The first is the size limit.
Usually the space in which SKF bearings can be installed is limited. In most cases, the shaft diameter (or bearing inner diameter) is limited by mechanical design or other design. Therefore, the choice of bearing type and size is determined by the inner diameter of the SKF bearing. As a result, the main dimensions of standard SKF bearings are based on the international standard internal diameter dimensions.
Standard SKF bearings are available in a wide range of sizes. It is best to use standard SKF bearings when designing mechanical devices. (This design is easy to purchase from SKF bearings. Here is a question. Some models on the bearing catalogue do have some, but some The SKF bearing is not in stock in mainland China, and sometimes the futures will be for a long time, so the time cost and the cost of later replacement should be taken into account when selecting the bearing. The load of the SKF bearing, the load applied to the bearing, its nature and size. The direction is changeable. Usually, the rated base load is shown on the dimension table. However, axial load and radial load are also important factors in selecting a suitable SKF bearing. When the size of the ball and needle bearing is equivalent, the needle bearing usually has a high load capacity and withstands large vibration and shock loads.
Followed by the speed.
The allowable speed is determined by factors such as the type, size, accuracy, cage type, load, lubrication method, and cooling method of the SKF bearing. The permissible speeds of standard-precision SKF bearings under oil lubrication and grease lubrication are listed on the SKF bearing table. Generally, deep groove ball bearings, self-aligning ball bearings, and cylindrical roller bearings are suitable for high-speed operation.
