Japanese wheel bearings maintenance

Japanese wheel bearings use outer ring of the roller bearing is filled with cylindrical roller bearing with thicker outer ring wall.The outer diameter surface of the japanese wheel bearings has cylindrical shape and arc shape,which can be designed to match the raceway surface according to the use situation.

Assembly of japanese wheel bearings:
1) the main roller
The main roller is a set of compound roller in the most important carrier, mainly bear the vertical direction of the load and impact load, has a strong impact resistance, wear resistance and corrosion resistance.
2) side rollers
The side roller is the second carrier of a set of compound roller, which mainly bears the horizontal load and also has strong impact resistance, abrasion resistance and corrosion resistance.
3) shaft head
The shaft head is the part connected between the compound roller and the machine equipment. Usually, the shaft head head is designed for chamfering, which is convenient for installation. The shaft head can be directly welded to the japanese wheel bearings.
4) plate
The cover plate is an important part of fixing the side roller inside the shaft head, the main roller outside the shaft head with nuts and thread glue at the end of the shaft head.

Maintenance for japanese wheel bearings:
Use thin oil lubrication: the advantage is that the internal friction coefficient is small, so to overcome the friction consumption of energy, thin oil mobility, easy to enter the friction surface of each lubrication point, has a good cooling effect, and can adhere to the impurities on the friction surface and the metal particles generated by grinding away.The disadvantage for japanese wheel bearings is that the oil film can not withstand large unit pressure, high requirements for sealing.
