Characteristics and construction of stainless steel track roller bearings
characteristic of stainless steel track roller bearings
The stainless steel track roller bearings ring and rolling element material are vacuum-quenched and tempered by AISI SUS440C stainless steel (domestic grade: 9Cr18Mo, 9Cr18). The frame material of the cage and seal ring is made of AISI304 stainless steel (domestic grade: OCr18Ni9). Compared with ordinary bearing steel, stainless steel bearings have stronger rust and corrosion resistance. Choose suitable lubricants, dustproof covers, etc., and can be used in the environment of -60 ° C ~ +300 ° C.
Stainless steel stainless steel track roller bearings resist corrosion caused by moisture and several other media. This type of single row deep groove ball bearing has the same deep bearing groove as the standard stainless steel track roller bearings made of carbon chromium (rolling bearing) steel, and the degree of fit between the bearing race and the ball is extremely high. Stainless steel bearings are widely used in food processing, medical equipment, and pharmaceutical machinery due to their high mechanical strength and load capacity.
Structure of stainless steel track roller bearings
The stainless steel track roller bearings 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. Improper means can also cause the roller bearing to heat up. Run
Slip can reduce wear and tear in parts movement, ensure press accuracy and reduce energy consumption. Lubrication is divided into thin oil lubrication, concentrated oil lubrication, etc.
Composition of combined roller bearings
1) Main wheel of stainless steel track roller bearings
The main roller is the most important carrier of a set of composite rollers. It is mainly subjected to 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) Side roller of stainless steel track roller bearings
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) Shaft head f stainless steel track roller bearings
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 connection with round holes. The board and equipment are assembled on the board.
4) Cover of stainless steel track roller bearings
The function of the cover plate is to form an important part of the side roller mounted inside the shaft head, the main roller outside the shaft head with a nut and a thread glue fixed at the tail end of the shaft head.
