Many customers may sometimes have such questions when using ina bearings. Why do some ina bearings have cages while others do not.
Ina bearings (especially rolling ina bearings) are divided into two structures with and without cages. Among them, large ina bearings are generally required to bear large loads, often without cages, but filled with rolling elements between the inner and outer raceways. Most small and medium-sized rolling ina bearings are equipped with cages.
In the processing process of characteristics of INA Bearing Cage, how do the outer ring, inner ring, rolling element and cage of INA Bearing fit together. To put it simply, first put the inner and outer rings of characteristics of INA Bearing Cage, put the inner ring aside, then put the rolling element (put it aside), then adjust the position of the rolling element, and then put the cage.Cage is also involved in the processing of INA Bearing, so what role does characteristics of INA Bearing Cage play?
And drive the rolling body to roll on the correct raceway;
The cage separates the rolling elements at an equal distance and evenly distributes them on the circumference of the raceway to prevent the rolling elements from colliding and rubbing each other during operation;
In the separate characteristics of INA Bearing Cage, the rolling element and a ferrule are combined to prevent the rolling element from falling off.
Ina bearing is called window, which is used to isolate the rolling element. The pocket clearance makes the cage have a certain amount of activity in the radial and axial directions. The total amount of activity in the radial direction is called the clearance of the cage.
There are many structural types and complex shapes in roller cages. There are many equally spaced pockets on the cage. The shape of the pockets is spherical, circular, elliptical, rectangular and toothed, and its size is larger than the size of the rolling body. The difference between the two is the pocket gap characteristics of INA Bearing Cage. Sometimes, the connecting part between the windows of the rolling cage is called lintel, which plays the role of connecting and increasing the strength of the cage.
