What Is The Porsche Ball Bearing Cage?

The ball bearing cage, just like other parts of your car, come with a list of functions. Otherwise, they will not be included as a part of the ball bearing. Also known as the ball bearing retainer or ball separator, this component is actually tasked to separate the balls while also maintaining the symmetrical radial spacing in these balls. Also, the Porsche ball bearing cage is tasked to hold the bearings together.

What are the Other Functions of the Cage?

The cage can actually be utilized too when lubricating the ball bearings. It acts as a reservoir for oil or can also be supplied with a coating of oil on it. With this critical function, car makers have carefully chosen their respective ball bearing cages so that they can be used for the specific application with which they are known to help with. The careful choice will assure that the bearing will reach each lifespan while also improving bearing performance.

Common Terminologies Associated with Ball Bearing Cages

One of the most important things you must consider when learning about complex terminologies like a ball bearing cages is to become familiar with other words associated with their use. The list of words below will help you to understand ball bearing cage functions better.

  • Ball pocket – This is that part of the cage that is responsible for positioning the ball. You will easily realize that the ball cage is functioning right when the ball touches the ball pocket right at the balls' pitch circle. In case you notice that contact has been made above or below that of the pitch circle, retainer hang-up will take place too. This can be an indication of a problem in the ball bearing cage.
  • Coined ball pocket – This is usually found in metallic brown ball bearing cages. In this case, an oversized ball is drawn and comes in contact with the spherical surface. This is where the balls come in contact with each other. The retainer, in this case, will be hardened thus allowing it to be snapped into the bearing without deforming the ears or tabs.
  • Loose clinch – It is important that ribbon retainers are loosely clinched in order to allow the balls to orient what are called retainer halves. Also known as the crimp, the loose clinch will help reduce the noise produced during contact while also starting torque and lowering the runner.
  • Tabs – Also known as ears, tabs are signified as protrusions found on the male half of the ribbon retainer. The male half is clinched over the female retainer half. The tabs are responsible for holding the female half together with the male half.
  • Slot-In the case of crown-type retainers, a slot will be found. This is the opening where the ball passes through in the course of bearing assembly before it enters into the ball pocket.

There are a lot of things you must be familiar with when learning about the ball bearing cage. The functions and terminologies above will help you a great deal to know more about the functions of such ball bearing components.
