The axis of the shaft may vertical or horizontal. If the axis of the shaft is vertical, the thrust bearing is known as footstep bearing. If the axis of the shaft is horizontal, the thrust bearing is known as a roller bearing. #3 Foot Step Bearing. The figure shows a simple type of footstep bearing. It is suitable for supporting a vertical shaft.
Check Valves Types, Construction, Applications and ...
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.

Five things to consider in vertical applications
Ball mill operation is often regarded as something of a mystery for several reasons. Ball milling is not an art - it's just physics. The first problem will ball mills is that we cannot see what is occurring in the mill. The other problem is that many of the independent variables are non-linear or have paradoxical effects on the end results.

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.
Introduction to Check Valves - The Process Piping
Ball Check Valve is a is a check valve in which the closure member is ball shaped and allowed to travel without being closely guided. When the valve closes, the ball-shaped closure member rolls into the seat to achieve the required alignment of the seating's. In some ball check valves, the ball is spring-loaded to help keep it shut.

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.
