Precautions For Using SFK Imported Bearings For Speed Transmission

1. Understand the shape and connection dimensions of the SFK imported bearing for speed transmission.

2. The SFK imported bearing for speed transmission can be installed horizontally, vertically, or at an angle. It can rotate in both directions. It can input and output power in both directions (i.e., deceleration or acceleration).

3. Regardless of the installation method, the SFK imported bearing for speed transmission has dimensional fit requirements with its connecting parts.

Recommended fits: Inner ring bore d fits the shaft according to h7/h6; Middle ring pin hole do fits the drive shaft according to h7/r6; Outer ring d fits the housing according to h8/h7; The fit between the drive shaft and the output shaft bore is a clearance fit with a clearance of 0.2~0.5mm.

4. Axial positioning of the SFK imported bearing for speed transmission: After axially positioning any one of the three rings, the other two shafts do not need to be axially positioned again.

5. Rotation direction positioning: The outer and inner rings are positioned using flat keys. The middle ring is positioned using the drive shaft.

6. SFK imported bearings for speed transmissions can withstand small external forces in the radial direction, but are not suitable for large working loads.

7. The transmission ratios are based on the first installation method. If other installation methods are used, the transmission ratio should be calculated.

8. At the rated speed (1500 rpm), select the SFK imported bearing model for speed transmissions based on the transmission ratio and the required power (kW).

9. When based on working torque, the corresponding model must be selected.

10. The model of the reducer should be consistent with the model of the SFK imported bearing for speed transmissions.
