68321626 Needle Bearing Segment Of Brake Caliper For Meritor ELSA-2 /ELSA-225H

Brake caliper needle roller bearing is one of the main safety components of automobiles. This type of bearing can reduce the friction coefficient, overcome a large amount of consumption, and also reduce oil consumption in automobiles. Sometimes, it can also have a good cooling effect.

Product principle:

When the brake pedal is pressed, the piston pushes the master cylinder forward. Generate pressure in the brake fluid in the cylinder and press the oil into each brake wheel cylinder through the oil pipe. At this point, the wheel cylinder piston opens outward, pushing the brake shoes into contact with the brake drum, producing a braking effect.

Product advantages:

1, Ensuring driving safety and extending brake life

After installing the semi-circular needle roller bearing on the brake, its concave convex axis moving surface will not wear out due to frequent swinging. Simply put, the resilient outer raceway effectively resolves various powerful impact forces, and the concave convex axis does not directly contact during pressure bearing movement, resulting in no noise or high temperature, effectively ensuring driving safety and extending the service life of the brake.

2, Advantages of semi-circular needle roller bearings compared to ordinary bearings

1. Can maintain bearing function even under high loads

Ordinary bearings are also hindered in rotation after being subjected to heavy pressure. The small diameter and densely arranged roller bodies are in linear contact, with a large contact force surface and a small rolling element diameter, making them very flexible in rotation. When subjected to heavy pressure, the evenly distributed pressure is greatly reduced, and they will not sink into deformation. In addition, the flexibility of the rolling elements does not affect their rotational function at all.

2. Small installation space

The outer raceway of the product design is made of thin-walled high-quality steel plate, and the inner raceway adopts the original convex shaft. The rolling element diameter is small, which can save more installation space.

3. Strong impact resistance

The shell is made of high-quality cold plate extrusion molding, and after carbon nitrogen co diffusion treatment, the surface has strong hardness to resist wear and also has good toughness, which will not break or shatter when subjected to strong impact.
