Cooperate with

The recommended fit for rod ends of CAM driven bearings is shown in Tables 3 and 4. Because it is fixed on one side, so for the special load impact load part, please process the mounting hole to make the fitting part does not produce clearance.

Allow the speed

The allowable speed of CAM driven bearing is affected by the installation and use conditions. The D1N value under pure radial load should be below the maximum value shown in Table 5. Under actual conditions of use, the value of D1N should be the recommended value as shown in Table 5, considering the effect of axial load.

lubrication

The bearing sealed with grease is shown in Table 6. The sealed grease is Mobil and Shell grease S2.

For bearings without grease seal, please add grease from the oil hole on the rod end. If you do not add oil, it will increase the wear of the sliding contact surface and shorten the service life.
