Outer spherical ball bearings with housings are composed of sealed outer spherical ball bearings on both sides and cast (or stamped steel plate) bearing housings. The internal structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the inner ring of this bearing is wider than the outer ring.

The most common arrangement is a hybrid bearing, usually with stainless steel rings and ceramic balls. The most common ceramic material used is silicon nitride. Balls made from this material are hard, up to Rc78, and have a very smooth surface. Hybrid bearings are more expensive than all stainless steel bearings.

"Bearing balls" is the general term for any hard steel ball that will function in a roller bearing application. Common materials are hard chrome steel 52100, C/S, 440C hard stainless steel and carbonized high carbon steel. High speed steel might be added to this list for severe and high temperature applications.

Another place where balls are widely used is in the plumbing of pneumatic and hydraulic systems. Ball check valves, flow control valves, pressure relief valves and pressure regulating valves all use ball and seat combinations to perform their functions. In pure hydraulic oil systems, the most common ball material is chrome alloy 52100 steel.

Visually inspect the control arm bushings for cracking, splitting, tears, missing parts, and oil saturation. When inspecting ball joints, first look to see if the rubber boots holding the grease inside the ball joint are in good shape. If the boot is torn, or just plain gone, chances are the ball joint is in the process of failing.

This type of gasket is available in a wide range of metals, including brass, copper, copper-nickel alloys, steel, Monel, and aluminum. Corrugated metal gaskets can be manufactured to just about any shape and size required. The thickness of the metal is normally 0.25 or 0.3 mm, with corrugations having a pitch of 1.6, 3.2, and 6.4 mm.

Ball valves are shutoff valves that use a ball to stop or start the flow of fluid downstream of the valve. The ball, shown in Figure 7-1, performs the same function as the disc in other valves. As the valve handle is turned to open the valve, the ball rotates to a point where part or the entire hole that is machined through the ball is in line ...

Bearing Lubrication plays a vital role in the performance and life of rolling element bearings. The most important task of the lubricant is to separate parts moving relative to one another (balls or rollers and raceways) in order to minimize friction and prevent wear. A lubricant that is designed for specific operating conditions will provide a ...
