Description-York Roller Bearing CF8

GJP York Roller Bearing CF8, which is a needle roller bearing also, and has a stud instead of a shaft, and has a screw on the stud, the screw could be female and male one, and there is screwdriver slot on the bearing end of the stud, for the outer race, in order to enlarge the loading capacity, normally the race was degined by GJP with thick wall.

For this Compact Bearing, the build-in needle rollers are guided by the retainer, while the outer race is guided by the shaft on the stud, these products are applicable for taking heavy loading and middle speed rotation, and it could be desgined by GJP with the sealing type also, the lubricating grease could improve the bearing itself to have longer life time due to the bigger grease filling space inside the bearing.

During the application, when the users assemble GJP cam follower bearings into the machine, as the longer shaft of stud and the contacting thinker outer race contact on the stud, the loading was spread into two direction when the radial loading was put, and if the cam follower bearing is working, the outer race will have the elastic deformation and thus to change the radial afford, the peek loading capacity for bearing radial capacity will increase while the dynamic and stable loading capacity will decrease, at the same time, selection of “being as yoke type track rollers” column will be suitable, in General citcases, the load on the cam follower bearing is partial load, so not tight combination of the shaft is required.

 

The yoke roller bearing refers to an important part that supports the roller and keeps it in the correct position in the frame. The requirements for the yoke roller bearing are small friction coefficient, sufficient strength, small deformation, long life, and easy roller change. The operation of yoke roller bearings is characterized by very high specific loads due to the considerable rolling forces in the short roll necks.

The working characteristics of yoke roller bearing

The yoke roller bearing is used to support the rotating roller and is an important part in the working stand of the rolling mill. It has the following working characteristics:

  1. The working load is large and the radial dimension is limited. In the steel rolling process, the rolling moment is large, and it is accompanied by an impact load; because the rolling process requires that the outer dimension of the roll bearing seat must be smaller than the minimum diameter of the roll body, the outer dimension of the roll bearing is limited and the unit load is large.
  2. The operating speed varies greatly. The operating speed of different rolling mills varies greatly, such as from 0.2 to 120 m/s, and when the rolling mill is reversibly rolled, the rolling mill bearings are frequently forward and reverse. It can be seen that different forms of bearings should be used for rolling mills with different speeds.
  3. Bad working environment. During hot rolling mill rolling, the ambient temperature is high, and the roll cooling water and iron oxide scale splash; during cold rolling mill rolling, process lubricants (such as emulsion, rolling oil) are used to lubricate and cool the rolls and rolling pieces, and there are also imported products. The possibility of human bearing. Therefore, higher requirements are placed on the seal of the roll bearing.

The outer ring of the yoke roller bearing adopts a full complement cylindrical roller bearing with a thicker outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, which can be designed to match the raceway surface according to the application. With this outer ring, the roller can roll directly on the raceway and can withstand heavy loads and shock loads. The yoke roller bearing has a sealed structure and is filled with grease to provide long-term effective lubrication. The yoke roller bearing allows users to avoid lubrication. For the use of harsh working conditions, a channel for replenishing grease can be designed to improve the service life of the bearing. Improper methods can also cause the roller bearing to heat up. Lubrication can reduce the wear and tear of parts in motion, ensure the precision of the press, and reduce energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication and so on.

Advantages of thin oil lubrication

The internal friction coefficient is small, so the energy consumption to overcome the friction force is small. Thin oil has good fluidity and is easy to enter the friction surface of each lubrication point. It has a good cooling effect and can take away impurities adhering to the friction surface and metal particles produced by grinding.
