Do you know the features of cam with roller follower?

The cam with roller follower is a bearing with a rod end with needle rollers installed in the outer ring. It is a bearing designed for outer ring rotation with a low friction coefficient and excellent rotation performance. In order to effectively increase the load range, the radial clearance of this cam with roller follower is designed to be smaller than that of general needle roller bearings. Therefore, the impact load can be reduced and a stable long life can be obtained. The rod end is threaded or graded, which is easy to install. Cam follower bearings have high rigidity and high precision as cam with roller follower mechanisms and linear motion, and are widely used in machine tools, industrial robots, electronic components, and office automation equipment. The stainless steel cam follower bearing has excellent corrosion resistance and is also suitable for use in places where grease is not suitable or where there is splashing water and clean rooms.

 
The cam with roller follower is a component in a piston engine. Its function is to control the opening and closing of the valve. Although the speed of the camshaft in a four-stroke engine is half that of the crankshaft (in a two-stroke engine, the speed of the camshaft is the same as the crankshaft), but usually its speed is still very high, and it needs to bear a lot of torque. Camshafts have high requirements in terms of strength and support, and their material is generally special cast iron, and occasionally forgings are also used. Since the valve motion law is related to the power and operating characteristics of an engine, the camshaft design occupies a very important position in the engine design process.

cam with roller follower features
1. Combined structure of thick outer ring needle roller bearing and bolt
2. There are metric series and imperial series in size
3. Lubricating oil channels are provided in the bolts of the bearing
4. In order to facilitate installation, there are "one-character" and "hexagonal hole type" wrench assembly methods on the big end of the bearing.
5. The outer surface of the outer ring has cylindrical and spherical shapes, which can be selected according to the actual application.
6. The full roller type is suitable for large loads and low speed occasions
7. The eccentric type can easily and accurately adjust the axis position of the bolt when installing the bearing
