Detailed information on the individual bearings types, including their characteristics and the available designs, can be found in the sections dealing with individual "bearing types" . Bearing types that are not included in the matrix are generally only used for a few well-defined applications.

The matrix permits only a relatively superficial classification of bearings types. The limited number of symbols does not allow an exact differentiation and some properties do not depend solely on bearing design. For example, the stiffness of an arrangement incorporating angular contact ball bearings or tapered roller bearings also depends on the applied preload and the operating speed which is influenced by the precision of the bearing and its associated components as well as by the cage design. In spite of its limitations, the matrix should enable an appropriate choice of bearing type to be made. It should also be considered that the total cost of a bearing arrangement and inventory considerations could also influence the final choice.

Other important criteria to be observed when designing a bearing arrangement including load carrying capacity and life, friction, permissible speeds, bearing internal clearance or preload, lubrication and sealing are dealt with in depth in separate sections of this catalogue.

There are numerous different kinds of nsk bearings that are designed to handle radial load, thrust load, or some combination of the two. Because different applications require bearings that are designed to handle a specific kind of load and different amounts of weight, the differences between types of bearings concern load type and ability to handle weight.Pressed steel or machined brass cages are generally used, but sometimes molded polyamide cages are also used.

So those are your basic types of bearings. You can also get different ABEC ratings, there's ABEC five and seven just kinda like skateboards. There's even ceramic ina bearings. Ceramic bearings spin for an incredibly long time, it's not incredibly needed though. If you just get your basic ball bearing with your yo-yo, it should be enough and with a little lube and cleaning which we're going to be talking about in the next segment, you can make it play as good as it needs to be.
