Roller bearing outer ring with thick outer ring wall full complement cylindrical roller bearings, roller diameter cylindrical and curved, according to the use of occasions designed to meet with the raceway surface. Using this outer ring, the roller can roll directly on the raceway, and can withstand heavier loads and shock loads. The bearing is sealed structure, filled with grease, providing long-term effective lubrication, the user can avoid lubrication. For the use of bad working conditions can be designed to add grease the channel, to improve bearing life. Improper way can also cause the roller bearing heat. Through the Run, Slip can reduce the movement of parts in the wear and tear, to ensure that the press accuracy and reduce energy consumption. Lubrication sub-thin oil lubrication, thick oil lubrication.

Composition of combined roller bearing

1) Main roller
The main roller is a composite wheel which is the most important carrier, the main vertical load and impact load, has a strong impact resistance, wear resistance and corrosion resistance. As the main roller for the full complement of roller bearings can also be used as a one-way bearing alone.

2) Side rollers
The side roller is the second bearing body of a composite roller, mainly bear horizontal load, also has strong impact resistance, abrasion resistance and corrosion resistance. Side roller is full of needle without inner ring design, by a mandrel instead of the inner ring and the first axis of bearing load.

3) Shaft head
Shaft head is a part of the composite roller and machine equipment connection, usually the head is designed to chamfer the head, easy to install, can be directly connected to the shaft head welding equipment can also be welded to the shaft head with a round hole in the connection The board is then assembled with the device.

4) Cover plate
The role of the cover is installed in the shaft head side of the side of the wheel, the outer head of the main roller nut and thread glue in the rear end of the shaft fixed together an important part.

Dilute oil lubrication: the advantage is a small coefficient of friction, so to overcome the friction of the energy consumption, thin oil mobility, easy access to the lubrication of the friction surface, with good cooling effect, and can be attached to the friction surface Of the impurities and the metal particles generated by the grinding. The disadvantage is that the oil film can not afford a large unit pressure, the sealing requirements. High-speed presses generally use a large flow of thin oil lubrication, you can take away the heat generated by the friction.
