Combined roller bearing characteristics and structural composition

Combined roller bearing features:

The outer ring is a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, and can be matched with the raceway surface according to the design of the use occasion. With this outer ring, the roller can roll directly on the raceway and can withstand heavy loads and shock loads. The bearing is a sealed structure, filled with grease, providing long-term effective lubrication, and users can be free of lubrication. Improve the bearing life by using a channel that can be designed with replenishing grease in harsh conditions.

Combined roller bearing structure:

1. The main roller is the most important carrier of a set of composite rollers. It mainly bears the vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full complement roller bearing, it can also be used as a one-way bearing alone.

2. The side roller is the second carrier of a set of composite rollers, which is mainly subjected to horizontal load, and also has strong impact resistance, wear resistance and corrosion resistance. The side roller is designed with no inner ring full needle roller, and a core shaft replaces the inner ring and the shaft head to carry the bearing.

3. The shaft head is used as the part of the composite roller and the machine equipment. Usually the head of the shaft head is chamfered for easy installation. The shaft head can be directly welded to the equipment, or the shaft head can be welded to the hole with a round hole. The connecting plate and the device are assembled on the connecting plate.

4. The function of the cover plate is to install the side roller inside the shaft head, the main roller outside the shaft head with the nut and the thread glue to fix the important part of the shaft head together.
