When the flow is suspected to be pulsating and low, use of a swing check valve is not recommended. Due to the continuous flapping of the swing disc against the seat, valves suffer considerable damage, and at times the swing discs can come loose.

How do I determine the loads on a bearing? - Bearing Tips
So here we have a shaft and we have a ball bearing, and the radial load is the load that's perpendicular to the shift. So it doesn't matter if the shaft is going towards vertical. The radial load will always be perpendicular to the actions of the shaft. The axial load and the thrust load will be parallel to the axis.

Ball Mills - an overview | ScienceDirect Topics
Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on small and large scales. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction, and kinetic energy between two or more elements vary greatly within the ball charge.
