We will make the difference between rolling bearing cages, nylon cages, and plastic cages for you first
The function and structural characteristics of bearing cages
1. The cage separates the rolling elements equally spaced and evenly distributed on the circumference of the raceway
2. Guide and drive the rolling element to roll on the correct raceway,
3. In separable bearings, combine the rolling element with the ring to prevent the rolling element from falling off.
The Function and Structural Characteristics of Nylon Cage
(1) The cage separates the rolling elements at equal distances and evenly distributes them on the circumference of the raceway to prevent collisions and friction between the rolling elements during operation;
(2) Guide and drive the rolling element to roll on the correct raceway;
(3) In separated bearings, the rolling element is combined with a ring to prevent the rolling element from falling off.
The Function and Structural Characteristics of Plastic Cages
1. Great flexibility in product design.
2. The centrifugal force of the cage is very small.
3. Anti friction and wear resistance, low bearing temperature rise.
4. Plastic cages have good toughness, impact resistance, and fracture resistance.
5. Acid resistance and corrosion resistance: Engineering plastics have significantly better acid and corrosion resistance than metals.
