BEARING PARTS

PARTS A BEARING: As a general rule, the bearings are basically formed by two rings, rolling elements and a cage. Some of these elements are those that will serve, among others, to classify them according to their differences in design and structure.

The base of the “bearings” is formed by two concentric rings called outer ring and inner ring whose manufacturing material will determine whether it is “Steel bearings”, “Stainless steel bearings”, “Ceramic bearings”, etc.

These rings have the mission of housing some rolling elements that can be balls or rollers so that they move on their raceways without any difficulty. The rollers can be tapered rollers, cylindrical rollers or needles which will allow their classification into Ball bearings “(the most common),” Tapered roller bearings “,” Cylindrical roller bearings “or” Needle roller bearings “.

 

The cage is the separating component that allows the balls or rollers to be fixed equidistant. It is usually made of stamped steel sheet, but also of nylon, brass, or simply not included in the bearing, as would be the case of the VMax Series Bearings for bicycle whose execution makes them contain one more ball and roll of free way.

 

Steel or rubber caps are a common element since they prevent the entry of pollutants into the bearing. The execution of these seals can be made of steel or rubber “2RS” on both sides, “ZZ” or “2RS” respectively, on one side or none as would be the case of known as “open” bearings.
